Petrographical and mineralogical analysis of coal after biological leaching [PDF]

Acta Montanistica Slovaca, 2000
For coal utilization the sulphur content is a decisive parameter for the quality of the coal. In many countries clean coal technologies have to be applied on the basis of regulations concerning fuel quality and emission standards for dust, CO, SO2 and ...

Production and Regeneration of Thiobacillus ferrooxidans Spheroplasts [PDF]

Applied and Environmental Microbiology, 1985
We investigated the production and regeneration of Thiobacillus ferrooxidans spheroplasts. Regeneration frequencies of up to 90% reversion were obtained. Attempts to transform T. ferrooxidans spheroplasts with a recombinant T. ferrooxidans plasmid were unsuccessful.

Cloning of a Thiobacillus ferrooxidans plasmid in Escherichia coli [PDF]

Journal of Bacteriology, 1984
Three separate plasmids of 6, 7, 16, and greater than 23 kilobases were purified from a single clone of Thiobacillus ferrooxidans ATCC 33020 grown in the presence of uranium. The 6.7-kilobase plasmid (pTf1) was cloned separately into the HindIII or BamHI site of Escherichia coli plasmid pBR322.
