  2. Microbial Geochemistry Laboratory

Microbial Geochemistry Laboratory

The laboratory is equipped with an autoclave for sterilization and and a two-level shaking table for growth of bacterial cultures. The latter is situated in a dedicated temperature-controlled room off the main laboratory.

We have TWO high speed (Sorvall RC-5B and RC6+) refrigirated centrifuges for separating cells from supernatants and there are also microfuges for low volume samples

The laboratory also contains an automated Metteler Toledo DL53 and a Malvern Nano ZS zetasiser for surface characterisation of cells and particles, and a Brucker Vertex 70 ATR-FTIR spectrometer

In addition, there is a bio-reactor for more specialised, controlled atmosphere (Eh, pH, T) experiments and microbial culturing, and a sterile BACKTRON anaerobic chamber

Analytical facilities housed in the lab include two HPLC ssystems (Dionex 500 with ED and conductivity detection, Waters 600 with conductivity and UV detection), a DOC/TOC/TON analyser (Shimazu) and a UV-Vis spectrophotometer

Two new ICP-AES systems have been installed, purchased with funds from NERC and the School of GeoSciences.
