玉米浆作为氮源对透明质酸发酵的影响

Effects of Corn Steep Liquor as Nitrogen Source on Hyaluronic Acid Fermentation

采用玉米浆替代牛肉膏和蛋白胨作为氮源,在摇瓶和30 L发酵罐中进行透明质酸发酵,分析测定了直接利用玉米浆作为氮源和玉米浆酶解液作为氮源两种情况下透明质酸的发酵产量。结果表明,透明质酸产量太低,玉米浆不适合作为透明质酸发酵的氮源。

Instead of beef extract and peptone,corn steep liquor was used for hyaluronic acid fermentation as nitrogen source in shake flask and 30L fermentor.The production of hyaluronic acid fermentation was determined when corn steep liquor and corn steep liquor enzymatic hydrolyzate were both used as nitrogen source.The results showed that the production of fermentation is too low,so corn steep liquor is not suitable for hyaluronic acid fermentation as a nitrogen source.
