Fig. 4From: Deregulation of phytoene-β-carotene synthase results in derepression of astaxanthin synthesis at high glucose concentration in Phaffia rhodozyma astaxanthin-overproducing strain MK19Relative expression of creA, alcA, and carotenoid synthesis genes in JCM9042 (a) and MK19 (b) at glucose induction times 0 and 30 min. Expression at 48 h was defined as 1. alcA, encoding the alcohol dehydrogenase I and repressed by creA, was used as controlBack to article page
