摘要： 利用豆腐生产工艺中的副产物黄泔水为溶剂,通过单因素实验和正交实验,在28℃、200 r/min摇瓶培养条件下,确定高大毛霉MHC-7最佳培养基为黄豆粉3%、可溶性淀粉0.4%、硫酸镁0.2%、磷酸二氢钾0.2%、蔗糖0.3%和黄泔水。培养基中碳氮比为1.5、最适接种量为6%、最适起始pH值为6.0,通过生物量测定,MHC-7液体培养在36 h达到最大值(1.363 g/100 mL)。

Abstract: Using yellow hogwash,the byproduct in the production of fermented tofu,as the solvent,via the single element and orthogonal experiment,the optimum medium of Mucor mucedo (L.) Fres is determined:shaking with 28℃,200 r/min,3% soybean powder,0.4% soluble starch,0.2% magnesium sulfate,0.2% potassium dihydrogen phosphate,0.3% sucrose and yellow hogwash.The adequate C:N ratio in medium is 1.5. The initial optimal inoculum is 6% and pH is 6.0. Through biomass determination,the fermentation in liquid reached the maximum value in the 36 hour(1.363 g/100 mL).

Key words: Mucor mucedo (L.) Fres, liquid fermentation, growth curve
