Ribosomal rRNA gene fragments (rDNA) encompassing the 16S rDNA, the 16S–23S rDNA spacer region and part of the 23S rDNA of 95 strains belonging to 13 well‐described taxa of the eubacterial family comamonadaceae (β subclass of the Proteobacteria or rRNA superfamily III) were enzymatically amplified using conserved primers. The fragments of approximately 2400 base pairs were subjected to restriction analysis. Restriction fragment length patterns obtained with Hin fI enabled us to distinguish 9 of the 13 taxa studied. Restriction with Cfo I was necessary to differentiate Acidovorax delafieldii from A. temperans and Hydrogenophaga flava from H. pseudoflava . The results indicate that amplified rDNA restriction analysis is a simple and reliable tool for the identification of bacterial species.
