Abstract
The carbohydrate fraction of a hot spring sulfur-turf bacterial mat was shown to contain cellulose by the examination of neutral sugar composition, methylation analysis, and the identification of free oligosacchrides obtained from an acetolyzate of the desulfurized sulfur-turf mat. This suggested that the sulfur-oxidizing bacteria composing the sulfur-turf were producers of cellulose.
摘要
通过对中性糖组成、甲基化分析以及从脱硫硫草垫的乙酰解产物中获得的游离寡糖的鉴定，表明温泉硫草细菌垫的碳水化合物部分含有纤维素。这表明构成硫草的硫氧化细菌是纤维素的生产者。
