Abstract
Sublethal injury was noted in Escherichia coli after cells were exposed to solar radiation. Injury was detected by differential plate counts between complete and minimal media that were observed with sunlight-exposed cells but not with cells kept in the dark. Since addition of catalase or pyruvate to minimal medium overcame or repaired this injury, the catalase system appeared to be the site of injury.
摘要
细胞暴露于太阳辐射后，在大肠杆菌中观察到亚致死损伤。通过在完全培养基和基本培养基之间进行差异平板计数来检测损伤，在暴露于阳光的细胞中观察到了这种差异，但在黑暗中保存的细胞中未观察到。由于向基本培养基中添加过氧化氢酶或丙酮酸可克服或修复这种损伤，过氧化氢酶系统似乎是损伤发生的部位。
