Bioleaching of polymetallic sedimentary ore (Id 168)

No current offer!

At the Helmholtz -Zentrum Dresden Rossendorf (HZDR) special effects of bioleaching in polymetallic sedimentary deposits with different mineral structure will be investigated in the framework of an industrial research project. In a first stage, the microbial population in the original formation should be determined. The microorganisms in samples of both ore and formation water are identified by DNA isolation and 16S rDNA sequencing. Bioinformatics enable to conclude from the sequencing results to potential enzymes, in particular, oxidoreductases for the catalysis of oxidative leaching effects
Leaching experiment for simulating the in-situ recovery of metals result in samples of the (metal-bearing) leach solution and of the remaining ore. These samples will be systematically investigated by the use of DNA fingerprint techniques and 16S rDNA sequencing to identify changes caused by bioleaching.

Detailed work tasks include:

  • DNA isolation
  • DNA fingerprints
  • 16S rDNA sequencing
