  • Method of production of ?-carotene by fermentation in mixed culture using (+) and (?) strains of
    Patent number: 7252965
    Abstract: The invention consists of fermenting selected strains of Blakeslea trispora in conditions such that ?-carotene is produced in the form of stabilized preparations with residual contents of other carotenoids (?-carotene and ?-zeacarotene). The fermentation conditions chosen include the programmed addition of oxygen and/or ?-ionone during fermentation, and control of the age of the vegetative growth phases of the strains employed. The ?-carotene obtained can be used in the pharmaceutical and food sectors.

  • Method of production of astaxanthin by fermenting selected strains of xanthophyllomyces dendrorhous
    Publication number: 20050124032
    Abstract: The present invention describes methods for (i) obtaining astaxanthin-overproducing strains of X. dendrorhous and (ii) the use of the aforementioned strains in improved conditions of fermentation. The methods used for selecting the strains are based on: (i) resistance to inhibitors of steroid synthesis, to inhibitors of respiration and to compounds that induce the formation of free radicals, (ii) color intensity of the colony and production of carotenoids on solid medium, (iii) production of astaxanthin in darkness, (iv) production of astaxanthin in conditions with a raised temperature and (v) production of astaxanthin with carbon sources other than glucose. These methods permit the efficient selection of mutants of X. dendrorhous with astaxanthin yields higher than the parent strain and little accumulation of other carotenoids. Cultivation of X. dendrorhous in liquid medium makes it possible to obtain a biomass that can be used directly in human and animal nutrition.
