摘要
以液态烷烃为油相对双液相发酵系统进行了研究,通过对体积溶氧系数K_La及油相与水相理化性质的测定,对油相的加入提高发酵能力作了初步解释,并通过青霉素发酵,初步确定了油相体积分数为0.02L/L时可提高青霉素生产能力。
In this paper, a liquid paraffin as oil-phase is introduced into the system which is called twoliquid phase fermentation system.The yield of penicillin is enhanced by 0. 2 to 0.5 times at two percent oil fraction.The theoretical explantion for this fact is given based upon the experimental data measure for volumtric oxygen transfer coefficients (K_La) and on physical and chemical properties of both oil and aqueous phases.
