FIG. 2.

Mineralization of [¹⁴C]octadecane and [¹⁴C]dodecane by Mycobacterium sp. strain CH1. Cells were pregrown on acetate in the presence (□, ○) or absence (■, •) of octadecane. Cells were added to triplicate bioreactors at an initial concentration of 0.10 absorbance unit at 600 nm. Mineralization was measured by the evolution of ¹⁴CO₂, as described in the text. □, ■, mineralization of octadecane; •, ○, mineralization of dodecane.
