Structural and genetic analysis of X-ray scattering by spores of Bacillus subtilis.
Dormant spores of Bacillus subtilis exhibit two prominent X-ray scattering peaks. These peaks persisted in spores lacking most alpha/beta-type small, acid-soluble protein or the CotE protein responsible for assembly of much spore coat protein, but they were absent from spores of strains lacking the late sporulation-specific transcription factor GerE.
متن کاملEnvironmental Persistence of Bacillus anthracis and Bacillus subtilis Spores
There is a lack of data for how the viability of biological agents may degrade over time in different environments. In this study, experiments were conducted to determine the persistence of Bacillus anthracis and Bacillus subtilis spores on outdoor materials with and without exposure to simulated sunlight, using ultraviolet (UV)-A/B radiation. Spores were inoculated onto glass, wood, concrete, ...
متن کاملEffects of Different Times of Glutaraldehyde 2% on Bacillus subtilis Spores (In Vitro)
Background: Due to the importance of disinfectant and sterilization of dental instruments, in total, 14%–28% of dentists, 13% of assistants, and 17% of healthcare workers (HCWs) have been subjected to the hepatitis B virus (HBV), and more than 200 healthcare providers (HCPs) pass away annually in the United States from HBV infection catched from their work place. ...
متن کاملResistance of Bacillus subtilis Spores to Inactivation
A statistical evaluation of viable count procedures utilized for obtaining treatment survival curve data for Bacillus subtilis NCTC 8236 spores is described. Within the various recovery conditions tested, incubation on nutrient agar containing 1% dextrose for 48 hr at 37 C was found to promote the highest count of viable spores surviving a variety of bactericidal treatments involving gamma irra...
متن کاملSpecific inhibition of outgrowth of Bacillus subtilis spores by novobiocin.
Spores of a Bacillus subtilis mutant temperature sensitive in deoxyribonucleic acid (DNA) replication proceeded through outgrowth at the nonpermissive temperature to the same extent as the wild-type parent spores. In contrast, the DNA synthesis inhibitor novobiocin completely prevented spore outgrowth while displaying a marginal effect on logarithmic growth during one generation time. Inhibitio...
