The Bacillus subtilis sigI gene, which is a member of the class VI heat shock genes of the B. subtilis heat shock stimulon, encodes an alternative sigma factor whose regulon is poorly defined. In this study, by using a binary vector system, we showed that B. subtilis SigI could drive expression of a transcriptional fusion between the sigI regulatory region from Bacillus licheniformis, Bacillus ...

Bacillus subtilis SC-8 is a Gram-positive bacterium displaying narrow antagonistic activity for the Bacillus cereus group. B. subtilis SC-8 was isolated from Korean traditional fermented-soybean food. Here we report the draft genome sequence of B. subtilis SC-8, including biosynthetic genes for antibiotics that may have beneficial effects for control of food-borne pathogens.

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.

Bacillus subtilis ATCC 6051a (=KCTC 1028), which is less domesticated than strain 168, is widely used for the secretory expression of industrial enzymes. Herein, we present the complete genome sequence of the Bacillus subtilis strain ATCC 6051a.

the goal of this research was to isolate and identify the thermostable alkaline protease producing bacteria among several native iranian microorganisms. at the end of screening program, a bacillus subtilis bp-36 strain producing thermophilic alkaline protease was isolated from a hot spring in ardebil province. the target enzyme was purified using a one-step aqueous two-phase systems (atps) prot...

conclusions b. subtilis entrapped in beads was able to preserve its viability and produce biosurfactants as secondary metabolites. therefore, this method could be applied as a continuous culture system of biosurfactant production. methods alginate and bacterial solutions were mixed by stirring to obtain a uniform mixture and added by drops into cacl2 solution to form spherical beads. the spheri...

Azoreductases have been characterized as enzymes that can decolorize azo dyes by reducing azo groups. In this study, genes encoding proteins having homology with the azoreductase gene of Bacillus sp. OY1-2 were obtained from Bacillus subtilis ATCC6633, B. subtilis ISW1214, and Geobacillus stearotherophilus IFO13737 by polymerase chain reaction. All three genes encoded proteins with 174 amino ac...

Genome features of the Bacillus cereus group genomes (representative strains of Bacillus cereus, Bacillus anthracis and Bacillus thuringiensis sub spp. israelensis) were analyzed and compared with the Bacillus subtilis genome. A core set of 1381 protein families among the four Bacillus genomes, with an additional set of 933 families common to the B. cereus group, was identified. Differences in ...

BACKGROUND Bacillus subtilis are opportunistic, spore forming bacteria, common soil inhabitants. A resistant spore allows bacteria to endure extreme conditions of heat and desiccation in the environments promotes their survival in many instances, even in environments like hospitals. OBJECTIVES This paper purposes to find out the incidence of Bacillus subtilis from various sources at Azadi Tea...

Biosurfactants are amphiphilic compounds produced by various bacteria and fungi which reduce surface and interfacial tension. Oil contaminated soil were collected from four different automobile shop in Mayiladuthurai, Tamilnadu, India. Bacillus subtilis and Pseudomonas aeruginosa were isolated and identified from these four samples and these were screened for biosurfactants production using veg...
