Fig. 1From: l-amino acids affect the hydrogenase activity and growth of Ralstonia eutropha H16Effects of LB medium components on R. eutropha H16 bacterial growth parameters. Bacteria were grown aerobically, pH 7.0, for 72 h: Kinetic of A OD (600 nm) (optical density), B pH, and C) ORP, (n = 5, p < 0.05). The ORP was measured by using Pt and Ti-Si electrodes and was expressed in mV [vs Ag/AgCl (saturated by KCl)]. Control is FN (Fructose-Nitrogen medium), 0.5% of LB (Luria–Bertani Medium), and YE- (Yeast extract) and tryptone were supplemented into FN. The average data of 3 independent measurements are presented with standard errorsBack to article page
