Butanol and isobutanol accumulation from glycine. Yeast cells were grown in Verduyn medium with ammonium sulphate (5 g/L, left panel) or glycine (15 g/L, right panel) as nitrogen source. Biomass accumulation (square), glycine consumption (triangle), butanol (circle) and isobutanol (diamond) productions are shown. The data presented here are representative of three independent experiments.
