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.
This paper reported that the authors isolated large numbers of myxobacteria from more than 100 samples collected in many places of China.More than 400 pure strains were obtained.These strains belonged to 10 genera of Myxococcales.The most frequent genera isolated were Myxococcus,Sorangium,Corallococcus, and Cystobacter.Melittangium was seldom isolated.No Chondromyces and Haploangium were found.
