菌物研究

以3个不同裂褶菌菌株（L1,L2,L3）为研究对象，测定其菌丝生长初期、半袋期、满袋期和子实体生长期间8种胞外酶活性，探究在含有葡萄枝条的栽培基质上不同菌株不同时期的胞外酶活性与产量的关系。结果表明：裂褶菌满袋期间的胞外酶活性对其产量至关重要，而在子实体生长过程中胞外酶活性较低；不同菌株间一些胞外酶活性存在共性，而一些胞外酶活性存在差异，其产量也存在差异；半纤维素酶和木聚糖酶是裂褶菌生长过程中重要的胞外酶。

In this study, three different Schizophyllum commune Fr. strains(L1, L2, L3) were selected for the analysis of biological activity in eight kinds of extracellular enzymes during various growth periods of early mycelium, half-bagging or full-bagging and fruiting body as well. Exploration of the relationship between enzyme activities and yields cultivated on the medium containing substrates of grape branches revealed that the extracellular enzyme activities were very much crucial to the production ability of S. commune during the full-bagging period. During the growth period of fruiting body, however, the activities of extracellular enzymes were detected at a very low level. Some of the extracellular enzyme activities were found commonly between the different strains, while some differed from each other which also showed a difference in their yields. Basing on the results obtained at the present study, hemicellulase and xylanase were considered as the mostly important extracellular enzymes during the growth of S. commune.
