Dormant spores of Bacillus species lack ATP and NADH and contain notable levels of only a few other common low mol wt energy reserves, including 3-phosphoglyceric acid (3PGA), and glutamic acid. Recently, Bacillus subtilis spores were reported to contain ~ 30 μmol of L-malate/g dry wt, which also could serve as an energy reserve. In present work, L-malate levels were determined in the core of d...

In this study, we have identified a bacterium that can inhibit the growth of Staphylococcus aureus, and further analyzed its antibacterial activity and other biological characteristics and laid the foundation for its future application. Through isolation and culture of the unknown bacteria, the culture characteristics, morphology observation, biochemical test, preliminary antibacterial test, 16...

sesame oil cake (ssc) was bio-processed through solid state fermentation (ssf) under optimized conditions by a phytase-producing fish gut bacterium, bacillus subtilis subsp. subtilis (jx292128). ssf significantly reduced anti-nutritional factors (e.g., phytic acid, tannins and trypsin inhibitor) and crude fibre, while enhanced free amino acids, fatty acids and different minerals. phytase product...

We report here the 4.092-Mb high-quality draft genome assembly of a newly isolated poly-γ-glutamic acid-producing strain, Bacillus subtilis Ia1a. The genome sequence is considered a critical tool to facilitate the engineering of improved production strains. Exopolysaccharides and many industrially important enzymes can be produced by this new strain utilizing different carbon sources.

Bacillus subtilis is a ubiquitous Gram-positive model organism. Here, we describe the complete genome of B. subtilus myophage Grass. Aside from genes encoding core proteins pertinent to the life cycle of the phage, Grass has several interesting features, including an FtsK/SpoIIIE protein.

Bacillus subtilis strain NKYL29 is an antimicrobial-peptide-producing strain isolated from the soil of Ranzhuang Tunnel in Hebei Province, China. Here, we present the draft genome of this strain, which provides the genetic basis for application of the antimicrobial peptide.

A Bacillus subtilis culture incubated anaerobically in nitrate-containing medium lost viability during the first 3 days but recovered thereafter. A flavohemoglobin mutant showed very poor survival under these conditions unless the cells were prevented from carrying out nitrate respiration.

Expression of the Bacillus subtilis or Bacillus amyloliquefaciens sacB gene in the presence of sucrose is lethal for a variety of bacteria. Sucrose-induced lethality can be used to select for inactivation of sacB by insertion of heterologous DNA in sensitive bacteria. This procedure has not been applicable to B. subtilis heretofore because expression of wild-type sacB is not detrimental to B. s...

A polymerase chain reaction (PCR) assay was developed for discrimination of Bacillus subtilis from other members of B. subtilis group as well as rapid identification from environmental samples. Primers ENIF and EN1R from endoglucanase gene were used to amplify a1311 bp DNA fragment. The specificity of the primers was tested with seven reference strains and 28 locally isolated strains of endoglu...
