Zusammenfassung:The invention relates to a method for the fermentation production of natural beta-carotene by adding multiple fermentation accelerants. The method comprises the working procedures of slant culture, seed culture and fermentation culture, wherein during fermentation culture, the fermentation culture production of the natural beta-carotene is promoted by adding the fermentation accelerants. Compared with the prior art, the method has the advantages that the multiple fermentation accelerants obtained by test comparison are added to a fermentation medium, comprise a surface active agent, alkane, part of metabolites in tricarboxylic acid cycle, metal ions and oxygen stress effect matters, are expected to stimulate breath and growth by changing the permeability of cell membranes and increase the solubility of oxygen so as to meet the aerobic fermentation requirements of blakeslea trispora.
