Effects of enhancing the carbamoyl phosphate supply on l-arginine production from glucose and l-ornithine. a Plasmids p-AGR-1 and p-AGR-2 were constructed for l-arginine overproduction. b l-arginine production and acetate formation of strains N8-N10. c Cell growth and l-arginine yield from l-ornithine of strains N8-N10. N8: BW25113 ΔargA ΔspeF ΔspeB ΔastA ΔargR, overexpression of argIGH; N9: BW25113 ΔargA ΔspeF ΔspeB ΔastA ΔargR, overexpression of argIGH, carAB; and N10: BW25113 ΔargA ΔspeF ΔspeB ΔastA ΔargR, with empty plasmid pZE. Error bars are the standard deviation for three independent experiments
