The second stage involves feeding the acetate produced in the first stage into a reactor, where it is mixed with aerobic bacteria, which uses the acetate to produce a single-cell protein.

The system consists of two interconnected reactors: the first uses microbial electrosynthesis (MES) to convert CO2 into acetate, while the second employs aerobic bacteria (*Alcaligenes*) to ...

The equation for this is: glucose → lactic acid Anaerobic respiration releases less energy than aerobic respiration but it does this more quickly. The product of this reaction is lactic acid.
