Biogeochemistry Division

Research

• Determination of speciation and solubility properties of radionuclides relevant to the environment
• Verification and validation of solubility and transport models for the above cases
• Characterization of particles in the environment relevant to the transport of radionuclides.
• Investigation of the transport process of radionuclides by particles in natural water.
• Bacterial diversity in water and soil environments contaminated with heavy metals and radionuclides:
  a) Direct molecular DNA analysis (rep-APD, RISA, 16S-rDNA retrieval).
  b) Characterization of natural bacterial isolates recovered from uranium mining waste piles and belonging to the genera Bacillus, Desulfovibrio, Leptospirillum, and Thiobacillus using ARDREA, RAPD, rep-APD, PFGE and 16S- and 23S-rDNA sequence analysis.
• Bacterial-metal interactions:
  a) Biotransformation and bioaccumulation of heavy metals and radionucides by bacteria
  b) Tolerance of bacteria to different heavy metals
  c) Analysis of the genetic determinants responsible for the bacterial-metal interactions
  d) S-layers of bacteria recovered from uranium mining waste piles: structure and metal clustering
• Interaction of eukaryotic cells with f-elements (radionuclides and heavy metals)
• Fungi, sponges, algae

Experimental methods

• Microscopy: CLSM; REM; TEM
• Spectroscopy: LIS (TRLFS, LIPAS); XAS
