摘　　要：本文介绍了柠檬酸废渣生物转化为饲料蛋白的研究成果，通过四株酵母菌和二林霉菌分别在柠檬酸废渣上进行单菌和组合菌试验，获得适合于该废渣上进行固体发酵的一组合菌株，进而探讨该组合菌株的发酵条件。试验结果表明：在２８℃，基质中的初始含水量在５５％～６５％范围内进行固体连续发酵，产品的粗蛋白可增加到４５％，纤维素含量从１２．４０％下降到８．５３％，提高了废渣的利用价值。This article introduces a result of the scientific research about biological transformation of fermentation solid of citric acid into protein feed. The fermentation tests of single strain and combination strain are carried out under optimum culture conditions. The results indicate that final product contains 45% of crude protein, the content of crude fiber in the product is decreased from 12.40% to 8.53% , when culture temperature is 28℃ and inital moisture content is 55%～65%
