Abstract
- The release of LTA from chemostat-grown cultures of S. mutans and L. fermentum is dependent on the generation time and pH. 2) The growth rate affects the immunogenicity of LTA and the wall polysaccharide of L. fermentum. 3) The growth of L. plantarum under glucose limitation influences the glucose content of the wall teichoic acid. The composition of the wall polysaccharide of S. mutans Ingbritt may also be changed under these conditions. 4) The conditions of autoclaving used to release cell wall antigens can hydrolyse the covalent linkage between polysaccharide and peptidoglycan.
摘要
- 变形链球菌和发酵乳杆菌在恒化器培养条件下LTA的释放取决于代时和pH值。2) 生长速率影响发酵乳杆菌LTA和壁多糖的免疫原性。3) 植物乳杆菌在葡萄糖受限条件下的生长会影响壁磷壁酸的葡萄糖含量。在这些条件下，变形链球菌Ingbritt壁多糖的组成也可能发生变化。4) 用于释放细胞壁抗原的高压灭菌条件可水解多糖与肽聚糖之间的共价连接。
