Abstract

Physical, chemical, and biological processes commonly discriminate among stable isotopes. Therefore, the stable isotope compositions of biomass, growth substrates, and products often carry the isotopic fingerprints of the processes that shape them. Therefore, measuring isotope fractionation by enzymes and cultures of autotrophic microorganisms can provide insights at many levels, from metabolism to ecosystem function. Discussed here are considerations relevant to measuring isotope discrimination by enzymes as well as intact cells, with an emphasis on stable one-carbon isotopes and autotrophic microorganisms.
