Abstract

A new species of ferrous-iron-oxidizing, moderately thermophilic, acidophilic bacteria, , has been described. Two isolates of the species differed only in the tendency of one, previously known as strain TH3, to grow in filaments. The chromosomal DNA base composition is between 67 and 69 mol% G + C. The capacity of this species to fix CO from air was greater than that of iron-oxidizing thermoacidophiles of the genus , which required an enhanced CO concentration for optimum autotrophic growth. Under air, ferrous iron oxidation in mixed cultures of with either or was more extensive than in pure cultures of these three strains. The greater part of ferrous iron oxidation in mixed cultures probably resulted from activity of the species, which possess a greater tolerance of ferric iron, and which presumably grew mixotrophically utilizing organic compounds from .
