[Spectrophotometric method of assessing molecular DNA-DNA hybridization applicable to bacteria of the genus Pseudomonas]

A variant of unisotopic optical DNA-DNA molecular hybridization method basing on the study of reassociation rate of DNA renaturation fragments is described. The choice of working part of the renaturation curve has been standardized. Using the species of Pseudomonas genus it has been shown that this method permits to obtain reproductive results.
