The l-lysine production (filled triangle), cell growth (filled square) and glucose (filled diamond) (a), by-products accumulation (b), and intracellular level of nucleotide-cofactor (c) in strain RGI during cultivating in 5-L fermentors. The total glucose consumption of strain RGI was 264 g L−1. The data represent mean values and standard deviations obtained from three independent cultivations
