Aspectos taxonómicos de cepas patagónicas y cepas tipo del genero Desulfovibrio / [Taxonomic aspects of strains from Patagonia and type strains of Desulfovibrio]

ABSTRACT

Fourteen type strains and 42 indigenous strains of Desulfovibrio were studied and taxonomic numeric methods were applied (Cluster Analysis, Principal Coordinates Analysis, Correspondence Analysis). The type strains as well as the indigenous ones share a low quantity of carbon and energy sources. Type strains have a taxonomic structure which shows net clusters; indigenous strains possess a grading (or [quot ]adjustment[quot ]) in their positive reactions hence the taxonomic structure is not so clear. Both classifications are firm since they suffer minimal changes when they are joined.
