Bacillus subtilis spores germinate in the chicken gastrointestinal tract.
A number of poultry probiotics contain bacterial spores. In this study, orally administered spores of Bacillus subtilis germinated in the gastrointestinal (GI) tracts of chicks. Furthermore, 20 h after spores were administered, vegetative cells outnumbered spores throughout the GI tract. This demonstrates that spore-based probiotics may function in this host through metabolically active mechani...
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 کاملResporulation of outgrowing Bacillus subtilis spores.
Germinated spores of Bacillus subtilis were incubated in outgrowth medium and tested periodically for capacity to sporulate when suspended in sporulation medium. Concurrent measurements were made of deoxyribonucleic acid (DNA) content and numbers of cell division septa and nucleoids. Sporulation potential is shown to reach a peak at about 110 min at which time the chromosomes are probably well ...
متن کاملSporulenes, Heptaprenyl Metabolites from Bacillus subtilis Spores
Sporulene, a C 35-terpenoid hydrocarbon with an unusual pentacyclic structure, is produced by Bacillus subtilis during sporulation.
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, ...
