为探究餐厨垃圾水解液发酵产油脂的动力学特征和影响因素,以Saccharomyces cerevisiae As2.516（S.cerevisiae As2.516）为供试菌株,在初始餐厨垃圾水解液加入量为90%、搅拌速率为180 r/min、通气量为2.5 L/min、发酵周期为10 d的条件下,进行1 L发酵罐发酵实验。实验结果表明,S.cerevisiae As2.516的最优初始培养条件如下:pH值为6、温度为30℃、生物接种量为10%;在此实验条件下,发酵第7天油脂产量最高达4.6 g/L,此时生物量为13 g/L,油脂产率为36.1%;发酵产生的脂肪酸主要由C16和C18脂肪酸组成。餐厨垃圾水解液中的无机盐钠（Na+）、钾（K+）、铁(Fe3+)、镁(Mg2+)、锰(Mn2+)含量丰富,除需添加微量...

To investigate the kinetic characteristics and influencing factors of oil production from kitchen waste hydrolysate fermentation,a fermentation experiment was carried out in a 1 L fermenter,in which Saccharomyces cerevisiae As2.516 (S.cerevisiae As2.516) was used as a test strain the dosage of initial kitchen waste hydrolysate was 90%,agitation speed was 180 r/min,aeration rate was 2.5 L/min and fermentation cycle was 10 days.The initial optimal culture conditions for S.cerevisiae As2.516 were as follows:pH of 6,temperature of 30 ℃ and inocula...
