Identification of cultivable lactic acid bacteria isolated from Algerian raw goat’s milk and evaluation of their technological properties. Secondly, to provide some data in relation to their potential use in functional foods that may serve as basic preliminary data in further studies. Ewart (1908) divided the seeds into 3 categories depending upon their life span or longevity: Seeds with life span of a few weeks to 4 years. Al-Farsi, M., Alasalvar, C., Al-Abid, M., Al-Shoail, K., Al-Amry, M., Al-Rawahy, F. Compositional and functional characteristics of dates, syrups, and their by-products. The fruits are used to treat respiratory diseases and fevers. Specifically, the viability of replacing the existing gas boiler in a university building in the south of Spain with a system of biomass boilers using this biomass was analyzed as a case study. Yeast: Origin, Reproduction, Life Cycle and Growth Requirements | Industrial Microbiology, How is Bread Made Step by Step? The ability of the probiotic micro-organisms to utilise the finely ground date seed as a carbon source was determined by counting the colony forming units during the fermentation period (sampling after 0, 24, 48, 72, and 96 hours incubation). It was prepared by removing the glucose substrate from the MRS-Oxoid and adding the remaining ingredients listed on the MRS-Oxoid. After their maturation the seeds do not remain viable indefinitely. The latter (DFC)may have supported the probiotic Lactobacillus growth especially after 48 h incubation (Figure 4). What is its function? Table 1.Different concentrations of tested FGDSP,AEDSP and DFC product (fermentation     media), using isolated same probiotic strain and growth conditions. 1. Pick out and discard any seeds that float to the surface because they are probably not viable. One control flask containing 30 ml distilled water was also used. Share Your Word File Nowadays, there is increasing interest in the investigation, identification and development of novel prebiotic compounds, to support the claim of using functional foods as an alternative approach for promoting health and reducing the risk of diseases (4, 5, 6, 7, 8).

Phoenix dactylifera. The second oldest viable 14C-dated recorded seed is now about 1300 years old sacred lotus (Nelumbo nucifera) seed, recovered from a dry lakebed in north eastern China in 1995 (Shen-Miller et al, 1995). The total numbers of bacterial populations at 0, 24, 48, 72 and 96 h of fermentation were checked for each sample during the fermentation period. The pH values were decreased from 6.2 at the start of fermentation to a pH between 3.2 and 3.9 in all the fermentation assays, which indicated that date seed did not stop one of the main important features for the probiotic to be functional, which is to produce acids.The results of the antimicrobial activities of the three date seed products that were investigated in this study indicated that nosignificant zones of inhibition were observed around the three test discs in the agar diffusion assay compared with the positive control which measured (5 mm) and the negative control. Just to be sure you can use a 1 pint measure (about 550 ml) of vermiculite, moistened with 30 ml (about two tablespoons) of water. ( (iii) positively affects the host health by producing short chain fatty acid and antimicrobial compounds such as acids, bacteriocins and H2O2, in addition to adhesion sites and antagonism on growth substrates (iv) can withstand food processing treatments. The date palm (Phoenix dactylifera L.) is an ancient fruit with significant nutritional, medicinal and economic value.Date fruits are composed of a fleshy pericarp and a single seed. A new experiment on seed germination technique for Phoenix dactylifera, an exotic species was conducted in the nursery of Forestry and Wood Technology Discipline, Khulna University, Bangladesh.The seeds imported from Saudi Arabia were collected from Nirala Central Mosque, Khulna, Bangladesh, in September 2008 and treated with four presowing treatments (control, immersion in … Obviously, all these finding pertain to seeds which sur­vived accidental storage followed by controlled germination and are not indicative of the upper survival time limit of properly stored seeds. The          results    shown   in         table    4      indicate     that     the DFC was   utilized       by      theprobioticLactobacillus. The commercially available medium was used to recover the probiotic cultures and to enumerate them during this study. Date (Phoenix dactylifera L.) seeds are a valuable and abundant by-product with various potential food applications and source of functional and bioactive ingredients. The present study was aimed to investigate the effects of the date palm (Phoenix dactylifera L.) seed products in the form of (i) the finely ground date seeds powder (FGDSP) and (ii) the aqueous extract of date seed powder (AEDSP) on the growth of the lactic acid bacteria (LAB) Lactobacillus paracaseisspparacaseias probiotics. The first product was the ground raw powder which was obtained after milling as a finely ground date seed powder (FGDSP). The aqueous supernatant that was collected contains the soluble carbohydrate and is the second product and referred to as the “aqueous extract of date seed powder” (AEDSP). The seeds – the oldest ever germinated – were among hundreds discovered in caves and in an ancient palace built by King Herod the Great in the 1st century BC. One of the scientific criteria for functional food ingredients to be recognized and classified as a prebiotic is that it inhibits the growth of pathogenic bacteria (23). These colonies were representative of all the colonies and displayed the general features of LAB. 1 ml was taken from that culture and used to inoculate 10 ml of fresh MRS- Oxoid medium. This study has shown that the two date palm substrates FGDSP and AEDSP can potentially be utilized as carbon sources suitable for bacterial fermentation. The below mentioned article provides a study note on the viability or longevity of seeds. (With Methods)| Industrial Microbiology, How is Cheese Made Step by Step: Principles, Production and Process, Enzyme Production and Purification: Extraction & Separation Methods | Industrial Microbiology, Fermentation of Olives: Process, Control, Problems, Abnormalities and Developments, The best answers are voted up and rise to the top. Figure4. The fermentation medium used for the third fermentation assay was prepared by using distilled water supplemented by each of the three different date seeds products (Table 1). Date Palm or Phoenix dactylifera is an evergreen, flowering palm growing up to 30 m tall and up to 40 cm across. The medium was also prepared in the laboratory in its modified form which did not contain a carbon source so that it could be supplemented with the date seed products e.g. What is a mushroom shaped gland? The kernel powder was sieved in a laboratory test sieve to remove the husk and the larger size powder (1000-700 µm) was collected and kept refrigerated at 5 °C until needed to prepare the kernel products using the methods as described by Al-Farsi and Lee (12) with little modifications.Three different products were obtained from these date kernels and subsequently used in this study. For these 10 isolates, further identification was carried out by using the API 50 CHL test, which identified each of the samples as Lactobacillus caseisspcasei. The prebiotic properties of oligofructose at low intake levels. In addition, some sugars are also considered in this category, such as raffinose, lactose, and stachyose, and sugar alcohols, e.g., sorbitol and xylitol. The fermentation was run in triplicate for each sample. However, further investigations need to be carried out by in suitable animal model to corroborate the potential prebiotic effect of the date palm (Phoenix dactylifera L.) seed product dietary fibre concentrate (DFC). This study has shown that date seeds could provide a suitable carbon source for probiotic fermentations and demonstrated their potential as a prebiotic. The Date Palm tree (Phoenix dactylifera L) is one of the oldest cultivated plants and has been used by man for over 6000 years (9). It was carried out on six different samples, four samples that contained different concentrations of FGDSP in synthetic MRS (MRS-C). The life span of seeds which may vary from few weeks to many years depends upon (i) species and (ii) the environmental conditions pre­vailing during seeds storage. Enumeration of probiotic using the date seed product; dietary fibre concentrate (DFC): the numberof probiotic colony forming units (CFU/ml) after 0, 24, 48, 72, 96 h incubation to determine probioticability to utilise the dietary fibre concentrate (DFC) and distilled water. Further biochemical test was performed using the API 50 CHL test strip (bioMerieux). Our mission is to provide an online platform to help students to share notes in Biology. The date is composed of a fleshy pericarp and a seed. Hence, further investigations should be carried out to identify active biological molecules in date seeds and their potential application in encouraging the growth of probiotics and other health benefits. Synonym(s) - NA. It is believed that these viable seeds must have been at least 130 years old and probably even 200-400 years old. Isolated probiotic strains grew in MRS media and reduced the pH of the medium from 6.2 to 3.9. Birollo, G. A., Reinheimer, J. PHOENIX DACTYLIFERA LINN. Figure6.Comparison of the three date seeds products to be used as a substrate by probiotic lactobacilli; thenumber of probiotic colony forming:units (CFU/ml) after 0, 24,48,72,96 h; (DFC, FGDSP and AEDSP). Thus, the probioticLactobacillus may have utilized the date powder (FGDSP) as an additional carbon source tosupport its growth and to increase the total numbers of bacteria in the population. The resulting vermiculite should feel quite dry to the touch. However, the oldest 14 C-dated seed that has grown into a viable plant was Judean date palm (a cultivar of Phoenix dactylifera) seed about 2000 years old, recovered from excavations at Herod the Great’s palace at Masada in Israel. The leaves are 4-6 m long, with spines on the petiole. An API 50 CHL test was carried to determine their sugar fermentation patterns. All these samples in this assay contained the same amount of AEDSP, using the amount that resulted in optimal growth in the first fermentation assay. Phoenix canariensis Chabaud – Canary Island date palm : Species: Phoenix dactylifera L. – date palm : Species: Phoenix loureiroi Kunth – Loureir's date palm : Species: Phoenix reclinata Jacq. L. Family - Arecaceae.. Common Names(s) - Date Palm. Dietary fibre concentrates obtained from date kernels could potentially be an inexpensive source of natural dietary fibre and probably a functional food ingredient(12). TOS4. Where are the pollen grains formed in the flower? Which organelle is known as “power house” of the cell? Seeds with life span varying from 15 years to 100 years or more. FGDSP and AEDSP could be used as a carbon source for bacterial fermentations. The second fermentation assay was conducted by using the AEDSP in the flasks. Thus, as DFC was utilized by the probiotic cultures, it may act as a prebiotic. The three samples, each was containing 30 ml distilled water, different date seeds substrate (DFC, FGDSP or AEDSP), at the same quantity was identified from the first fermentation assay. The total bacterial numbers in the negative control flask (distilled water) werecompared with the other flask containing DFC during the fermentation period. The most significant observation in this assay was that there were no changes in the pH values in the flasks of the MRS-Min + 0.6 ml AEDSP compared to the MRS-Min control flask despite the fact that an increase in the total bacterial number was observed. Effect of the aqueous ethanolic extract from Phoenix dactylifera parthenocarpic dates on MDA-MB-231 and MCF-7 cancer cell lines viability at 24 h (a) and 72 h (b). The very first palm I grew from seed was a Phoenix (dactylifera or Canariensis, I forgot lol) that I collected on the Hollywood Boardwalk in Florida. The ability of R dactylifera to thrive in hot, dry conditions with little or no rain, as long as there is constant moisture about the roots for healthy growth and seed germination, have made it the classic symbol of the oasis. Subsequently, to investigate the prebiotic properties ofthe date palm (Phoenix dactylifera L.) seed product i.e dietary fibre concentrate (DFC) in stimulating the growth of the probiotic. Name the types of nitrogenous bases present in the RNA. Table 5.Enumeration (CFU /ML) of probiotic using DFC, FGDSP and AEDSP. The flasks were filled with 30 ml growth medium (MRS-C, MRS-Min or distilled water + test substrate) and then, the media was sterilized by autoclaving (121°C, 15 min). The seeds were dried at the room temperature. In a recent study, the aqueous extract of P. dactylifera seeds was able to stimulate endogenous insulin secretion through extra- The term “dietary fibre” is applied to all non-digestible polysaccharides. In the second fermentation assay, the aqueous extract of date seed powder (AEDSP) was investigated for its effect on the growth of the probiotic cultures. B., Sharif, F. A., Usda, A. R. S. Preliminary analysis and potential uses of date pits in foods. Thus, exploitation of such waste is very important in date cultivation and to raise income to this sector, especially if that product has a potential use as functional food ingredient in countries where the date palm is grown, such as Middle Eastern countries including Kingdom of Saudi Arabia. The total cell number of probiotics was observed to increase after 24 hr incubation in the MRS-Oxoid positive control with fewer numbers being observed in MRS-Oxoid + 0.6 ml, and fewer again in MRS-Min containing 0.6 ml AEDSP and in the distilled water 0.6 ml of AEDSP. Hence the main objective of the study to analyze the phytochemicals present in the seeds. However, the oldest 14C-dated seed that has grown into a viable plant was Judean date palm (a cultivar of Phoenix dactylifera) seed about 2000 years old, recovered from excavations at Herod the Great’s palace at Masada in Israel. Briefly,10 g FGDSP was added to 600 ml distilled water and the solution was placed on a hotplate at 45 °C, at 120 rpm for 3 h. The aqueous extract was separated from the solid slurry by centrifugation at 1000rpm for 20 min before being filtered through Whatman No. Seeds of Cassia bicapsularis and C. multijuga had been found to remain viable even after 100 years. Get 1 Free Product Today All India Delivery Lowest prices. The total numbers of bacterial populations at 0, 24, 48, 72 and 96 h of fermentation were checked for each sample during the fermentation period. Noticeably, very limited use of date kernels is currently made despite the many thousands of tons of date kernels that are discarded each year. Sap from the tree can be drunk fresh, fermented, or di… Probiotics are defined as “live microorganisms which when administered in adequate amounts confer a health benefit on the host”(FAO/WHO 2002). Mandalari, G., Nueno-Palop, C., Bisignano, G., Wicham, M. S. J., Narbad, A. Dates were collected randomly from tamr (fully ripe dates) batches at the end of the season with no preference to size, colour, appearance, or firmness. An increase in the total numbers of viable bacteria in the FGDSP and AEDSP fermentations (Figure 9) confirmed that these two date seed products could provide a suitable carbon source to support microbial growth. Conclusions: Phoenix dactylifera L. seeds have the potential to inhibit adipogenesis and obesity. It takes forever for me to get these to germinate at room temperature. They are considered as waste material of the several date processing plants that produce date powders, date juice, date confectionery, date syrup, pitted dates, date chocolate and coated dates. A., Vinderola, C. G. Viability of lactic acid microflora in different types of yoghurt. Two control flasks were used, one with distilled water and another one with fully supplemented MRS (commercially available from Oxoid, and described as MRS-Oxoid). All Rights Reserved. Top 35 Interview Questions on Plant Physiology (With Answers). This study analyzes the properties associated with the date seed (Phoenix dactylifera L.) to evaluate its suitability and viability as a new biofuel. Mcclintock, E. Arecaceae palm family. P. dactylifera seeds, when combined with insulin, has provided better glycemic control in diabetic rats without any toxic effect on liver or kidney (El Fouhil et al., 2011). The most surprising observation in this fermentation assay was the decrease in the pH values from 6.2 to 3.9 in distilled water, the same as MRS-Oxoid, MRS-C + 0.6g FGDSP, MRS-C +0.15g and MRS-C + 0.06g FGDSP(Figures 1 and 2). The seeds of most of the crop plants have usually very short life-span and belong to the first category. Circular, convex and whitecolonies, different sizes,surface and entire edge. 1995; 125. What is the significance of transpiration? Place the Phoenix Dactylifera seeds in a sterile medium which is only barely moist but never too wet. Besbes, S., Blecker, C., Deroanne, C., Drira, N. E., Attia, H. Date seeds: chemical composition and characteristic profiles of the lipid fraction. Figure2.Changes in pH values of FGDSP cultures after 96 h incubation in the presence of the substrates as indicated. Date palm (Phoenix dactylifera L.) seeds of the Khalas variety were used in this trial.They were provided by the Al Foah Company-Emirates Dates factory, Al-Ain, United Arab Emirates. The date derivatives are rich in nutraceuticals and phytochemicals. Based on the nutritional profiles of the fat, mineral, protein and carbohydrate content of the date kernels, it has been suggested that date kernels could be regarded as an excellent source of functional foods with interesting technological functionalities that could also be used as an important source of dietary fibre. An increase in the number of the probiotic population in the flask that contained date seed powder was observed in the first fermentation assay. The positive and negative fermentation results were reported as described in the manufacturer’s handbook and the species identification made by a computer program which was used to analyzed the results, as recommended by the manufacturer (bioMerieux). Publication Ethics and Malpractice Statement, http://ucjeps.berkeley.edu/cgi-bin/get_JM_treatment.pl?Phoenix+dactylifera, Source Normalized Impact Per Paper (SNIP): 0.157, Gibson, G. R., Roberfroid, M. B. Dietary modulation of the human colonic microbiota: introducing the concept of prebiotics. This study proposes that date kernels could potentially be a cheap source of prebiotics and could easily be utilized as a functional food ingredient, converting a waste product into an economically viable food substrate. Mandalari, G., NuenoPalop, C., Tuohy, K., Gibson, G. R., Bennett, R. N., Waldron, K. W., Bisignano, G., Narbad, A., Faulds, C. B. Menne, E., Guggenbuhl, N. Fn-type chicory inulin hydrolysate has a prebiotic effect in humans. Worldwide production of dates was around 6.9 million tonnes in 2004, from which about 863 thousand tonnes of date seeds were disposed of as a waste product (12). Generally, date seeds contain high amounts of total carbohydrates, 83.1% as reported by (15). The date seeds also benefited from the dry, dark … One of the observations in this study indicates that growth of the probiotic was supported for 24 to 48 hr of incubation in the distilled water in a negative control in the fermentation assays. The total viable count of the yoghurt was 1.21×107 CFU/ ml. Germination usually takes place in 2 - 3 months This study analyzes the properties associated with the date seed (Phoenix dactylifera L.) to evaluate its suitability and viability as a new biofuel. The viable count of the isolated LAB (probiotic) from Actimel yoghurt was 1.21×107 CFU/g. In the other flasks the pH values decreased as the population number increased (Figure 7). The starting pH is shown in blue and the final pH in. It is a monocotyledonous woody perennial plant belonging to the Arecaceae family, which contains over 200 genera and at least 3000 species (10). Phoenix dactylifera seeds ameliorate early diabetic complications in streptozotocin-induced diabetic rats. It was successfully sprouted in 2005 (Sallon et al, 2008). Answer: Score: 1.01: Is the species highly domesticated? The best known prebiotics are currently the non-digestible oligosaccharides such as fructo-oligosaccharides (FOS), inulin, galacto-oligosaccharides (GOS) and lactulose, all of which are commercially available (4). The Jepson Manual: 1993; Hussein, A. S., Al-Haami, G. A., Khalil, Y. H. The use of dates and date pits in broiler starter and finisher diets. Most studies performed on date seeds have investigated only their chemical composition. An increase in the total cell numbers of the probiotic was also observed in the flasks containing FGDSP and AEDSP, and a pH decrease was also observed. A pH decrease was observed with the test samples of the DFC, pH 3.8 (Figure 5). In general, an increase in the numbers of probiotic was reported in response to the addition of the date seed product (FGDSP) during the fermentation period (96 h), in addition to reducing the pH. Privacy Policy3. Consequently, one of the current challenges in nutrition sciences is improving gut health, using the concept of functional foods as a health promoting tool. The first fermentation assay was conducted by using the FGDSP in the flasks. Overall, this study explored the inhibitory effects of Phoenix dactylifera L. seed extract on adipogenesis in 3T3-L1 cells on the molecular level. The fruits are edible. Inoculated plates were covered with a layer of the same medium to create microaerophilic condition. Subsequently, to investigate the prebiotic properties ofthe date palm (Phoenix dactylifera L.) seed product i.e dietary fibre concentrate (DFC) in stimulating the growth of the probiotic. Besides these two legumes, other seeds with a life span of 75 years or more have also been found to be legumes. The slurry that remains after collecting the AEDSP is the third product and comprises the dietary fibre concentrate (DFC). The DFC presented the potential to be applied as a novel source of prebiotics, by increasing the population of Lactobacillus paracaseisspparacaseias probiotics in addition to decreasing the pH values.This research proposed that date seeds could potentially be utilized as a starting material to manufacture functional food ingredients especially as they are a common waste product, especially in Middle Eastern countries. The test strains were cultivated and maintained by sub culturing on MRS broth for LAB and Nutrient broth for E. coli EMG 14 with 30% (v/v) glycerol at -70°C. There are many food additives known to be non-digestible carbohydrates in the small intestinal tract but that are digested in the colon by colonic microbiota (1).Although all dietary fibres are non-digestible polysaccharides but not all dietary fibres are prebiotics, and not all non-digestible oligosaccharides are prebiotic. The inoculum culture was prepared by inoculating MRS medium and incubating it overnight. A 0.1 ml of the 10-1 sample were then surface plated in duplicate onto MRS agar and aerobically incubated at 28°C for 48 h. Furthermore, 0.1 ml of appropriately diluted samples of reference strains was pour-plated in duplicate on MRS agar and treated the same way as the probiotic sample during its incubation. All these different media were prepared in blue–jacketed flasks (30 ml). Food products containing probiotics and prebiotics in which prebiotics selectively favours probiotics are termed as synbiotics. Optimal mixture predicted for highest phytochemical content corresponds to 22.39%, 37.37%, and 40.24% of acetone, ethanol, and water, respectively. Copyright © 2020 Journal of Pure and Applied Microbiology. A total of 10 isolates were counted and isolated from Actimel drinking yoghurt. The objectives in this study were therefore firstly, to investigate the effects of the date palm (Phoenix dactylifera L.) seed products in two forms (i) finely ground date seeds powders (FGDSP) and (ii) the aqueous extract of date seed powder (AEDSP) on the growth of probiotic lactic acid bacteria (LAB) such as Lactobacillus paracaseisspparacasei. FGDSP in the first fermentation assay, to study that potential of date kernels as a carbon source for prebiotic fermentation. The date seed (DS) exists in a hard-coated form that is elongated, ventrally uneven and contains a small embryo that accounts for approximately 15% of the weight of the fruit (Tafti et al., 2017).
