摘　　要：试验利用太空诱变获得的优良菌种黑曲霉ZM-8和酿酒酵母、热带假丝酵母以及白地霉复配制成复合菌剂固体发酵苹果渣。通过正交试验获得了最适的培养基配方和复合菌剂的最佳配方。试验确定的最适培养基配方为硫铵7g、白糖4g、尿素2g、食盐4g,产物中粗蛋白的含量达26.4%,提高了312.50%。复合菌剂的最佳配方为黑曲霉突变株ZM-80.5g、酿酒酵母1.5g、白地霉1.0g、热带假丝酵母1.5g,产物中粗蛋白的含量达27.9%,提高了335.94%。The apple pomace fermented using mutagenic strains-Aspergillus niger ZM-8, Sac.cerevisiae, Candida tropicalis and Geotrichum candidum. There was optimal formula of medium and composite bacterium optimal formula through orthogonal experiment. The experiment optimal formula of medium was as follows： ammonium sulphate 7 g, sugar 4 g, urea 2 g, salt 4 g, the crude protein content of the product 26.4%, increased 312.50%. composite bacterium optimal formula was as follows： Aspergillus niger ZM-8 0.5 g, Sac. cerevisiae 1.5 g, Geotrichum candidum 1.0 g, Candida tropicalis 1.5 g, the crude protein content of the product reached 27.9%, increased 335.94%.
