Methods and equipment for the bioelectrochemical cell measurement of microbial activity.

摘要

A method of monitoring microbial activity in an aqueous analyte sample, which comprises combining a known volume of the sample with lyophilized bioelectrochemical cell components in a cell and measuring an electrical signal from electrodes in the cell. The use of lyophilized BEC components eliminates dilution of the sample, stabilizes the BEC components (e.g. ferricyanide), and increases the speed of response since the reagents rehydrate almost immediately.
