Abstract

Two species of gliding bacteria were isolated from a marine biofilm. They were described and identified as members of the genus Cytophaga. One of them (RB1057) produced an extracellular inhibitor of colony expansion of the other (RB1058). The inhibitor was characterized as a glycoprotein with an apparent molecular mass of 60 kDa. It inhibited RB1058 adhesion to and gliding on substrata. Motility and adhesion of several other aquatic gliding bacteria were not measurably affected by this agent.

摘要

从海洋生物膜中分离出两种滑行细菌。它们被描述并鉴定为噬纤维菌属的成员。其中一种(RB1057)产生了另一种(RB1058)菌落扩展的细胞外抑制剂。该抑制剂被表征为一种表观分子量为60 kDa的糖蛋白。它抑制RB1058在基质上的黏附与滑行。其他几种水生滑行细菌的运动性和黏附性并未受到该因子的显著影响。
