Abstract excerpt
A mutant strain of Mycobacterium aurum was isolated that produced mainly lycopene (>80%) with a total carotenoid content of 1.2 mg g(-1) dry biomass when grown on yeast extract and glucose. Lycopene content of the cells could be significantly increased, up to 7.4 mg g(-1) biomass, by growing the cells at suboptimal initial culture pH (pH 6-6.4) or by using high salt concentration (85 mM NaCl) in the culture...
