Heat shock stress in Bacteroides fragilis
ARCHIVES OF MICROBIOLOGY(1985)
摘要
The response to heat shock was investigated in the obligate anaerobe Bacteroides fragilis. The cells responded quickly to stress and synthesised seven heat shock proteins immediately upon exposure to heat. The apparent molecular weights of the seven proteins differed from the apparent molecular weights of the proteins induced by UV irradiation, O2 and H2O2. Heat shock did not induce phage reactivation whereas UV irradiation, O2 and H2O2 did induce phage reactivation systems. Ethanol did not elicit the heat shock response. Two heat resistant B. fragilis mutants were isolated. Both mutants lost the ability to synthesise the same two heat shock proteins. It is concluded that the heat shock response and the responses to UV irradiation, O2 and H2O2 represent two independent groups of stress responses in B. fragilis.
