This lab is specialized on radioisotope tracer studies involving direct measurements of the turnover or incorporation of radioactively labelled compounds. The following radiotracer techniques are employed: measurement of sulfate reduction rate with ³⁵S radiotracer, methanogenesis rate with ¹⁴C radiotracer, and methane oxidation rate with ¹⁴C radiotracer. The laboratory equipment includes a distillation setup for reduced sulfur species, a high-pressure thermal gradient incubation system, a …
