Reclassification of bioindicator strains Bacillus subtilis DSM 675 and Bacillus subtilis DSM 2277 as Bacillus atrophaeus.
On the basis of high DNA-DNA reassociation values and confirmatory automated RiboPrint analysis, two aerobic spore-forming strains hitherto allocated to Bacillus subtilis and used as bioindicators (DSM 675, hot-air sterilization control; DSM 2277, ethylene oxide sterilization control) are reclassified as Bacillus atrophaeus.
متن کاملInvestigation of the effect of biosurfactant of Bacillus subtilis against Staphylococcus strains biofilms
Background: Biosurfactants are compounds that are produced by different microorganisms and have an emulsifying property. This study aimed to investigate extractive biosurfactant from bacillus subtilis (PTCC1720) against the biofilms of Staphylococcus aureus (PTCC 1112), Staphylococcus saprophyticus (PTCC 1440) and Staphylococcus epidermidis (PTCC 1435). Materials and Methods: This study was con...
متن کاملBiochemical and cultural characteristics of "JK" coryneforms.
Antibiotic resistant coryneforms (group JK) have increasingly been reported as causes of serious sepsis in the immunosuppressed and in patients with implants. Their cultural and biochemical characteristics were examined in an attempt to provide a simple scheme for their recognition in the clinical laboratory. Their susceptibilities to a range of antimicrobials were determined, and an enriched s...
متن کاملRelationship of Bacillus subtilis clades associated with strains 168 and W23: a proposal for Bacillus subtilis subsp. subtilis subsp. nov. and Bacillus subtilis subsp. spizizenii subsp. nov.
Earlier phylogenetic studies based on the inferred DNA sequences of the polC, rpoB and gyrA genes suggested that strains of the species Bacillus subtilis formed two clusters, indicating the presence two closely related taxa; one contained the laboratory strain 168 and the other the laboratory strain W23. Significant sexual isolation was found between strain 168 and members of the group containi...
متن کاملConstruction and detection of bioluminescent strains of Bacillus subtilis.
Bioluminescence (lux) genes from Vibrio fischeri and V. harveyi were introduced into Bacillus subtilis on a plasmid vector and by chromosomal integration. The plasmid-bearing strain was highly luminescent and stable under antibiotic selection, but luminescence was lost in the absence of selection and following sporulation and germination. The chromosomally marked strains emitted less light but ...
