Fig. 5From: Deregulation of phytoene-β-carotene synthase results in derepression of astaxanthin synthesis at high glucose concentration in Phaffia rhodozyma astaxanthin-overproducing strain MK19(a) Relative expression of alcA and carotenoid synthesis genes in MK19 and MK19-CreA9 (mutant 9) at 24 h at 40 g/L glucose. Expression in MK19 was defined as 1. (b) Astaxanthin content of MK19 and mutant 9 as a function of fermentation timeBack to article page
