Abstract

The reliability of xylan fermentation in distinguishing Bacteroides ovatus from Bacteroides thetaiotaomicron was examined with strains previously identified by DNA homology studies or bacteriophage sensitivity testing or both. All of the 12 B. ovatus strains produced acid ranging from pH 5.0 to 5.6 in peptone-yeast-xylan broth; none of the 19 B. thetaiotaomicron strains produced acid, and the final pH was 6.0 or 6.1. Xylan fermentation and bacteriophage sensitivity-DNA homology appear to be equivalent in their ability to differentiate these two Bacteroides species.

摘要

用先前通过DNA同源性研究或噬菌体敏感性测试或两者鉴定的菌株,检测木聚糖发酵在区分卵形拟杆菌和多形拟杆菌方面的可靠性。12株卵形拟杆菌在蛋白胨-酵母-木聚糖肉汤中均产生了pH值在5.0至5.6之间的酸;19株多形拟杆菌均未产生酸,最终pH值为6.0或6.1。木聚糖发酵以及噬菌体敏感性- DNA同源性在区分这两种拟杆菌属物种的能力上似乎是等效的。
