The present invention is directed toward a method for producing beta-carotene using negative (minus mating type) Mucorales fungal microorganisms. The method includes mutating and selecting negative Mucorales fungal microorganisms, culturing the selected negative microorganisms in an effective medium to produce beta-carotene, and recovering beta-carotene therefrom. The present invention provides negative microorganisms that overproduce beta-carotene, beta-carotene formulations produced by the disclosed method, and the use of such formulations to enhance pigmentation, to reduce damage caused by reactive oxygen species or phototoxic molecules, to prevent or treat cancer or cardiovascular disease, to provide a Vitamin A supplement, to enhance lactation, and to increase fertility.
A beta-carotene-containing biomass produced by a method comprising:
A negative Blakeslea microorganism having all of the identifying characteristics of Blakeslea trispora PF17-13 (ATCC No. 74147).
A biologically pure culture of Blakeslea trispora PF17-13 (ATCC No. 74147), or a mutant thereof, which is capable of producing at least about 0.5 grams of beta-carotene per liter in about 7 days when cultured in an effective production fermentation medium.
A negative Blakeslea microorganism having all of the identifying characteristics of Blakeslea trispora PF17-12 (ATCC No. 74146).
A biologically pure culture of Blakeslea trispora PF17-12 (ATCC No. 74146), or a mutant thereof, which is capable of producing at least about 0.5 grams of beta-carotene per liter in about 7 days when cultured in an effective production fermentation medium.
