Here we announce a 3.0-Mb assembly of the Bacillus coagulans Hammer strain, which is the type strain of the species within the genus Bacillus. Genomic analyses based on the sequence may provide insights into the phylogeny of the species and help to elucidate characteristics of the poorly studied strains of Bacillus coagulans.
antimicrobial activity of plant extracts in traditional medicine on bacteria and fungi has been identified. medicinal plants have been used since ancient times as a food coloring and flavoring agents. also, plant extracts have been used for the prevention of diseases caused by food borne pathogens. with the use of active packaging that can interact with the environment and product, increased sh...
A multi locus sequence analysis (MLSA approach) was studied on the Bacillus genus, or subtilis species complex for specific, including 08 strains from four (B. subtilis, B. pumilus, licheniformis and amyloliquefaciens) were provided by Biotechnology Center of Ho Chi Minh City. The research based sequences 16S rRNA genes, concatenation five protein-coding housekeeping genes: glpF, pta, purH, pyc...
New 1,3,4-thiadiazole, 5a-e, and 1,2,4-triazolecompounds 6a-c, containing a D,L-methionine moiety were synthesized by intramolecular cyclization of 1,4-disubstituted thiosemicarbazides 4a-e in acid and alkaline media, respectively. The potential antimicrobial effects of the synthesized compounds were investigated using the Staphylococcus aureus ATCC 25923, Bacillus antracis ATCC 8705, Bacillus ...
A new series of novel 3-azabicyclic spiro 1',2',4'-triazolidin-3'-thiones 15-21 catalyzed by potassium superoxide under microwave irradiation have been synthesized and studied for their in vitro microbiological evaluation on clinically isolated bacterial strains namely Micrococcus luteus, Bacillus subtilis, Bacillus cereus, Pseudomonas aeuroginosa and fungal strains namely Aspergillus niger, Ca...
We report the isolation, cloning and expression, in Bacillus subtilis, of the gene coding for thermolysin, a thermostable metalloprotease which is produced by Bacillus thermoproteolyticus Rokko. The nucleotide sequence has revealed that, like neutral proteases produced by other members of the Bacillus species, thermolysin is probably produced as a preproenzyme carrying a typical N-terminal memb...
Bacillus cereus is a gram positive bacterium with sporulation capacity. Here, we report the complete genome sequence of two native B. cereus strains (#25 and #29) isolated from intestinal tract of the crab Ucides sp. from Pacoti River in the State of Ceará, Brazil. The findings of this study might increase the molecular information for Bacillus strains. The data can be used in comparative analy...
Background and purpose: Dairy products often associated with problems such as short shelf life and poor hygiene control. A novel approach is to utilize bacteriocin or bacteriocin producer strains, to control undesirable micro flora as Listeria monocytogenes and Bacillus cereus in foods. Hence, we studied the effect of nisin like producing Lactococcus lactis against Listeria monocytogenes and ...
Silica gel thin-layer chromatography was employed to detect lecithinase activity induced from bacterial resting cell preparations induced from bacterial resting cell preparations incubated at 37 C for 4 h in the presence of purified egg yolk lecithin. Bacillus subtilis, Bacillus cereus, Serratia marcescens, and Pseudomonas aeruginosa hydrolyzed lecithin with the formation of free fatty acids as...
The ability to distinguish microbial pathogens from closely related but nonpathogenic strains is key to understanding the population biology of these organisms. In this regard, Bacillus anthracis, the bacterium that causes inhalational anthrax, is of interest because it is closely related and often difficult to distinguish from other members of the B. cereus group that can cause diverse disease...
