Effects 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 errors
