FIGURE 2.
Growth and chloromethane degradation during bacterial cultivation. Absorbance at 600 nm (A) and consumption of chloromethane (B). Leisingera methylohalidivorans MB2 (•), M. extorquens CM4 (□) Hyphomicrobium sp. MC1 () and abiotic control (×). Error bars indicate the standard deviation of the mean of three biological replicates. Chloride concentration at the end of cultivation were 9.2 ± 0.2 and 9.2 ± 0.3 mol L-1 for strains CM4 and MC1, respectively, but could not be measured in the high-salt medium used for growth of strains MB2.
