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 KLa on Mortierella alpina producing arachidonic acid was studied.The results showed that KLa, Mortierella growth and AA yield decreased during the scaleup culture of Mortierella at the level of flask.0.3%Tween 20,acting as oxygenvector,increased KLa at every level of flask culture and substantially increased AA yield.
