Figure 3From: The influence of microbial physiology on biocatalyst activity and efficiency in the terminal hydroxylation of n-octane using Escherichia coli expressing the alkane hydroxylase, CYP153A6Impact of FeCl 3 concentration on CYP153A6 expression in LB {■} and glucose based defined medium {●}. Harvested biomass was re-suspended in 0.2 M Sodium Phosphate buffer containing glucose and used for octane biotransformation. Rate of octanol production was determined using biomass from both LB {□} and chemically defined medium {○} at 23°C.Back to article page
