摘　　要：经土壤分离、纯化、筛选到2株耐高酸、高渗透压、高含水量生长环境、菌体蛋白含量40%以上的菌株,经鉴定为产朊假丝酵母(1号)、黑曲霉(2号)。通过混合发酵果渣结果表明,果渣中果胶、高酸高糖被转化,蛋白质含量大大提高。该菌株适合应用于大生产。The process of screening two highprotein strains for apple waste fermentation is demonstrated.After seperation and purification from the earth, two high acid resistant,high osmotic pressure resistant strains were screened out, which can live in the high water content enviroment.Protein content of the each strain accounts more than 40%.They were identified as Candium utilis and Asperillus niser.It is showed that the pectin and sugar in the apple waste were converted. Protein content was greatly increased. This technology is suitable for industrial manufacture.
