Abstract

We examined the effect of growth conditions in chemostat culture on the quantity and composition of the cell wall teichoic acids of Streptococcus mutans BHT and Lactobacillus plantarum NCIB 7220 and the membrane lipoteichoic acid from S. mutans Ingbritt. With the cell wall teichoic acids, which are covalently linked to peptidoglycan, the amount of teichoic acid is independent of the growth conditions employed. However, the extent of glucosyl substitution of the polymer from L. plantarum was dependent on growth conditions. S. mutans Ingbritt lipoteichoic acid, on the other hand, was little affected by growth conditions in terms of composition or serological activity, but the amount produced was markedly affected by changes in growth conditions.

摘要

我们研究了恒化器培养中的生长条件对变形链球菌BHT和植物乳杆菌NCIB 7220细胞壁磷壁酸的数量和组成以及变形链球菌Ingbritt膜脂磷壁酸的影响。对于与肽聚糖共价连接的细胞壁磷壁酸,磷壁酸的量与所采用的生长条件无关。然而,植物乳杆菌聚合物的葡萄糖基取代程度取决于生长条件。另一方面,变形链球菌Ingbritt脂磷壁酸在组成或血清学活性方面受生长条件的影响较小,但产生的量受到生长条件变化的显著影响。
