Process for the preparation of carotenoids by submerged fermentation with mixed cultures of (+) and (-) strains of the fungus Blakeslea trispora

摘要

The invention relates to a simple and effective method for the production of β-carotene or lycopene by submerged fermentation with mixed cultures of (+) and (-) - strains of the fungus Blakeslea trispora, which is characterized by a high productivity of B. trispora strains. The high productivity is achieved by the method according to the invention, which takes into account the morphological state of the filamentous half-growths and the growth state in the mixing of the strains (the so-called mating).
