FIG. 3.

Requirement of new protein synthesis for the degradation of propylene and epoxypropane by N. corallina grown with glucose as the carbon source. Assays were conducted in 150-ml serum bottles containing 15 ml of glucose-grown cells (A₆₀₀ = 1.47) or propylene-grown cells (A₆₀₀ = 0.93) that had been transferred from 200-ml cultures grown in shake flasks. Closed symbols, assay bottles containing chloramphenicol (10 mg) and rifampin (5 mg); open symbols, assay bottles without chloramphenicol or rifampin present; circles, propylene-grown cells; squares, glucose-grown cells. (A) Propylene remaining; (B) epoxypropane remaining.
