absorbent clear and colorless infrared radiation composition

process for obtaining pgmentos released into the medium, cultivation of microalgae of the class eustgmatophyceae the present invention relates to a process for obtaining pigments released into the medium, cuilivos mieroalgas of the Ts / igniatophycecic class. 5de the process according to the present invention primarily induce, through manipulation of the cultivation conditions, increased production of pigments carotcnoides between them. in a second stage of the process, by simple centrifugation techniques there is a dc separation cm biomass rich polysaccharides, viable cells, and the byproduct, carolenoides containing pigment, which may have various applications.
