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.

Project description:Aloe plant species have been used for centuries in traditional medicine and reported to be an important source of natural products. However, despite the large number of species within the Aloe genus, only a few of them have been investigated chemotaxonomically. A Molecular Network approach was used to highlight the different chemical classes characterizing the leaves of five Aloe species: Aloe macra, Aloe vera, Aloe tormentorii, Aloe ferox and Aloe purpurea. Aloe macra, A. tormentorii and A. purpurea are endemic from the Mascarene Islands comprising Reunion, Mauritius and Rodrigues. UHPLC-MS/MS analysis followed by a dereplication process allowed the characterization of 93 metabolites. The newly developed MolNotator algorithm was used as a tool for molecular networking and allowed a better exploration of the Aloe metabolome chemodiversity. The five species appeared to be rich in polyphenols (anthracene derivatives, flavonoids, phenolic acids). Therefore, total phenolic content and antioxidant activity of the five species were evaluated, and a DPPH-On-Line-HPLC assay was used to determine the metabolites responsible for the radical scavenging activity. The use of computational tools allowed a better description of the chemotaxonomy of five Aloe species, which showed differences in their metabolite composition, both qualitative and quantitative. Moreover, the molecular network approach allowed the identification of metabolites responsible for the antioxidant activity.

Project description:Several different mechanisms have been proposed to explain the possible role of cranberries, cranberry juice, and cranberry extracts in inhibiting bacterial growth. In this report, we showed that Escherichia coli showed slower growth rate in response to the presence of cranberry juice in the growth media. By compareing the global transcript profiles, significant modulation of several genes of E. coli grown in LB broth with 10% cranberry juice were identified and provided identification of the potential mechanisms involved in the inhibitory effects of cranberry juice. The results presented clearly demonstrate that the inhibitory effect on bacterial growth observed in the presence of cranberry juice/extracts is primarily a result of the iron chelation capacity of PACs and direct disruption of metabolic enzymes. The results are discussed with a focus on the genes associated with iron chelation capability. Keywords: growth inhibition of cranberry juice

Project description:In this study, we investigated the effects of organic vegetable juice supplementation on modulating the microbial community, and how its consumption ameliorates blood lipid profiles in diet-induced obese mice. Here, we analyzed the effect of organic vegetable juice on the microbial community and fatty acid synthesis via animal experiments using diet-induced obese mice and continuous colon simulation system. Organic vegetable juice supplement influenced intestinal bacterial composition from phylum to genus level, including decreased Proteobacteria in the ascending colon in the phylum. At the family level, Akkermansia which are associated with obesity, were significantly augmented in the transverse colon and descending colon compared to the control juice group. In addition, treatment with organic vegetable juice affected predicted lipid metabolism function genes related to lipid synthesis. Organic vegetable juice consumption did not have a significant effect on weight loss but helped reduce epididymis fat tissue and adipocytes. Additionally, blood lipid profiles, such as triglyceride, high-density lipoprotein, and glucose, were improved in the organic vegetable juice-fed group. Expression levels of genes related to lipid synthesis, including SREBP-1, PPARγ, C/EBPα, and Fas, were significantly decreased. Analysis of antioxidant markers, including 8-OHdG and MDA, in the vegetable juice group, indicated that blood lipid profiles were improved by the antioxidant effect. These results suggest that organic vegetable juice supplementation may modulate gut microbial community and reduce the potential role of hyperlipidemia in diet-obese mice.

Project description:During ripening of fruits stored under low temperatures, a number of physiological alterations which are manifested in a reduction of juice content take place, resulting in the apparition of woolly fruits. Modifications in cell wall structure during the ripening process are proposed to be key to determine the decreasing of juice content in woolly fruits. Under the assumption that changes in relative abundance of genes related to cell wall metabolism would be involved in woolliness development, in this work we present an analysis of the expression of multiple genes, which serves as an approximation to uncover the mechanisms behind this physiological alteration. The expression of 847 genes was examined using macroarrays hybridizations. Membranes were hybridized with 32P-labeled cDNAs synthesized from mRNAs of juice and woolly peaches. The results showed that 67.5% of the clones (n = 573) fulfilled all filter criteria and they were selected for sequence analysis. Our analysis indicate that 45% of transcripts which present a consistent expression level in all biological replicates are activated exclusively in juice condition, and only 15% in woolly fruits. In the resting 40% (transcripts common to both conditions,) only 5% presents an abundance increase in woolly samples. Keywords: Analysis of physiological disorder in peaches

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.
