Abstract
A method for producing the high-value ketocarotenoid astaxanthin by the green microalgain dark-heterotrophic cultures shows excellent growth and high-yield astaxanthin production on glucose-supplemented media in the dark. The specific growth rate and astaxanthin yield can be as high as 0.031 h, and 10.3 mg l, respectively, which are the highest so far reported in heterotrophic algal cultures. The light-independent astaxanthin-producing ability ofcan be employed for commercial production of astaxanthin using industrial fermenters.
