Project description:<p>Gut microbiota modulation by a probiotic is a novel therapy for hypercholesterolemia mitigation. This study initially investigated the potential hypocholesterolemic effect of Bacillus sp. DU-106 in hypercholesterolemic rats and explored its potential relation with gut microbiota. Sprague-Dawley rats received a high-fat diet, or a high-fat diet supplemented with 7.5 × 10<sup>9</sup> and 1.5 × 10<sup>10</sup> CFU/kg bw/day Bacillus sp. DU-106 (low-dose and high-dose groups). At the end of 9 weeks, Bacillus sp. DU-106 treatment significantly decreased the body weight, liver index, and total cholesterol. 16S rRNA sequencing showed that Bacillus sp. DU-106 intervention significantly increased bacterial richness and particularly increased the genus abundance of Turicibacter, Acinetobacter, Brevundimonas, and Bacillus and significantly decreased the abundance of Ralstonia. Metabolomic data further indicated that the supplementation of Bacillus sp. DU-106 remarkably changed the gut metabolic profiles of hypercholesterolemic rats and, in particular, elevated the metabolites of indole-3-acetate, methylsuccinic acid, creatine, glutamic acid, threonine, lysine, ascorbic acid, and pyridoxamine. Spearman's correlation analysis showed the close relation between the different genera and metabolites. In conclusion, Bacillus sp. DU-106 supplement ameliorated high-fat diet-induced hypercholesterolemia and showed potential probiotic benefits for the intestine.</p><p><strong>KEY POINTS:</strong> • A novel potential probiotic Bacillus sp. DU-106 ameliorated hypercholesterolemia in rats. • Bacillus sp. DU-106 supplement regulated gut microbiome structure and richness. • Bacillus sp. DU-106 supplement changed metabolic profiles in high-fat diet rats. • Significant correlations were observed between differential genera and metabolites.</p>

Project description:The alkaliphilic halotolerant bacterium Bacillus sp. N16-5 often faces salt stress in its natural habitats. One-color microarrays was used to investigate transcriptome expression profiles of Bacillus sp. N16-5 adaptation reactions to prolonged grown at different salinities (0%, 2%, 8% and 15% NaCl) and the initial reaction to suddenly alter salinity from 0% to 8% NaCl.

One-color microarrays was used to investigate transcriptome expression profiles of Bacillus sp. N16-5 adaptation reactions to prolonged grown at different salinities (0%, 2%, 8% and 15% NaCl) and the initial reaction to suddenly alter salinity from 0% to 8% NaCl. Salt induced gene expression was measured when culture was grown on different salinities (0%, 2%, 8% and 15% NaCl) to mid-logarithmic phase. And salt induced gene expression was also measured at 0 min, 10 min, 30 min, 60min, 120min after a sudden change salinity from 0% to 8% NaCl.

Project description:Alkaline hemicellulytic bacteria Bacillus sp. N16-5 has abroad substrate spectrum and exhibits great growth ability on complex carbohydrates. In order to get insight into its carbohydrate utilization mechanism, global transcriptional profiles were separately determined for growth on glucose, fructose, mannose, galactose, arabinose, xylose, galactomannan, xylan, pectin and carboxymethyl cellulose by using one-color microarrays.

Project description:Bacillus sp. DU-106, a newly isolated member of Bacillus cereus group, exhibits the predominant ability to produce L-lactic acid. The probiotic potency of test strain revealed its survivability at acidic pH, bile salts and viability in simulated gastric juice in vitro. The acute oral toxicity test indicated its no toxicity to laboratory mice in vivo. We further determined the complete genome of strain DU-106 to understand genetic basis as a potential probiotic. It has a circular chromosome and three plasmids for a total genome 5,758,208 bp in size with a G + C content of 35.10%. Genes associated with lactate synthesis were found in the DU-106 genome. We also annotated various stress-related, bile salt resistance, and adhesion-related domains in this strain, which likely provide support in exerting probiotic action by enabling adhesion to host epithelial cells and survival under gastrointestinal tract. Moreover, strain DU-106 genome lacks the virulence genes encodes cereulide synthetase, enterotoxin FM, and cytotoxin K. These phenotypic and genomic probiotic potencies facilitate its potential candidate as probiotic starter in food industry.
