Protein enrichment of sweet potato residue with amylolytic moulds by solid-state fermentation was higher than that obtained with amylolytic yeasts. The optimum initial moisture content for protein enrichment was 66% to 75%. Incrementally added nitrogen sources to the culture at zero time and at 24 h considerably improved the final protein content. During the cultivation, the moisture, ash and ATP contents increased, while the pH value decreased. A 1:1 co-culture of amylolytic mycelial fungi yielded a product with 32.4% crude protein after 4 days incubation at 30 degrees C.
通过固态发酵利用淀粉酶霉菌对甘薯残渣进行蛋白质富集,其效果高于使用淀粉酶酵母的情况。蛋白质富集的最佳初始水分含量为66%至75%。在培养开始时和24小时时逐步添加氮源,显著提高了最终的蛋白质含量。在培养过程中,水分、灰分和三磷酸腺苷(ATP)含量增加,而pH值下降。在30℃下培养4天后,淀粉酶丝状真菌的1:1共培养物产生了粗蛋白含量为32.4%的产品。
