Abstract
The purpose of the present study was to investigate the inhibition of Vibrio by Roseobacter in a combined liquid-surface system. Exposure of Vibrio anguillarum to surface-attached roseobacters (10(7) CFU/cm(2)) resulted in significant reduction or complete killing of the pathogen inoculated at 10(2) to 10(4) CFU/ml. The effect was likely associated with the production of tropodithietic acid (TDA), as a TDA-negative mutant did not affect survival or growth of V. anguillarum.
摘要
本研究旨在探究玫瑰杆菌对弧菌的抑制作用在联合液-面系统中的表现。将鳗弧菌暴露于附着于表面的玫瑰杆菌（10(7) CFU/cm(2))中，会导致接种于 10(2) 至 10(4) CFU/ml 的病原体数量显著减少或完全杀灭。这一效果可能与 tropodithietic acid (TDA) 的产生有关，因为 TDA 阴性突变体不会影响鳗弧菌的存活或生长。
