Abstract

Formate, or compounds convertible into formate, is determined by reacting same in the presence of formate dehydrogenase (FDH) and of a hydrogen acceptor, e.g., NAD, wherein the formate dehydrogenase is from Candida boidinii DSM 941, to result in stoichiometric reactions. The process can be used for the removal of formate from solutions containing same.
