The Gram-positive bacterium Bacillus subtilis is widely used for studies of cellular and molecular processes. We announce the complete genomic sequences of strain AG174, our stock of the commonly used strain JH642, and strain AG1839, a derivative that contains a mutation in the replication initiation gene dnaB and a linked Tn917.

Bacillus subtilis PS216, a strain isolated in Slovenia, has been sequenced. PS216 is transformable and forms robust biofilms, making it useful for the study of competence regulation in an undomesticated bacterium.

Many different systems of bacterial interactions have been described. However, relatively few studies have explored how interactions between different microorganisms might influence bacterial development. To explore such interspecies interactions, we focused on Bacillus subtilis, which characteristically develops into matrix-producing cannibals before entering sporulation. We investigated wheth...

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.

halophilic bacteria grow over a wide range of salt concentrations. in this study we aimed to isolate and screen out the halophilic bacteria and to determine their activity for production of the bioactive compounds. a total of 50 water, sediments and soil samples were collected from maharlu salt lake in southern region of fars-iran and subjected for isolation of the bioactive compound producing ...

the probiotic effects of two gram positive bacteria, bacillus subtilis and bacillus licheniformis, were examined on growth performance, body composition and survival rate of artemia urmiana. three diets containing 102 (t1), 104 (t2), 106 (t3) cfu of probiotics g feed-1 and a control diet (c) without probiotic were used through a completely randomized design (each with three replicates). the use...

DNA replication in bacteria is carried out by a multiprotein complex, which is thought to contain only one essential DNA polymerase, specified by the dnaE gene in Escherichia coli and the polC gene in Bacillus subtilis. Bacillus subtilis genome analysis has revealed another DNA polymerase gene, dnaE(BS), which is homologous to dnaE. We show that, in B. subtilis, dnaE(BS) is essential for cell v...

Biosorption can be an effective technique for the treatment of heavy metal bearing waste water resulting from humuns and industrial activities. Several gram positive and gram negative bacteria have the ability to remove the heavy metals and there by making water contaminant free. It has been reported that attenuated bacterial biomass have greater biosorption capability than viable cells. In the...

The antibacterial effect of thyme, peppermint, sage, black pepper and garlic hydrosols, widely used in food products as drinks and food additives, were tested for their inhibitory effects against Bacillus subtilis and Salmonella enteritidis. Single and combined hydrosols of previous common herbs were used to evaluate in vitro the antibacterial activity against these pathogenic bacteria. The obt...

Intestinal bacteria drive the formation of lymphoid tissues, and in rabbit, bacteria also promote development of the preimmune Ab repertoire and positive selection of B cells in GALT. Previous studies indicated that Bacillus subtilis promotes B cell follicle formation in GALT, and we investigated the mechanism by which B. subtilis stimulates B cells. We found that spores of B. subtilis and othe...
