Isolation of a new broad-host-range IncQ-like plasmid, pTC-F14, from the acidophilic bacterium Acidithiobacillus caldus and analysis of the plasmid replicon.

Abstract

A moderately thermophilic (45 to 50 degrees C), highly acidophilic (pH 1.5 to 2.5), chemolithotrophic Acidithiobacillus caldus strain, f, was isolated from a biooxidation process used to treat nickel ore. Trans-alternating field electrophoresis analysis of total DNA from the A. caldus cells revealed two plasmids of approximately 14 and 45 kb. The 14-kb… (More)
