Phylogenetic relationships established by the maximum-likelihood method (using MEGA6 software) based on 16S rRNA gene sequences of isolated bacterial strains (SDZ-PM2-BSH30, SDZ-W2-SJ40, and SDZ-3S-SCL47).
Scale bar, no. of nucleotide changes/sequence position. The number at nodes shows the bootstrap values obtained with 1,000 resampling analyses.

SDZ (5 mg L-1) degradation by SDZ-PM2-BSH30 (a), SDZ-W2-SJ40 (b) and SDZ-3S-SCL47 (c).
Error bar represents the standard deviation of the triplicates.

2-Aminopyrimidine (5 mg L-1) degradation by SDZ-PM2-BSH30 (a), SDZ-W2-SJ40 (b) and SDZ-3S-SCL47 (c).
Error bar represents the standard deviation of the triplicates.

Quantitation of the chemotactic response and determination of optimal response concentration for Paracoccus sp. SDZ-PM2-BSH30 (a), Methylobacterium sp. SDZ-W2-SJ40 (b) and Kribbella sp. SDZ-3S-SCL47 (c) towards 2- aminopyrimidine using capillary assay.
Error bar represents the standard deviation of the triplicates.

Chemotaxis of bacteria like SDZ-PM2-BSH30 (a), SDZ-W2-SJ40 (b), and SDZ-3S-SCL47 (c) toward 2-aminopyrimidine.
The bacterial cells were grown on SDZ and tested on 2-aminopyrimidine. Results were obtained by drop plate assays. The assays were performed in triplicate and the representative plates are shown here. Aspartate was used as the positive control.
