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.

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:<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:BAC pool DNA hybridisation of barley to 44k Agilent microarrays. We have used two-channel Agilent expression microarrays to address thousands of gene sequences to individual BAC clones and contigs that form part of an emerging physical map of the large and unsequenced 5300 Mbp barley genome. By using two-colour processing, each array allows simultaneous co-hybridization of two independent BAC pools (SP), for which the data is analysed separately. As a general approach the method represents a cost-effective, highly parallel alternative to traditional gene-to-BAC addressing methods. By coupling the BAC address-data with gene-based genetic maps we were able to anchor thousands of BACs to the barley genetic map.

Project description:P. aeruginosa is the leading cause of death in patients with cystic fibrosis patients and one of the most problematic bacterial pathogens responsible for hospital-acquired infections. This pathogen has a high capacity to form biofilms on inert and living surfaces. This lifestyle allows it to persist in various hospital niches or on medical device which become vectors of contamination. Chronic infections are extremely complicated to eradicate due to the remarkable antimicrobial resistance of biofilms leading to a persistence in the tissue and an immune system exhaustion. It is therefore becoming essential to understand the mechanisms of biofilm formation to find new therapeutic targets in order to develop effective antibiofilm strategies. We previously identified in P. aeruginosa PA01 biofilms an accumulation of a hypothetical protein named PA3731 and its deletion impacted the biofilm formation. Similarly, to PspA, a protein from the well-known Psp system of E. coli, PA3731 is a has a predicted structure mostly helical, a PspA/IM30 domain and was accumulated during an osmotic shock. In P. aeruginosa genome, PA3731 appears to form a cluster with 3 genes (PA3732 to PA3729) that we named BAC system for “Biofilm Associated Cluster”. Here we worked on the PA14 strain and focus our study on PA14_16140, the PA3732 homologue. Using a ∆16140 mutant and phenotypic approach, we confirmed the role of the BAC system in the virulence and biofilm formation. We added supplementary genes coding the BAC system and demonstrate that altogether they form an operonic structure regulates by RpoN. We get further insight the role PA14_16140 by proteomic quantitative approach revealing an accumulation of the BAC system proteins in ∆16140 biofilms suggesting its regulatory role of the bac operon. Moreover, we present here the first crystallographic structure of PA14_16140. To summarise, according to our studies, and although further analysis is still required, this newly discovered operon appears composed firstly of its regulator and then of a homologous PspA.
