Mutants and intersexual heterokaryons of Blakeslea trispora for production of beta-carotene and lycopene

Article Abstract:

Improved strains of Blakeslea trispora, obtained by mutation and heterokayosis yield higher content of beta-carotene and lycopene. Incubation of cells with the nicotine shifts the production from beta-carotene into lycopene. Data indicate that the highest production of beta-carotene and lycopene, 39 and 15 milligram per dry mass respectively, is seen in intersexual heterokaryons.

Modification of sexual development and carotene production by acetate and other small carboxylic acids in Blakeslea trispora and Phycomyces blakesleeanus

Article Abstract:

The novel effects of acetate and other small carboxylic acids on the sexual process of two zygomycete fungi, Blakeslea trispora and Phycomyces blakesleeanus are explained. An examination of whether the morphogenetic and metabolic changes induced by sexual interaction were tightly coupled as a single response revealed significance for understanding sexuality in zygomycetes.

Mutants and intersexual heterokaryons of Blakeslea trispora for production of beta-carotene and lycopene

Article Abstract:

Improved strains of Blakeslea trspora by mutation and heterokaryosis yield higher content of beta-carotene than the wild-type and the production shifts to lycopene when the cells are incubated with nicotine. Data indicate that intersexual heterokayons yield the highest production, up to 39 milligram of carotene and 15 milligram of lycopene per gram dry mass.
