Spore production by Bacillus stearothermophilus.
Methods reported in the literature for the production of spores by Bacillus stearothermophilus require from 4 to 14 days of incubation (N. Finley and M. L. Fields, Appl. Microbiol. 10:231, 1962; D. I-C. Wang, J. Scharer, and A. E. Humphrey, Appl. Microbiol. 12:451, 1964; L. L. Campbell, C. M. Richards, and E. E. Sniff, p. 55, in L. L. Campbell and H. 0. Halvorson [ed.], Spores III, American Soc...
متن کاملComparative characterization of silver nanoparticles synthesized by spore extract of Bacillus subtilis and Geobacillus stearothermophilus
Objective(s): Silver nanostructures have gathered remarkable attention due to their applications in diversefields. Researchers have recently demonstrated that bacterial spores are capable of reducing silver ions toelemental silver leading to formation of nanoparticles.Materials and Methods: In this study, spores of Bacillus subtilis and Geobacillus stearothermophilus wereemployed to produce sil...
متن کاملEnvironmental Stresses on Spore Populations of Bacillus Stearothermophilus.
Heat-shocking spores at 110 C in 20% sucrose solutions decreased the percentage of the rough variant in a mixed population (rough and smooth variants) of strain M. Heat-shocking spores of the rough variant of strain NCA 1518 in 20% sucrose produced a decline in the number which germinated, whereas the smooth variant of strain NCA 1518 increased in the number which germinated. By the use of phas...
متن کاملFactors affecting spore formation in a Candida albicans strain.
Growth and spore formation of Candida albicans Y-45 was enhanced by low oxygen tension. Mycelium and chlamydospores were abundantly found on rice infusion-Tween 80 agar within 48 to 96 h, and abundant chlamdospore production occurred most rapidly under reduced oxygen tension and incubation at 30 degrees C. Zn, Mg, Mn, anf Fe were tested for their ability to promote filamentation in C. albicans ...
متن کاملBacillus stearothermophilus. II. Certain factors affecting amylase production on some undefined media.
Imsenecki and co-workers (1942, 1944) and Stark and Tetrault (1952) described some cultural conditions influencing the breakdown of starch by aerobic, stenothermophilic bacteria. The former investigators found that a 5 per cent potato decoction was superior to decoctions of wheat, corn and other products in ability to promote amylase formation. The latter investigators found that a 1.5 per cent...
