Abstract

Forty-eight strains of isolated from hot springs in Yellowstone National Park, Wyomming, USA, and eight reference strains were subjected to a numerical taxonomic analysis using Gower's coefficient () with single and average linkage clustering. Two major groups were distringuished, which could be differentiated by colony morphology, ability to reduce nitrate and proteolytic activity. Cluster 1 contained YT-1, the type strain of the species, and cluster 2 contained authentic strains of and was recovered as a single member cluster. The mol% G + C of DNA from representative strains from each cluster was 64·4 to 66·8 for cluster 1, 62·2 to 67·1 for cluster 2 and 62·5 for
