Resistance 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 کاملFormaldehyde gas inactivation of Bacillus anthracis, Bacillus subtilis, and Geobacillus stearothermophilus spores on indoor surface materials.
AIMS To evaluate the decontamination of Bacillus anthracis, Bacillus subtilis, and Geobacillus stearothermophilus spores on indoor surface materials using formaldehyde gas. METHODS AND RESULTS B. anthracis, B. subtilis, and G. stearothermophilus spores were dried on seven types of indoor surfaces and exposed to approx. 1100 ppm formaldehyde gas for 10 h. Formaldehyde exposure significantly de...
متن کاملThermal inactivation of aerosolized Bacillus subtilis var. niger spores.
A hot-air sterilizer capable of exposing airborne microorganisms to elevated temperatures with an almost instantaneous heating time was developed and evaluated. With this apparatus, aerosolized Bacillus subtilis var. niger spores were killed in about 0.02 sec when exposed to temperatures above 260 C. This is about 500 times faster than killing times reported by others. Extrapolation and compari...
متن کاملThermal inactivation characteristics of Bacillus subtilis spores at ultrahigh temperatures.
The thermal inactivation characteristics of Bacillus subtilis A spores suspended in skim milk with the use of large-scale ultrahigh temperature (UHT) processing equipment were investigated in terms of survival as measured with two plating media. Data on survival immediately after UHT treatments were recorded in temperature-survivor curves, time-survivor curves, and decimal reduction time (DRT) ...
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. ...
