Metaproteomics of microbial community in the fermented rice for melanogenesis inhibitor synthesis

Project description:The microbial community and enzymes in fermented rice using defined microbial starter, containing Rhizopus oryzae, Saccharomycopsis fibuligera, Saccharomyces cerevisiae and Pediococcus pentosaceus, play an important role in quality of the fermented rice product and its biological activities including melanogenesis inhibitory activity. The microbial metaproteome revealed large-scale proteins expressed by the microbial community to better understand the role of microbiota in the fermented rice.

In vitro investigations on the impact of constituents on fermented dairy on fecal microbiota composition

Project description:The consumption of fermented food has been linked to positive health outcomes due to a variety of functional properties. Fermented dairy constitutes a major dietary source and contains lactoseas main carbohydrate and living starter cultures. To investigate whether nutritional and microbial modulation impacted intestinal microbiota composition and activity, we employed fecal microbiota fermentations and a dairy model system consisting of lactose and β-galactosidase positive and negative Streptococcus thermophilus. Based on 16S rRNA gene based microbial community analysis, we observed that lactose addition increased the abundance of Bifidobacteriaceae, and of Veillonellaceae and Enterobacteraceae in selected samples. The supplied lactose was hydrolysed within 24 h of fermentation and led to higher expression of community indigenous β-galactosidases. Targeted protein analysis confirmed that bifidobacteria contributed most β-galactosidases together with other taxa including Escherichia coli and Anaerobutyricum hallii. Lactose addition led to 1.1-1.8 fold higher levels of butyrate compared to controls likely due to (i) lactate-crossfeeding and (ii) direct lactose metabolism by butyrate producing Anaerobutyricum and Faecalibacterium spp. Representatives of both genera used lactose to produce butyrate in single cultures. When supplemented at around 5.5 log cells mL-1, S. thermophilus or its beta-galactosidase negative mutant outnumbered the indigenous Streptococcaceae population at the beginning of fermentation but had no impact on lactose utilisation and final SCFA profiles. This study brings forward new fundamental insight into interactions of major constituents of fermented dairy with the intestinal microbiota. We provide evidence that lactose addition increases fecal microbiota production of butyrate through cross-feeding and direct metabolism without contribution of starter cultures.

Kimchi intake promotes antigen-presenting cell signaling and CD4⁺ T cell remodeling without inducing systemic immune activation: A single-cell RNA-seq substudy of a randomized, double-blind, placebo-controlled clinical trial

Project description:This study aimed to investigate the systemic immunological effects of kimchi consumption in humans. We conducted a 12-week randomized, double-blind, placebo-controlled clinical trial involving thirteen overweight but otherwise healthy adults who consumed either placebo, spontaneously fermented kimchi (S-K), or starter kimchi fermented with Leuconostoc mesenteroides KCKM0828 (LMS-K). Peripheral blood mononuclear cells (PBMCs) were collected before and after the intervention and subjected to single-cell RNA sequencing (scRNA-seq) to profile immune responses at single-cell resolution.

Gene expression profile of Lactobacillus casei Zhang in fermented milk during transit in simulated gastrointestinal tract

Project description:The survival of probiotics could be strongly enhanced by delivery vehicles, but the mechanism was unknown. In this study, whole genome microarray technology was used to detect the gene expression profiles of probiotic Lactobacillus casei Zhang in the absence and presence of fermented milk in simulated gastrointestinal tract. The results showed the gene expression profiles were significantly different under these two different conditions. The change of the gene expression profile may be helpful to comprehend the role of delivery vehicles in enhancing the survival of probiotics. Twelve samples of bacterial cells in the absence and presence of fermented milk were collected at 3 h in simulated gastric juice, 4 h and 8 h in intestinal juice, 2 biological replicates were obtained in each time point. The average of the normalized expression values of the 2 biological replicates for each probe was regarded as the expression value of a predicted gene. To identify the expression pattern of each gene across different treatments, n-fold change ratios were calculated for every gene in pure L. casei Zhang versus L. casei Zhang in fermented milk.

Temporal gene expression and probiotic attributes of Lactobacillus acidophilus during growth in milk

Project description:Lactic acid bacteria have been used as starter strains in the production of fermented dairy products for centuries. Lactobacillus acidophilus is a widely recognized probiotic bacteria commonly added to yogurt and used in dietary supplements. In this study, a whole genome microarray was employed to monitor gene expression of L. acidophilus cells propagated in 11% skim milk (SM) during early, mid and late logarithmic phase, and stationary phase. Approximately 21% of 1,864 ORFs were differentially expressed at least in one time point. Genes differentially expressed in SM included several members of the proteolytic enzyme system. Expression of prtP (proteinase precursor) and prtM (maturase) increased over time as well as several peptidases and transport systems. Expression of Opp1 (oligopeptide transport system 1) was highest at 4h, while gene expression of Opp2 increased over time reaching its highest level at 12h, suggesting that the two systems have different specificities. Expression of a two-component regulatory system (2CRS), previously shown to regulate acid tolerance and proteolytic activity, also increased during the early log and early stationary phases of growth. Expression of the genes involved in lactose utilization increased immediately (5 min) upon exposure to milk. The acidification activity, survival under storage conditions, and adhesion to mucin and Caco-2 tissue culture cells of selected mutants containing insertionally inactivated genes differentially expressed in the wild-type strain during growth in milk were examined for any potential links between probiotic properties and bacterial growth and survival in milk. Some of the most interesting genes found to be expressed in milk were correlated with signaling (AI-2) and adherence to mucin and intestinal epithelial cells, in vitro.

The first application of biological pretreatment in Chinese spirits, utilizing cellulose-degrading probiotics from Jiangshui to improve the quality of Highland Barely Liquor

Project description:Highland barley liquor is a distilled spirit made from highland barley on the Tibetan Plateau, but its alcohol yield is limited by the high fiber content of the raw material. In the field of biomass resources, functional microorganisms are commonly used in pretreatment to degrade cellulose and other substances, improving fermentation output. In this study, we isolated the cellulose-degrading probiotic Lactobacillus delbrueckii GR-8 (CMCase 6.21 U/mL) from the traditional vegetable-based fermented food "Jiangshui" and applied biological pretreatment to the fermentation of highland barley liquor. During pretreatment, probiotics enhanced cellulase and amylase activities in the fermented grains, resulting in a 25% reduction in cellulose content and a 112% increase in free reducing sugar content. The pretreatment significantly altered the microbial community structure, enhancing microbial diversity. After distillation, alcohol yield increased by 3.5%, and total acid and ester contents rose by 25% and 23%, respectively. Pyrazine compounds increased by 1290%, while higher alcohols like nonanol, phenylethanol, and hexanol decreased. The treated liquor caused less harm to mice, who showed improved memory, motor skills, and lower oxidative liver damage. This study demonstrates that biological pretreatment enhances both fermentation and the quality of Chinese spirits.
