Project description:The complete genome sequence of Bacillus subtilis T30 was determined by SMRT sequencing. The entire genome contains 4,138 predicted genes. The genome carries one intact prophage sequence (37.4 kb) similar to Bacillus phage SPBc2 and one incomplete prophage genome of 39.9 kb similar to Bacillus phage phi105.

Project description:Bacillus subtilis 3NA reaches high cell densities during fed-batch fermentation and is an interesting target for further optimization as a production strain. Here, we announce the full genome of B. subtilis 3NA. The presence of specific Bacillus subtilis 168 and W23 genetic features suggests that 3NA is a hybrid of these strains.

Project description:We sequenced four strains of Bacillus subtilis and the type strains for two closely related species, Bacillus vallismortis and Bacillus mojavensis. We report the high-quality Sanger genome sequences of B. subtilis subspecies subtilis RO-NN-1 and AUSI98, B. subtilis subspecies spizizenii TU-B-10(T) and DV1-B-1, Bacillus mojavensis RO-H-1(T), and Bacillus vallismortis DV1-F-3(T).

Project description:Bacillus subtilis ?6 is a genome-reduced strain that was cured from six prophages and AT-rich islands. This strain is of great interest for biotechnological applications. Here, we announce the full-genome sequence of this strain. Interestingly, the conjugative element ICEBs1 has most likely undergone self-excision in B. subtilis ?6.

Project description:Soybeans fermented by Bacillus subtilis BJ3-2 exhibits strong ammonia taste in medium temperature below 37℃ and prominent soy sauce-like aroma moderate temperatures above 45℃. The transcriptome sequencing of Bacillus subtilis BJ3-2 (incubating at 37°C and 45°C) has been completed, screening of differentially expressed genes (DEGs) through data analysis, and analyzing their metabolic pathways, laying a foundation for exploring the regulatory mechanism of soy sauce-like aroma formation.

Project description:BACKGROUND: Bacillus subtilis natto is closely related to the laboratory standard strain B. subtilis Marburg 168, and functions as a starter for the production of the traditional Japanese food "natto" made from soybeans. Although re-sequencing whole genomes of several laboratory domesticated B. subtilis 168 derivatives has already been attempted using short read sequencing data, the assembly of the whole genome sequence of a closely related strain, B. subtilis natto, from very short read data is more challenging, particularly with our aim to assemble one fully connected scaffold from short reads around 35 bp in length. RESULTS: We applied a comparative genome assembly method, which combines de novo assembly and reference guided assembly, to one of the B. subtilis natto strains. We successfully assembled 28 scaffolds and managed to avoid substantial fragmentation. Completion of the assembly through long PCR experiments resulted in one connected scaffold for B. subtilis natto. Based on the assembled genome sequence, our orthologous gene analysis between natto BEST195 and Marburg 168 revealed that 82.4% of 4375 predicted genes in BEST195 are one-to-one orthologous to genes in 168, with two genes in-paralog, 3.2% are deleted in 168, 14.3% are inserted in BEST195, and 5.9% of genes present in 168 are deleted in BEST195. The natto genome contains the same alleles in the promoter region of degQ and the coding region of swrAA as the wild strain, RO-FF-1. These are specific for gamma-PGA production ability, which is related to natto production. Further, the B. subtilis natto strain completely lacked a polyketide synthesis operon, disrupted the plipastatin production operon, and possesses previously unidentified transposases. CONCLUSIONS: The determination of the whole genome sequence of Bacillus subtilis natto provided detailed analyses of a set of genes related to natto production, demonstrating the number and locations of insertion sequences that B. subtilis natto harbors but B. subtilis 168 lacks. Multiple genome-level comparisons among five closely related Bacillus species were also carried out. The determined genome sequence of B. subtilis natto and gene annotations are available from the Natto genome browser http://natto-genome.org/.

Project description:Investigation of the kinetics of whole genome gene expression level changes in Bacillus subtilis NDmed strain during formation of submerged biofilm and pellicle. The Bacillus subtilis NDmed strain analyzed in this study is able to form thick and highly structured submerged biofilms as described in Bridier et al., (2011) The Spatial Architecture of Bacillus subtilis Biofilms Deciphered Using a Surface-Associated Model and In Situ Imaging. PLoS ONE 6(1):e16177. Overall design: A seven chip study using total RNA recovered from static cultures of Bacillus subtilis NDmed growing in TSB medium in 96-well microplates for different times after adhesion to the bottom of the wells. Each chip measures the expression level of 5,737 transcripts from Bacillus subtilis 168.

Project description:Bacillus subtilis mutants with high expression of the bacilysin operon ywfBCDEFG were isolated. Comparative genome sequencing analysis revealed that all of these mutants have a mutation in the scoC gene. The disruption of scoC by genetic engineering also resulted in increased expression of ywfBCDEFG. Primer extension and gel mobility shift analyses showed that the ScoC protein binds directly to the promoter region of ywfBCDEFG. Our results indicate that the transition state regulator ScoC, together with CodY and AbrB, negatively regulates bacilysin production in B. subtilis.
