Notes:
It has been found that a bacterium (isolant C12B) grew poorly on 6 and 8 carbon alcohols, well on 10 and 12 carbon alcohols, and slowly but well on the 14 to 18 carbon compounds. Unexpectedly, resting cells oxidized the 6 and 8 carbon compounds most readily and cell-free extracts oxidized 6, 8, and 10 carbon alcohols. Extracts from cells adapted to sodium lauryl sulfate oxidized the 12 carbon alcohol as well, if small concentrations of substrate were used. The bacterium grew on benzene sulfonate and adapted resting cells oxidized that compound. Pure culture degradation studies revealed that isolant C12B used only 11% of tetrapropylene ABS supplied as a sole carbon source, whereas 66% of sodium lauryl sulfate was degraded. Intermediate quantities of kerosene-based alkyl benzene sulfonate and a tallow-derived detergent were utilized. Extracts of another bacterium, TEG-5, grown on tetraethylene glycol, contained enzymes which oxidized polyethylene glycols up to an average molecular weight of 600, but not any larger polymers. This oxidation was visualized by coupling to reduction of ferricyanide.
