适于生产生物柴油的产油酵母菌的筛选

摘要

Ten oil-producing strains were isolated from soil samples. After shake-flask screening, two strains (named JM-B and JM-D) were obtained. The physiological and biochemical characteristics of the both strains were determined. The gas chromatograph analysis showed that the fatty acids composition of strain JM-D was similar to vegetable oil. This indicated that strain JM-D can be used to produce biodiesel.%该文从土壤中筛选出10株产油脂的酵母菌,经摇床培养复筛确定其中2株优良产油酵母菌JM-B、JM-D.通过对2株菌生理生化特性的试验,进一步对其发酵性能进行研究并对酵母菌株油脂脂肪酸组成进行测定.菌株JM-D油脂脂肪酸组成与植物油相似,适合用于发酵生产生物柴油,是今后发酵生产生物柴油的优良菌株.
