摘要：

Three biosensor configurations that included a dissolved oxygen electrode and yeast cells (Saccharomyces cerevisiae) were evaluated as a means to assess the environmental effects of toxic chemicals. The configurations were: closed suspension-assay medium closed to air and cells suspended in the medium; open suspension-assay medium open to air and cells suspended in medium; and biofilm electrode (BFE)-assay medium open to air but cells immobilized on the surface of the electrode. The BFE was the most advantageous configuration based on assay times and detection limits.
