考点一、微生物的分离与培养例1植物秸秆中的纤维素可被某些微生物分解。回答下列问题:(1)分解秸秆中纤维素的微生物能分泌纤维素酶,该酶是由3种组分组成的复合酶,其中葡萄糖苷酶可将分解成。(2)在含纤维素的培养基中加入刚果红(CR)时,CR可与纤维素形成色复合物。用含有CR的该种培养基培养纤维素分解菌时,培养基上会出现以该菌的菌落为中心的。 Test sites I. Isolation and culture of microorganisms Example 1 The cellulose in plant straws can be decomposed by certain microorganisms. Answer the following questions: (1) Microbes that decompose cellulose in straw can secrete cellulase, a complex enzyme consisting of three components, in which glucosidase can be broken down. (2) When Congo red (CR) is added to cellulose-containing medium, CR can form a color complex with cellulose. When cellulolytic bacteria are cultured in a medium containing CR, colonies of the bacteria will appear on the medium.
