Abstract

Hyphomonas strain MHS-3, a member of a genus of primary colonizers of surfaces immersed in marine water, synthesizes two structures that mediate adhesion to solid substrata, namely, capsular exopolysaccharide and fimbriae. Specific stains, gold-labelled lectins, and monoclonal antibodies, along with transmission electron microscopy of synchronized populations, revealed that both structures are polarly and temporally expressed. The timed synthesis and placement of the fimbriae and capsule correlated with the timing and locus of MHS-3 adhesion.

摘要

海洋水体表面初始定植菌属的一株海单胞菌(Hyphomonas strain MHS-3)能够合成介导黏附于固体基质的两种结构,即荚膜多糖和菌毛。特异性染色、金标记的凝集素和单克隆抗体,以及同步化群体的透射电镜检查揭示,这两种结构均呈极性和时相性表达。菌毛和荚膜的定时合成和定位与 MHS-3 黏附的时间和位置相关。
