Fig. 4. 16S rRNA gene-based denaturing gradient gel electrophoresis community analysis of indigenous eubacteria (lanes 1–10) and indigenous Sphingomonas spp. (lanes 11–18) in soil for the AndE soil experiment. Lanes 1, 3, 5, 7, 9: eubacterial fingerprints for control soil (C) after 0, 21, 35, 126, and 252 d of incubation, respectively. Lanes 2, 4, 6, 8, 10: eubacterial fingerprints for extracted soil (E) after 0, 21, 35, 126, and 252 d of incubation, respectively. Lanes 11–14: Sphingomonas fingerprints for control soil after 0, 21, 35, 126 d of incubation, respectively. Lanes 15–18: Sphingomonas fingerprints for extracted soil after 0, 21, 35, 126 d of incubation, respectively.
