A bacterial consortium isolated from soil samples with a history of Temik application was tested for its ability to utilize Temik, purified Temik, and analytical-grade aldicarb as the sole sources of carbon and energy. Five bacterial isolates were obtained in pure form, one of which was very effective in utilizing 0.005-01% (w/v) aldicarb within a duration of from two to six days. Both the bacterial consortium and the single bacterial isolates yielded an unidentified metabolic by product of aldicarb in the growth media.
