摘　　要：From mildewed cottonseed cake and stock cultUres of mold and yeast We select more than ten strains of yeastS and molds which can degrade cotton Phenol. At last we got four strains which can degrade cotton phenol highly effeted after mutagenized by physical and chemical factors and induced by cotton Phenol. They belong to Candida tropicalis, Torulopsis candida, Aspergillus flavus and ASPergillus niger. By small and medium size fermenfations, the content of dissociated cottom Phenol all reach safe criterion (the lowest dissociated cotton phenol content is 220mg/ in the defoxicated cottonseed cake), compared with FeSO4 method, defoxicated cottonseed cake looks and taStes well and the content of protein and amino acid are highly enhanced as will.From mildewed cottonseed cake and stock cultUres of mold and yeast We select more than ten strains of yeastS and molds which can degrade cotton Phenol.
