摘要
对节杆菌X7产黄嘌呤氧化酶条件进行了研究.结果表明,最佳产酶条件为:葡萄糖15g/L,酵母膏4 g/L,黄嘌呤14 mmol/L,KCl 10 g/L,发酵时间26 h,产酶活力提高至315.84U/g,每L发酵液总酶活为638 U.
The xanthine oxidase producing conditions of Arthrobacter X7 were stduied in this paper. The results of experiment showed that the optimal conditions were glucose 15 g/L,yeast extract 4 g/L,xanthine 14 mmol/ L and KC1 10 g/L. The enzyme activity reached to 315.84 U/g, and one liter fermentation liquid containted 638 U xanthine oxidase.
