The invention relates to a streptomyces aureus fermentation tetracycline production method. The streptomyces aureus fermentation tetracycline production method comprises the technical processes of dissolving and diluting original streptomyces aureus strains, inoculating and uniformly shaking the dissolved original streptomyces aureus strains into a spore culture medium for cultivation at 33-35 DEGC for 17-25 hours, and sequentially performing seed cultivation and fermented cultivation, wherein the spore culture medium is composed of 1.0-1.5% of bran, 0.003-0.006% of dipotassium phosphate, 1.0-1.6% of starch, 0.01-0.03% of magnesium sulfate, 0.3-0.8% of corn pulp, 0.03-0.06% of yeast powder and 0.01-0.03% of calcium carbonate. Compared with a slant culture manner in the prior art, the streptomyces aureus fermentation tetracycline production method performs fermented tetracycline production through a spore cultivation medium, and by culturing spores through the culture medium, overcomesthe influence factors of agar in a slant culture medium, thereby having the advantages of being free from influence of raw materials, easy in material acquisition and stable in quality; shake-flake seeds are inoculated into the strains cultured through spore solution to ensure robust and well-spread mycelium, and the cultured strains are high in adaptability to culture solutions of every grade, high in metabolism velocity when moved into a fermentation tank, early in tetracycline secretion, short in fermentation cycle and capable of greatly increasing the fermentation level.
