conclusions this study indicated that some bacillus species have the potential to produce antimicrobial compounds which can be used to control microbial infections. results the identified bacillus species included b. cereus (86.6%), b. subtilis (6.6%), b. thuringiensis (3.3%), and b. pumilus (3.3%). evaluation of the antimicrobial activity of the extracted compounds was carried out against five...

The complete sequencing and annotation of the genomes of industrially-important Bacillus species has enhanced our understanding of their properties, and allowed advances in genetic manipulations in other Bacillus species. Post-genomic studies require simple and highly efficient tools to enable genetic manipulation. Here, we summarize the recent progress in genetic engineering strategies for Bac...

Bacillus represents microbes of high economic, medical and biodefense importance. Bacillus strain identification based on 16S rRNA sequence analyses is invariably limited to species level. Secondly, certain discrepancies exist in the segregation of Bacillus subtilis strains. In the RDP/NCBI databases, out of a total of 2611 individual 16S rDNA sequences belonging to the 175 different species of...

For this study pneumonic lung tissue and tracheal swabs were collected from sheep, goat and cattle slaughtered at Elphora abattoir. From the total of 170 bacterial isolates from sheep lung tissue, 10.6% Bacillus species, 14.7% Mannheimia haemolytica and 42.4% Staphylococcus species were isolated aerobically. The tracheal cultures also indicated that 5.8% were Enterobacter species, 13% were Bibe...

Nine strains of Bacillus popilliae and Bacillus lentimorbus KLN2 contain N6-methyladenine in GATC sequences, as determined by using the restriction enzymes MboI and DpnI. Among eight other Bacillus species examined, all, except one strain of Bacillus brevis (ATCC 9999), lacked adenine methylation in GATC. A methylase with Escherichia coli dcm site specificity was not present in any of the Bacil...

Here, we report the draft genome sequences of the type strains of three cellulolytic or hemicellulolytic alkaliphilic Bacillus species: Bacillus wakoensis, Bacillus akibai, and Bacillus hemicellulosilyticus. The genome information for these three strains will be useful for studies of alkaliphilic Bacillus species, their evolution, and biotechnological applications for their enzymes.

The nucleotide sequences of the 3' end of the 16S rDNA and the 16S-23S internal transcribed spacer (ITS) of 40 Bacillaceae species were determined. These included 21 Bacillus, 9 Paenibacillus, 6 Brevibacillus, 2 Geobacillus, 1 Marinibacillus and 1 Virgibacillus species. Comparative sequence analysis of a 220 bp region covering a highly conserved 150 bp sequence located at the 3' end of the 16S ...

The present study emphasizes the diversity assessment of marine Bacillus species with special reference to biosurfactant production, respective gene expression, and discrimination among Bacillus licheniformis and Bacillus subtilis. Among the 200 individual species of eastern coastal plain of Tamil Nadu screened, five biosurfactant producing potential bacterial species with entirely different mo...

Bacillus spore surface morphology was imaged with atomic force microscopy (AFM) to determine if characteristic surface features could be used to distinguish between four closely related species; Bacillus anthracis Sterne strain, Bacillus thuringiensis var. kurstaki, Bacillus cereus strain 569, and Bacillus globigii var. niger. AFM surface height images showed an irregular topography across the ...

Forty-seven strains representing 14 different Bacillus species isolated from clinical and food samples were grown in reconstituted infant milk formulae (IMF) and subsequently assessed for adherence to, invasion of, and cytotoxicity toward HEp-2 and Caco-2 cells. Cell-free supernatant fluids from 38 strains (81%) were shown to be cytotoxic, 43 strains (91%) adhered to the test cell lines, and 23...
