FIG. 2.

Time course experiment to determine WST-1 reduction in the presence and absence of the electron donors glucose, succinate, and pyruvate (16.6 mM each). Mycobacterium (Myc.) and Sphingomonas (Sph.) cells were grown in microtiter plates with PAHs as sole sources of carbon and energy. The error bars represent ±1 standard deviation. Symbols: ▵, PAH plus e-donors; □, PAH with no e-donors; ○, no PAH but with e-donors.
