【摘要】 采用黑曲霉菌株An08-752,经曲盘、发酵床(帘子床)、厚层通风制曲池进行固态发酵,产业化生产饲用β-葡萄糖酶,结果表明:通风曲池厚层通风发酵培养30～32 h,产β-葡聚糖酶最高,发酵酶活力达到1.15×105μ/g;发酵床发酵培养时间35～37 h,产β-葡聚糖酶最高,发酵酶活力达到1.28×105μ/g;曲盘发酵培养32～34 h,产β-葡聚糖酶最高,发酵酶活力达到1.36×105μ/g.更多还原

【Abstract】 The industrial production of β-glucanase was studied in the solid-state fermentation,by Aspergillus niger An08-752 strain with three kinds of equipments.The result showed:the β-glucanase activity reached 1.15× 105 μ/g dry koji at 30～32 h by thick layer ventilation koji tank in the solid-state fermentation;the β-glucanase activity reached 1.28×105 μ/g dry koji at 35～37 h by fermentation tank in the solid-state fermentation;the βglucanase activity reached 1.36×105 μ/g dry koji at 32～34 h by koji tray in the solid-state fermentation.更多还原
