Screening for Plasmids in Halophiles

Abstract

Seven strains of halophiles that are associated with organophosphorus acidic (OPA) anhydrase activity were screened for the presence of plasmid DNA. Only one out of seven showed evidence of plasmid DNA. The presence of this particular plasmid DNA was not correlated with antibiotic resistance. The results suggest that the gene that codes for OPA anhydrase is located on the chromosomal DNA. The information obtained in this study will be useful for the cloning of OPA anhydrase gene(s) of these halophiles.
