Description
Summary:It was demonstrated for the first time that the level of carotenogenesis by the heterothallic Blakeslea trispora strains intensively forming zygospores decreased under conditions of a surface cocultivation during their sexual interaction as compared with the strains grown separately. On the contrary, carotenogenesis was stimulated during a sexual interaction of the strains incapable of forming zygotes. In a submerged culture, the zygote-forming pairs of strains synthesized a considerably larger amount of trisporic acids but a smaller amount of carotenoids than the strains not forming zygospores. The discovered inverse dependence between zygote formation and carotenogenesis allowed us to suggest the inability to form zygotes as a criterion for selecting carotenogenic strain pairs.
