title: [Characteristics of Pseudomonas putida plasmid DNAs].
abstract: Physico-chemical characteristics of plasmid DNAs isoalted from Pseudomonas putida G7 were studied as well as the behavior of these DNAs in th eourse of chromatography on columns with Sepharose 4B and kieselguhr with methylated albumin (MAC). This strain was found to contain several plasmid DNAs having molecular weights of 33-36X10(6), 15-18X10(6), and 3-5X10(6) dalton. The plasmid DNAs of biodegradation are supposed to be located in the vicinity of chromosomes, and only a small part of them is characterized by extrachromosomal localization.
