摘要
通过对假单胞菌(Pseudomonassp.)JW12发酵液脂肪酶稳定性的研究,表明了发酵液脂肪的稳定性主要受蛋白酶的影响。当用吐温80作为碳源时,通过对发酵培养基组成的调整,达到降低蛋白酶的目的,提高发酵液脂肪酶酶活。
Stability of lipase produced by Pseudomonas sp.JW12 was investigated.It was found that the stability was mainly influenced by the presence of proteases.When Tween 80 was used as carbon source,the proteases activity declined and lipase activity improved by adjusting fermentation medium composition.
