Procedure for large-scale production of astaxanthin from haematococcus
First Claim
1. A process for cultivating Haematococcus cells for the large scale production of astaxanthin-enriched Haematococcus cells comprising:
- (a) cultivating said Haematococcus cells under conditions suitable for optimal vegetative growth of said cells, wherein said conditions comprise growing the cells under a light intensity in the range of about 30-140 μ
mol photons.m-2·
S-1 and at a temperature of between about 15-28°
C.; and
(b) collecting the cells grown according to (a) and cultivating them further under conditions suitable for optimal induction and accumulation of astaxanthin in said cells, wherein said conditions comprise inoculating said cells of (a) into a growth solution consisting essentially of tap water to which is added CO2 as the carbon source for the cells, and growing said cells at a temperature of below 35°
