Selective catalytic oxidation of organosulfur compounds with tert-butyl hydroperoxide.
Rates and selectivities for the oxidation of various organosulfur compounds with tert-butyl hydroperoxide were measured on CoAPO-5 (APO = aluminophosphate; Co/P = 0.05), Co/H-Y (Co/Al = 0.15), and MoO(x)/Al2O3 (15 % wt MoO3). Rates increased with increasing electron density at the sulfur atom (methyl phenyl sulfide>diphenyl sulfide>4-methyldibenzothiophene>2,5-dimethyl thiophene). Rates (per me...
متن کاملIncreases in cytosolic calcium ion concentration can be dissociated from the killing of cultured hepatocytes by tert-butyl hydroperoxide.
Digital imaging fluorescence microscopy was used to study the effect of tert-butyl hydroperoxide (TBHP) on the cytosolic free calcium concentration ([Ca2+]i) of single rat hepatocytes in primary culture. Within minutes of the addition of TBHP, individual hepatocytes displayed one or more peaks of increased [Ca2+]i that promptly returned to the prestimulation level. This was followed by a slower...
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...
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 ...
