A strain of streptomyces S-81-24 was isolated from soil samples collected from Fuzhou, Fujian,China. It was found to produce a chymotrypsin inhibitor. Its spore chains are spiral. The surface of spore is smooth. The aerial mycelium is grey. The substrate mycelium is rose grape violet and no soluble pigment.On the basis of its cul-

链霉菌S-81-24菌株系从福建师范大学校园土壤中分离得到,能产生糜蛋白霉抑制剂。孢子链呈螺旋形,孢子表面光滑,气生菌丝体呈银鼠灰,有黑色吸水湿斑;基内菌丝体呈玫瑰葡萄紫,无可溶性色素。在培养特征和生理生化特性上与已知的吸水链霉菌MC521-C8等相比有一定差别,命名为吸水链霉菌玫瑰紫变种(S.hygroscopicus var.roseoviolaceus var.n.Liu,1981.)

The higher yielding strain was obtained through the reverse mutant of a zero producer of Streptomyces erythreus UV 80 by NTG treatment.To start with NTG treatment(1000μg/ml,lhr)zero mutants were prodruced and followed by NTG treatment again,a revertant showing a 8% higher activity was obtained.The revertant treated further by NTG(1000μg/ml,lhr),the resulted mutant yielded 25% more erthromycin than the original strain.The optimal dose of NTG mutagen was that of producing 90—94% death-rate.At the same time the...
