Physico-chemical characteristics of plasmid DNAs isolated from P. putida G7 and the behavior of these DNAs in chromatography on columns with Sepharose 4B and kieselguhr with methylated albumin (MAC) were studied. This strain contained several plasmid DNAs having MW of 33-36 .times. 106, 15-18 .times. 106 and 3-5 .times. 106 daltons. The plasmid DNAs of biodegradation are apparently located in the vicinity of chromosomes and only a small part of them is characterized by extrachromosomal localization.
