Abstract

Summary: Organisms of a strain of and an strain, capable of decomposing 2:4-dichlorophenoxyacetic acid (2:4-D) and 4-chloro-2-methylphenoxyacetic acid (MCPA) respectively, have been obtained by growing cultures on peptone agar plates containing either 2:4-D or MCPA. Glucose did not prevent adaptation. Organisms of the strain were adapted to oxidize 2:4-D when grown on peptone agar containing either MCPA or 2-chloro-4-methylphenoxyacetic acid; they did not decompose MCPA. The effects of some related compounds on adaptation to 2:4-D by these bacteria were examined. Growth of the strain on peptone agar containing either 2:4-dichlorophenol or 5-chloro-2-cresol gave organisms which were adapted to oxidize both 2:4-D and MCPA as well as the inducing compound.
