Abstract

Exponentially growing tetracycline-treated Escherichia coli cells release (an) as yet unidentified compound(s) into the medium. These compounds produce a protective effect on E. coli cells under conditions of heat, oxidative, and osmotic shocks, or in the presence of tetracycline. The protective effect is manifested as an acceleration of growth in the presence of tetracycline or under conditions of heat shock or as a shortening of the period of adaptation to other stresses.

摘要

经四环素处理后呈指数生长的大肠杆菌细胞会向培养基中释放一种(或几种)尚未鉴定出的化合物。在热激、氧化应激和渗透压冲击条件下,或者在四环素存在的情况下,这些化合物对大肠杆菌细胞产生保护作用。这种保护作用表现为在四环素存在或热激条件下生长加速,或者表现为缩短对其他应激的适应期。
