  • 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.

  • Method of producing lycopene through the fermentation of selected strains of blackeslea trispora, formulations and uses of the lycopene thus obtained
    Publication number: 20050106657
    Abstract: The method of fermentation with selected strains of B. trispora described in the present invention makes it possible to achieve lycopene yields higher than those currently described. The methods of isolation, purification and formulation are applicable to any natural source of lycopene, especially to submerged cultures of mucoral fungi of the genera Blakeslea, Choanephora, Phycomyces or Mucor. The method of extraction makes it possible to simplify the recovery process and increase the purity of the product, relative to the methods previously described. The methods of formulation provide high added value, since they make it possible to obtain stabilized preparations of lycopene for direct application in the food and pharmaceutical fields.
