摘要：

The fermentation of milk inoculated with bacteria was monitored amperometrically using an L-lactate biosensor and a flow-injection system. This approach was compared with the measurement of pH. The effects of Enterococcus faecalis, Bacillus coagulans, Enterobacter sakazakii, Staphylococcus aureus, and Bacillus sphericus were investigated. The most promising results were obtained for Staphylococcus aureus, whose fermentation increases milk pH.
