【摘要】 本文采用甘蔗渣酶解液配制培养基,对碳氮源浓度对于异养小球藻细胞生长和脂肪酸积累的影响进行了研究。当蔗渣酶解液中葡萄糖浓度和氮源浓度分别为10 g/L和0.1 mol/L时,小球藻胞内脂肪酸产量和含量均达到最大值,分别为0.88g/L和17.4%。小球藻胞内主要脂肪酸组分为油酸、亚油酸和十六烷酸等。本研究结果表明采用蔗渣酶解液为碳源异养培养小球藻,可以达到较高的脂肪酸产量,以用于生物柴油的生产制备。更多还原

【Abstract】 The effects of glucose and nitrogen concentrations in medium of sugarcane bagasse hydrolysate on cell growth and fatty acids accumulation of heterotrophic Chlorella protothecoides were investigated.The maximal fatty acids yield(0.88g/L) and fatty acids content(17.4%) were obtained in medium of sugarcane bagasse hydrolysate containing 10g/L glucose and 0.1 g/L nitrogen source.The main fatty acid components were composed of oleic acid,linoleic acid,cetane aicd,etc.This indicated that the high yield of fatty acids for biodiesel production was achieved using sugarcane bagasse hydrolysate as organic carbon.更多还原
