Screen-printed electrodes modified by glucose oxidase, alcohol oxidase, lactate oxidase and γ-amylase immobilized into cross linked bovine serum albumin gel were produced for application in monitoring fermentation processes. The analytical and metrological characteristics of biosensors based on the developed electrodes were determined. Samples of fermentation mass and alcohol products were assayed. Statistical analysis of the results showed the values of glucose, ethanol, lactate and starch contents, determined using the developed multi-channel system and by reference methods, to differ insignificantly.
