【中文摘要】 研究了金針菇液體菌種培養(yǎng)過程中菌絲球數(shù)量、pH、還原糖和氨基氮含量及酶活性等指標(biāo)的變化情況。結(jié)果表明 ,菌絲球數(shù)量和活性與上述指標(biāo)具有一定的相關(guān)性。當(dāng)培養(yǎng)液中還原糖含量和氨基氮含量分別為 3.4 0 g 10 0mL和 11.10mg 10 0mL ,纖維素酶活性、漆酶活性和蛋白酶活性分別為 1.10U、0 .0 17U和 0 .17U ,pH為 6.3時 ,菌絲球數(shù)量與活性最高

【英文摘要】 During the culture process of Flammulina velutipes liquid strains, the variation of mycelial pellet numbers, pH, the contents of reducing sugar and amino nitrogen and the enzyme activity was studied. The results showed that the numbers and activity of mycelial pellets were related to those indexes, and that the quality of the liquid strain was the best when the contents of reducing sugar and amino nitrogen were 3.40g/100mL and 11.10mg/100mL resp. and the activities of cellulase, laccase and proteinase were 1.10U,0.017U and 0.17U resp..
