摘要 研究了体积溶氧系数(KLa)对被孢霉产花生四烯酸的影响.结果表明在摇瓶水平放大培养中,KLa、被孢霉生长、花生四烯酸(AA)产量均降低.利用0.3%Tween20作为氧载体提高各级的KLa,可以较大幅度提高AA产量. The effect of KLa on Mortierella alpina producing arachidonic acid was studied.The results showed that KLa, Mortierella growth and AA yield decreased during the scaleup culture of Mortierella at the level of flask.0.3%Tween 20,acting as oxygenvector,increased KLa at every level of flask culture and substantially increased AA yield.
