AbstractThe induction of astaxanthin formation by reactive oxygen species in mixotrophic culture of Chlorococcum sp. was investigated. H2O2 (0.1 mM) enhanced the total astaxanthin formation from 5.8 to 6.5 mg g-1 cell dry wt. Fe2+ (0.5 mM) added to the medium with H2O2 (0.1 mM) further promoted astaxanthin formation to 7.1 mg g-1 cell dry wt. Similarly, Fe2+ (0.5 mM) together with methyl viologen (0.01 mM) promoted astaxanthin formation to 6.3 mg g-1 cell dry wt. In contrast, an addition of KI (1 mM), a specific scavenger for hydroxyl radicals (OH•), together with H2O2 (0.1 mM) and Fe2+ (0.5 mM), to the medium decreased astaxanthin formation to 1.8 mg g-1 cell dry wt. KI (1 mM) also inhibited the enhancement of carotenogenesis by superoxide anion radicals (O2 -), with a decrease of astaxanthin formation to 1.7 mg g-1 cell dry wt. This suggested that O2 - might be transformed to OH• before promoting carotenogenesis in Chlorococcum sp.
