Fig. 5From: Enhancement of the catalytic activity of Isopentenyl diphosphate isomerase (IDI) from Saccharomyces cerevisiae through random and site-directed mutagenesisCell growth rates, lycopene productions and lycopene yields, substrate consumption rates during aerobic fed-batch fermentation. a The cell growth rates of CHL-1 and CHL-2 were similar, and lycopene production of CHL-2 were approximately 2.8-fold of CHL-1. b The substrate rates of CHL-1 and CHL-2 were similar, while final lycopene yield of CHL-2 was approximately 3.1-fold of CHL-1Back to article page
