| 摘 要： | 介绍了葡糖淀粉酶(GA),论述了GA的产酶菌、产酶影响因素、酶的相对分子质量及其结构,酶的一般性质.淀粉加工工业主要应用Aspergillus 和Rhizopus2类菌株来生产用于淀粉糖化的GA;在用半固体培养基在批式发酵状况下能得到最大产量;蛋白水解酶的不良影响可通过细胞固定化、营养及pH控制、生物反应器的设计和使用蛋白酶抑制剂来克服.

| Abstract: | Glucoamylases (GA) is introduced, production of fungi, affecting factors for fungi production, relative molecular weight, structure, and general properties of glucoamylases are reviewed. In starch processing industry, Aspergillus and Rhizopus are mainly used to produce diastased GA; the highest output can be obtained with semisolid culture medium in batch fermentation; bad effects of proteolytic enzyme can be overcome by cell fixation, nutrition, pH control, design of bio-reactor and use of proteinase inhibitor. |
