A strain of Pseudomonas aeruginosa (OB-6) isolated from biodeteriorated water-based paint samples was screened for its plasmid profiles and antimicrobial susceptibility patterns. The organism possessed two plasmids which ranged in molecular sizes from 0.030 to 0.112 kilobases (kb). Antimicrobial resistance patterns showed resistance to Tobramycin, Amikacin, Gentamycine and industrial biocides ZN467 and ZN489. After curing experiments with 0.002% (v/v) sodium dodecyl sulphate (SDS), the organism was observed to have lost the two plasmids and the resistance to Tobramycin, Amikacin and Gentamycin. The organism therefore, seemed to bear plasmids that encoded genes for deterioration and antibiotic resistance as determined by the curing experiments. A comparison of the biodegradative potential of the wild and the cured strain on the physico-chemical properties of fresh, sterile paints showed the wild strain to have 25% degradative potential, while the cured strain had 17% degradative potential.
