Abstract

Streptococcus cricetus AHT exhibited a requirement for manganese for growth and expression of the glucan-binding lectin. While low concentrations of manganese (0.1 to 10 microM) were able to support growth, higher concentrations (greater than 100 microM) were required for full expression of the glucan-binding lectin. The manganous-aquo ion may be important in cellular adhesion and accumulation processes in dental plaque.

摘要

仓鼠链球菌AHT生长以及表达葡聚糖结合凝集素需要锰。虽然低浓度的锰(0.1至10微摩尔)能够支持生长,但葡聚糖结合凝集素的完全表达需要更高浓度(大于100微摩尔)的锰。二价锰水合离子在牙菌斑的细胞黏附和聚集过程中可能很重要。
