BACKGROUND In this study, we attempted to screen and investigate antibacterial activity of Bacillus species, which were isolated from conjunctiva, against other eyes pathogens. METHODS To examine predominant isolates of Bacillus subtilis, B. pumilus, B. cereus and B. mojevensis, isolated from conjunctiva for their antimicrobial activity against indicator microorganisms as Micrococcus luteus, ...

Transcriptional profiling highlighted a subset of genes encoding putative multidrug transporters in the pathogen Bacillus cereus that were up-regulated during stress produced by bile salts. One of these multidrug transporters (BC4707) was selected for investigation. Functional characterization of the BC4707 protein in Escherichia coli revealed a role in the energized efflux of xenobiotics. Phen...

Aims: To study the biosorption of lead ions from solution using Bacillus cereus isolated from industrial effluents collected from Peenya industrial area, Bangalore, India and to determine the optimum conditions for biosorption. Study design: Experimental study. Place and Duration of Study: Department of Microbiology and Biotechnology, Bangalore University, Bangalore, Karnataka, India, between O...

Three species of Bacillus were evaluated as potential surrogates for Bacillus anthracis for determining the sporicidal activity of chlorination as commonly used in drinking water treatment. Spores of Bacillus thuringiensis subsp. israelensis were found to be an appropriate surrogate for spores of B. anthracis for use in chlorine inactivation studies.

Bacteria from the Bacillus cereus group exhibit genetic and physiological diversity through different ecotypes. Here, we present the draft genome sequences of 20 bacterial strains belonging to the contrasted psychrotolerant and thermotolerant ecotypes.

A total of 119 Bacillus thuringiensis strains (83 type strains and 26 native isolates), as well as five B. cereus group species, were analyzed by repetitive extragenic palindromic sequence-based PCR analysis (Rep-PCR) fingerprinting. Primers Bc-REP-1 and Bc-REP-2 were specifically designed according to an extragenic 26-bp repeated sequence found in the six B. cereus group genomes reported. A to...

Bacillus anthracis, Bacillus cereus, and Bacillus thuringiensis (Bt) are spore-forming members of the Bacillus cereus group. Spores of B. cereus group species are encircled by exosporium, which is composed of an external hair-like nap and a paracrystalline basal layer. Despite the extensive studies on the structure of the exosporium-related proteins, little is known about the transcription and ...

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.

A microtiter procedure for the quantitation of Bacillus cereus hemolysin is described.

We constructed a promoter-trap plasmid, pAD123, for Bacillus cereus. This plasmid contains a promoterless gene that encodes a mutant version of the green fluorescent protein, GFPmut3a, that is optimized for fluorescence-activated cell sorting [Cormack, B.P., Valdivia, R.H., Falkow, S., 1996. FACS-optimized mutants of the green fluorescent protein (GFP). Gene 173, 33-38.]. The plasmid replicates...
