摘要
用HCI水解玉米粉,再用(NH_4)OH调pH至6.8,将热带假丝酵母接种到该发酵基质中,于摇床中30℃,200r/min培养两天。蛋白质含量由8.4%提高到27.4%;蛋白质中赖氨酸含量由32.1g/kg提高到73.4g/kg,色氨酸含量由6.8g/kg提高到14.8g/kg。
Corn meal was hydrolyzed in HCI ,and pH adjusted to 6.8 with (NH_4)OH. The substrate was inoculated with Cadida trapicalis ,then cultivated in a shaker at 30℃ and in 200r/min for 2 days. The Results indicated that the protein content in corn meal grew from 8.4 to 27.4%the lysine in the protein increased from 32.1 to 73.48/kg,the tryptophan from 6.8 to to 14.8g/kg. This shows that the nutritional value of corn meal can be improved with this method.
