Plasmid DNA profiles in Thiobacillus ferrooxidans.

Abstract: Thiobacillus ferrooxidans is a gram-negative, acidophilic, chemolithotrophic bacterium oxidizing ferrous to ferric ions and reduced sulfur compounds to sulfate. These unusual physiological features enable this bacterium to play an important role in the leaching of metals from low grade ores (8). The metabolism of T. ferrooxidans is fairly well known, while studies on its genetic organization started only a few years ago and are still in progress. Plasmid occurrence in this species has been shown since 1980 (2)… Show more

“…The finding that backbones of plasmids isolated from different strains of S. thermotolerans from different geographical locations are related but that the accessory genes are different appears to be a recurring theme in iron-and sulfuroxidizing bacteria. Species-specific plasmid backbones have been reported in Acidithiobacillus ferrooxidans (7,12,43), and Acidithiobacillus caldus (44). In A. caldus and S. thermotolerans, these plasmids appear to be either mobilizable or conjugable and may be involved in the movement of the accessory genes within isolates of the same species and possibly also between species.…”

“…In a survey of more than 100 strains from six Japanese mining sites, 73% were found to carry one or more plasmids ranging in size from 2.0 to 30 kbp (131). Plasmids have also been reported in strains from South Africa (109), Italy and Mexico (145), Chile (124), and Canada (87). In the Canadian study, one to four plasmids of 18.6 to 65 kbp were detected in nine T. ferrooxidans strains isolated from the Agnew Lake uranium mine, northern Ontario.…”

“…These strains, isolated from a different geographical and geochemical site, had a different colony morphology and a well-defined plasmid content which differed from the plasmid content of TFFC [20]. At the first passage in sulphur liquid medium, the growth rate of TFOB and TFGO2 was low and only after three serial passages these strains produced biomass sufficient to examine their OMP profile.…”
