FIG. 2.

Consumption of MeBr by washed suspensions of cells incubated with or without chloramphenicol that were grown on acetate (A) (cell density = 8.4 × 10⁸ cells/ml), monomethylamine (B) (cell density = 1.8 × 10⁸ cells/ml), or glucose (C) (cell density = 3.4 × 10⁹ cells/ml). Symbols: ●, untreated cell suspensions; □, cell suspensions incubated with chloramphenicol. Symbols represent the mean of three suspensions, and bars indicate ±1 standard deviation. Absence of bars indicates that the error was smaller than the symbols.
