Bacillus licheniformis is an important bacterium that has been used extensively for large-scale industrial production of exoenzymes and peptide antibiotics. B. licheniformis WX-02 produces poly-gamma-glutamate increasingly when fermented under stress conditions. Here its genome sequence (4,270,104 bp, with G+C content of 46.06%), which comprises a circular chromosome, is announced.

Bacillus licheniformis is a Gram-positive, endospore-forming, saprophytic organism that occurs in plant and soil (Veith et al., 2004). A taxonomical approach shows that it is closely related to Bacillus subtilis (Lapidus et al., 2002; Xu and Côte, 2003; Rey et al., 2004). Generally, most bacilli are predominantly aerobic; however, B. licheniformis is a facultative anaerobe compared to other bac...

The present study is focused on the improvement of Bacillus licheniformis through random mutagenesis to obtain mutant having enhanced production of bacitracin. Many isolates of Bacillus licheniformis were isolated and the isolate GP-40 produced maximum bacitracin production (16±0.72 IU/mL). Treatment of Bacillus licheniformis GP-40 with ultraviolet (UV) radiations increased bacitracin productio...

In the facultatively anaerobic bacterium Bacillus licheniformis a gene encoding a protein of the fumarate nitrate reductase family of transcriptional regulators (Fnr) was isolated. Unlike Fnr proteins from gram-negative bacteria, but like Fnr from Bacillus subtilis, the protein contained a C-terminal cluster of cysteine residues. Unlike in Fnr from B. subtilis, this cluster (Cys226-X2-Cys229-X4...

Four hundred bacterial isolates were isolated from rhizosphere of some plants collected from Egypt and screened for production of chitinase enzyme. Only four isolates designated MS1, MS2, MS3 and MS4 were the most potent chitinolytic bacterial species. SDS-PAGE analysis of vegetative and sporulated cells of the four isolates revealed that the protein profile of the four isolates were different ...

A phage, designated CP-51, that carries out generalized transduction in Bacillus cereus and B. anthracis, has recently been isolated from soil. Transducing phages for members of the genus Bacillus have been described previously for B. subtilis and B. licheniformis (2-6). Those that have been best characterized are PBS-1 for B. subtilis (4) and SP-10 and SP-15 for both B. subtilis and B. licheni...

Toxin-producing isolates of Bacillus licheniformis were obtained from foods involved in food poisoning incidents, from raw milk, and from industrially produced baby food. The toxin detection method, based on the inhibition of boar spermatozoan motility, has been shown previously to be a sensitive assay for the emetic toxin of Bacillus cereus, cereulide. Cell extracts of the toxigenic B. licheni...

In this study, we characterized the heat shock stimulon of the important industrial microorganism Bacillus licheniformis using DNA microarrays. While sharing a high degree of homology with the closely related model organism Bacillus subtilis, the heat shock stimulon of B. licheniformis exhibited several novel and unexpected features. Most notably, heat shock in B. licheniformis resulted in decr...
