We isolated the 2,4-D-catabolizing bacterial strain RD5-C2 from Japanese upland soil that had no history of 2,4-D exposure. RD5-C2 could use 2,4-D as the sole carbon and energy sources for their growth. Phylogenetic analyses based on 16S rDNA sequencing revealed that RD5-C2 was a member of the BANA (Bradyrhizobium-Agromonas-Nitrobacter-Afipia) cluster in the α subdivision of the class Proteobacteria. The gene sequence of RD5-C2 most closely matched that of Bradyrhizobium sp. and also closely related to those of 2,4-D-catabolizing α-Proteobacteria previously isolated from pristine environments of Hawaii, northern Canada and central Chile. This is the first instance that 2,4-D-catabolizing bacteria in that phylogenetic group was isolated from an arable soil environment.
