Abstract

Guanine-plus-cytosine (G+C) content determinations, deoxyribonucleic acid (DNA) relatedness estimations, and phenotypic similarity analyses of 90 strains identified previously as Hammer 1915 revealed that 52 (group 1) strains were sensu stricto; 30 of the remaining organisms segregated into two distinct DNA relatedness groups, one consisting of 26 (group 2) strains and the other of 4 (group 4) organisms. Five (group 3) strains were , and three (group 5) strains were Because group 2 was a major cluster of strains which did not correspond in their characteristics to any previously known group, efforts were made to determine its taxonomic position. Group 2, with G+C contents ranging from 37 to 40 mol%, was compared with other species generally characterized as having G+C contents ranging from 37 to 44 mol% or capable of growing at 50°C or both (namely, Low DNA relatedness values and poor matching of phenotypic characteristics strongly indicated that group 2 organisms are strains of a new species, for which the name is proposed. The type strain of the new species is strain NRRL NRS-173.
