Abstract

By enrichment with xylose, nine mesophilic strains of anaerobic bacteria were obtained from various sources. Two isolates appear to belong to the genus Eubacterium. Six other strains belong to the genus Clostridium. Three of the isolated strains utilized larch wood xylan. The percentage of utilization of xylose and xylan and the yield of fermentation end products--viz. acetic acid and butyric acid--are equivalent to that of Clostridium acetobutylicum (ATCC 824) and reported thermophilic strains.

摘要

通过木糖富集培养，从不同来源获得了9株嗜温厌氧菌。其中两株分离菌似乎属于真杆菌属。另外6株属于梭菌属。分离出的菌株中有3株利用落叶松木聚糖。木糖和木聚糖的利用率以及发酵终产物（即乙酸和丁酸）的产量与丙酮丁醇梭菌（ATCC 8,24）和已报道的嗜热菌株相当。
