ABSTRAKT

The addition of wheat bran to the sawdust medium enhanced the activity levels of endo-glucanase, exo-glucanase, β-glucanase, xylanase and laccase, whereas the addition of cottonseed cake and deoiled soybean resulted in decreased activity of these enzymes of the culinary-medicinal mushroom Flammulina velutipes. Wheat bran and deoiled soybean, at the proportion of 10%, were the best supplements for mycelial growth of F. velutipes. The addition of wheat bran to the medium caused increased biological efficiency and quicker spawn running than in the control medium, whereas poor spawn running and no fruiting-body formation were recorded in the medium enriched with cottonseed cake, soybean meal, or deoiled soybean.
