摘要:
本文首次对假大白菇深层发酵过程中的5项生理指标与6种胞外酶的活性进行了测定,结果表明,菌丝生物量在第10 d达到最大值;pH值先降后升;胞外还原糖与蛋白质浓度分别于第5 d、第6 d达到峰值;胞外多糖含量在第6 d出现峰值;淀粉酶、CMC酶、纤维素脱脂棉酶与滤纸酶的酶活变化趋势相近;愈创木酚氧化酶与邻苯二酚氧化酶的酶活性很小。
Abstract:
Dynamic variations of 5 physiological indices and octivities of 6 kinds of extracellular enzymes during the submerged culture of Russula pseudodelica Lange. were investigated. The results showed that the maximum of hypha growth was 6.58 g·L-1,appeared in the 10th day; pH of fluid medium decreased, then increased; the peak times of extracellular protein and deoxioized saccharide were in the 5th day, the 6th day; extracellular polysaccharide appeared its maximum in the 6th day ; dynamic variation of diastase, CMC enzyme, ellulose during the submerged culture were quite similar; the activities of guaiacol oxidase and polyphenol oxidase were very low during the submerged culture.
