Abstract
Microorganisms of the genus Thiobacillus find utility in the mining industry in such applications as bacterial leaching, the treatment of mine drainage water and the deiron in hydrometallurgy process. This invention discloses a DNA fragment which codes for a mercuric reductase in microorganisms of the genus Thiobacillus and is useful in constructing a new strain of Thiobacillus ferrooxidans capable of fast growth. A recombinant plasmid incorporating the DNA fragment, a shuttle vector plasmid incorporating the DNA fragment, host cells and a method of transforming the host cells are also disclosed.
