Average cfu/ml of P. aeruginosa RR1 and P. oleovorans 96 h after inoculation when using hexadecane as the sole carbon source (*18 h for LB media). Hexadecane (C16) was supplemented in the cultures at either 0.46%, 4.6%, or 9.2% (w/v). a Cfu/ml when 2.5 or 5 g/L of NH₄Cl was supplied as the nitrogen source (2.5 Cl and 5 Cl). b Cfu/ml when 1.9 or 3.8 g/L of NH₄NO₃ was supplied as the nitrogen source (1.9 NO3 and 3.8 NO3). Error bars represent standard deviations from the mean values of three replicates
