Novel mineral-oxidizing bacteria from Montserrat (W.I.): physiological and phylogenetic characteristics
Four mesophilic acidophilic bacteria isolated from the Caribbean island of Montserrat have been studied to establish their taxonomic relationship to other metal-metabolizing bacteria and to analyze their potential role in mineral processing. Two of the isolates have some physiological and morphological traits in common with Thiobacillus ferrooxidans (Gram negative, iron-oxidizing mesophilic rods) but differed from T. ferrooxidans in displaying chemolitho-heterotrophic growth in ferrous iron/yeast extract medium and greater sensitivity to some metals. Isolates RIV-14 and L-15 were, in contrast, Gram positive, spore-forming rods that displayed considerable metabolic flexibility, and resembled moderately thermophilic Sulfobacillus spp. All the Montserrat isolates were able to oxidize pyrite in pure culture.
