The yeast C. boidinii is capable of oxidizing a sufficiently broad
range of substrates except surfactants, branched alcohols, some disaccharides and lysine (Table 1). A characteristic feature of both P.angusta strains is their capability of actively oxidizing secondary and branched alcohols, which enables using the biosensor on its
basis for BOD assays of waste waters in liquor enterprises. The
receptor based on G. oxydans bacteria is characterized by the most
narrow range of oxidized substrates. Responses of a biosensor
based on these bacterial cells were obtained for normal structure
alcohols (except methanol), some carbohydrates and amino acids.
