Abstract

Tetracycline is produced by cultivating a strain of Streptomyces aureofaciens which produces tetracycline to the substantial exclusion of chlortetracycline under submerged aerobic conditions in an aqueous nutrient medium containing assimilable sources of carbohydrate, nitrogen and inorganic salts until substantial quantities of tetracycline are produced, the tetracycline-producing strain being also characterized by its ability to impart to the whole harvest mash a colour characterized by a reflectance curve, when plotted linearly, wherein the vertical distance between the reflectance curve and a straight line drawn through the reflectance curve intercepts at 400 mm and 550 mm is greater at 420 mm than at 430 mm . Specification 690,381 is referred to.
