Abstract

Bacteria associated with plants were examined for their ability to use cyclodextrins (CDs) as a unique carbon source. Among 24 strains from eight genera, Xanthomonas were the most active. The cyclodextrin decomposing ability of strains were not related to their taxonomic position. Chemical structure significantly influenced the degradability of cyclodextrins by bacteria. The less rigid ring structure of gamma-CD favoured utilization, whereas methylation led to reduced utilization.

与植物有关的细菌对某些环糊精衍生物的微生物分解
研究了与植物相关的细菌利用环糊精(CDs)作为独特碳源的能力。在8属24株病原菌中,黄单胞菌活性最高。菌株的环糊精分解能力与其分类位置无关。化学结构对环糊精的可降解性有显著影响。γ - cd较弱的刚性环结构有利于利用,而甲基化导致利用减少。
