It aims to offer an alternative product the food industry for increasing demands of healthy nutrition with production yogurt containing bee pollen. Probiotic prepared different levels pollen (0.5%, 1.5%, 3% and 6%) were evaluated antimicrobial properties, viability S. thermophilus, L. bulgaricus, acidophilus, Bifidobacterium spp. during 14 days refrigerated storage, resistance in vitro gastrointestinal conditions. Yogurt samples showed activity against monocytogenes, Typhimurium, E. coli, coli O157:H7, aureus at high level cell concentration (108 CFU/mL). The decreased digestion model depending on content bacterial species as application time increased. simulated gastric intestinal juice tolerance bacteria was strain dependent pH-dependent. addition enhanced survival acidophilus both juices.

Abstract From recent literature and research studies, it has been found that some bacterial strains have abilities with probiotic activities to produce B vitamins, which play essential roles in maintaining human health. Oligosaccharides can promote the beneficial microbes, however, specific effects of oligosaccharides on vitamins-producing ability not clarified. This study evaluated effect different properties vitamin-producing 21 selected strains. The obtained results suggested could utilise as sole carbon source, hydrophobicity, auto-aggregation, biofilm formation were regulated after fermentation oligosaccharides. In particular, had influences levels extracellular vitamins produced by These findings provide foundation for studies their application functional foods prevent deficiency.

Psychobiotics are live microorganisms that, when administered in adequate amounts, confer mental health benefits to the host. Several clinical studies have demonstrated significant from psychobiotic administration, making them an emerging topic food science. Certain strains of Lactobacillus, Bifidobacterium, Streptococcus, Escherichia, and Enterococcus species known for their ability modulate gut-brain axis provide benefits. Proposed action mechanisms include production neuroactive compounds or precursors, which may cross blood-brain barrier, transported by extracellular vesicles. However, there is a lack vivo evidence directly confirming these mechanisms, although indirect recent suggest potential pathways further investigation. To advance our understanding, it crucial study within host, with accurate quantification and/or precursors being key such studies. Current methods, however, face challenges, as low sensitivity detecting trace metabolites limited specificity due interference other compounds, impacting reliability measurements. This review discusses field psychobiotics, compound estimation techniques, perspectives improvement quantifying

The global increase in prevalence of (pre-)diabetes demands immediate intervention strategies. In our earlier work, we demonstrated vitro antidiabetic potential a fermented beetroot product (PN39). Here, examined the impact PN39 on glucose tolerance and gut microbiota C57BL/6J male mice prediabetic (PD) subjects' stool microbiota. mice, high-fat diet (HFD) consumption for 9 weeks resulted hyperglycemia impaired (GT) while concomitant HFD (PN39+HFD) prevented GT impairment. Meanwhile, feeding with 5 to induce PD later administering them 4 (PD + PN39) neither improved fasting blood nor GT. Relative control groups, both humans were characterized by decreased Clostridia UCG-014 Lactobacilli as well significantly altered microbial carbohydrate metabolism. Feeding together preserved Lactobacilli, increased short chain fatty acid production relative fed only. Treating subjects however populations acids concentrations stools. humans, treatment rectified metabolism observed their counterparts. This suggests that modulatory effects coupled its capacity regulate metabolism, likely played role preventing receiving PN39+HFD. Taken together, results indicate could act potent functional food diabetes associated dysbiosis.

We identified strains of lactic acid bacteria from fermented potherb mustard that showed excellent fermentation properties. The goal was to identify superior starter cultures would optimize the traditional process, reduce duration, and improve quality pickled mustard. Four were screened: Weissella cibaria (LAB1, LAB3) Leuconostoc mesenteroides (LAB2, LAB4). Then, after in vitro tests tolerance low pH salt levels as well production ability, nitrite degradation antibacterial properties, antioxidant activity, LAB1 LAB2 selected best strains. Next, these two used for fermenting Each inoculated into solution. Compared natural fermentation, both beneficial effects, including reducing content, shortening time, maintaining sugar, increasing nitrogenous amino acids. Microbial diversity analyses revealed that, prior predominant microbial communities Methylobacterium Sphingomonas, which primarily originated surrounding environment. However, 30 days inoculation with strains, there a significant increase abundance Lactobacillus, emerged dominant bacterium. Inoculation effectively stabilized bacterial community significantly enhanced content acids final product, indicating it is highly suitable mono-starter. On other hand, led reduced facilitated proliferation an effective mixed starter. Due its limited effect on production, not recommended mono-starter production.

ABSTRACT The aim of the present study was to characterize probiotic potential Lacticaseibacillus casei 4 N‐6 strain isolated from cow's milk. For this purpose, acid, bile salt, pancreatin, pepsin, phenol, and lysozyme tolerance, co‐aggregation auto‐aggregation properties, phytase production, antibiotic resistance, antibacterial properties were analyzed in vitro. had relatively poor pepsin tolerance. However, showed a high lysozyme, phenol In addition, it exhibited moderate with E. coli good autoaggregation. Furthermore, cell‐free supernatant Lb . antimicrobial activity against Bacillus cereus (N32), Salmonella enteritidis (RK‐485), Enterococcus faecalis (RK‐487). resistant vancomycin, teicoplanin, gentamicin, ceflazidime. did not show hemolytic activity. found be able produce phytase. All findings obtained indicate that is promising as candidate has superior can evaluated future. further research vivo studies are needed fully understand its mechanism action optimize use probiotic.

Human milk oligosaccharides (HMO) play an important role in the growth and development of infants. Some bifidobacteria have been shown to use HMO through conserved strain-specific pathways also different physiological characteristics under carbon sources. Previous studies concentrated on representative strains each genus, yet there is a paucity research metabolic function differences between within subspecies. In this work, we compared Bifidobacterium infantis (B. infantis) CICC 6069 B. Z-081 glucose, lactose, galactooligosaccharides, 2'-fucosyllactose (2'-FL), including metabolic, gastrointestinal digestive resistance, adhesion Caco-2. Compared with type strain 6069, had higher tolerance sources, but its were lower than those 6069. And it was proved that 2'-FL could promote infantis. Furthermore distinct global gene transcription response observed among strains. The results study provide comprehensive understanding genomic 2 infantis, ideas for screening functional probiotics, further support potential application as prebiotic supplement.
