Figure 9: Images of agarose gels showing results of PCR for the detection of genes related to lipopeptide biosurfactants production (sfp0 and srfA) and catechol dioxygenase in some isolates. Genomic DNA isolated from different bacteria was used as a template. Genomic DNA from B. subtilis was used a positive control for the sfp0 and srfA. Control runs are PCR runs without template DNA.
