为了观察严格反应是否参与生物膜形成，在丝氨酸限制下，将大肠杆菌DS 291（MG 1655）及其等基因relA spoT衍生物在恒化器中以0.025和0.25 h（-1）的稀释率生长48 h。严格的反应基因relA和spoT的情况下几乎没有影响的反渗透细胞浓度。一个重要的（P
In order to see whether the stringent response was involved in biofilm formation, Escherichia coli DS291 (MG1655), and its isogenic relA spoT derivative were grown for 48 h in a chemostat at dilution rates of 0.025 and 0.25 h(-1) under serine limitation. The absence of the stringent response genes relA and spoT had little effect on the planktonic cell concentrations. However, a significant (P
