Abstract
Treatment of Streptococcus mutans GS-5 cells with concentrations of penicillin G within a relatively narrow range resulted in substantial lysis. This penicillin-induced lysis was dependent upon cell density and pH of the lysis medium. Other oral streptococci (Streptococcus sobrinus, Streptococcus rattus, and Streptococcus cricetus) also demonstrated substantial levels of penicillin-induced lysis under appropriate conditions. Lesser degrees of lysis were seen in a related organism, Streptococcus ferus.
摘要
用相对较窄浓度范围内的青霉素G处理变形链球菌GS-5细胞会导致大量细胞裂解。这种青霉素诱导的裂解取决于细胞密度和裂解培养基的pH值。在适当条件下，其他口腔链球菌（远缘链球菌、鼠链球菌和仓鼠链球菌）也表现出大量的青霉素诱导裂解。在相关菌株野生链球菌中观察到的裂解程度较低。
