The spontaneous and the penicillin-stimulated release of water-soluble, glycerol-labeled polymers was compared in Streptococcus sanguis. In contrast to the spontaneous release occurring in exponentially growing or stationary-phase bacteria, penicillin-treated cells released the bulk of these polymers, and they were not replenished by synthesis during antibiotic treatment. Furthermore, a major portion of the extracellular polymers was characterized as acylated lipoteichoic acid.
比较了血链球菌中水溶性、甘油标记聚合物的自发释放和青霉素刺激释放。与指数生长期或稳定期细菌中发生的自发释放不同,经青霉素处理的细胞释放了这些聚合物的大部分,并且在抗生素处理期间它们不会通过合成进行补充。此外,细胞外聚合物的主要部分被鉴定为酰化脂磷壁酸。
