醋酸對十一種 -變形菌綱的抑菌及殺菌作用探討

Abstract

很多重要的致病菌都屬於- 變形菌綱， 本研究探討低濃度醋酸對- 變形菌綱(gammaproteobacteria) 中的海水性細菌之生長抑制及殺菌作用， 針對Morganella morganii, Pseudomonas sp., Pseudoalteromonas sp.,及Vibrio spp.,等細菌，在含有0.125%、0.0625%及0.03125%的醋酸下出現不同的影響作用，結果顯示，分離出的11 株 -變形菌綱細菌中，Morganella morganii具有較高的醋酸耐受性，研究中最高醋酸濃度為0.125%，在此條件下僅出現些微的抑制作用，其餘10 株菌在0.125%下皆無法生長。

An exceeding number of important pathogens belong to gammaproteobacteria. The aim of this study is to verify that marine gammaproteobacteria, namely, Morganella morganii, Pseudomonas sp., Pseudoalteromonas sp., and Vibrio spp., are affected by acetic acid. Three different concentrations of acetic acid, 0.125%, 0.0625% and 0.03125% in LB broth cultured bacteria were used. Ten isolates were inhibited by 0.125% of acetic acid in LB broth, but Morganella morganii was not.
