Alcohol-resistant sporulation mutants of Bacillus subtilis.
About 80% of Bacillus subtilis cells form spores when grown in nutrient broth. In medium containing various short-chain aliphatic alcohols, the frequency of sporulation was reduced to 0.5%. Mutants sporulated in the presence of alcohols at a frequency of 30 to 40%. Sporulation in the wild-type cells was sensitive to alcohol at the beginning of sporulation (stage zero). Sensitivity to alcohol in...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولMutants of Bacillus subtilis
Enzyme activities of glycolysis and glyconeogenesis are present in spores of Bacillus subtilis, the rate-limiting step of glucose (GLC) metabolism being its phosphorylation. GLC allows initiation of germination in the presence of fructose (FRU) and asparagine (ASN), not because it is used via the EmbdenMeyerhof path, but because it is oxidized in the nonphosphorylated form via the spore-specifi...
متن کاملLipiarmycin-resistant ribonucleic acid polymerase mutants of Bacillus subtilis.
Lipiarmycin inhibited the activity of deoxyribonucleic acid-dependent ribonucleic acid (RNA) polymerase in vitro. We showed that inhibition was due to interference by lipiarmycin with the activity of sigma-containing molecules of RNA polymerase. Transcription by core enzyme was relatively resistant to the drug, but addition of sigma led to highly drug-sensitive RNA synthesis. We isolated lipiar...
متن کاملProperties of Bacillus subtilis mutants temperature sensitive in germination.
A new mutant of Bacillus subtilis defective in the outgrowth phase of spore germination has been isolated. When incubated at 46 C, the spores of the mutant gave rise to abnormally large swollen cells. Genetic crosses show that the mutant is different from the three previously described. The genetic analysis indicates two regions of the B. subtilis chromosome involved in the control of the spore...
