The effect of acetate as a glucose co-substrate on growth, lysine synthesis and experimental lysine yield from carbon substrates by Corynebacterium glutamicum RC 115 was investigated. It was found that low amounts of acetate, injected with a glucose-acetate pulse into the steady-state continuous culture in bioreactor, caused a slight decrease in the specific rates of glucose uptake and bacterial growth, but a significant increase in the cell specific rate of lysine synthesis and an increase in lysine yield. In contrast, acetate injected in high amounts was followed by a drastic decrease in the values of these parameters. A strong increase in experimental lysine yield under the latter conditions was reached in the response to pyruvate addition. Therefore it was shown that acetate in low concentrations can be used as a glucose co-substrate to increase the cell specific rate of lysine synthesis and lysine yield by C. glutamicum RC 115. Pyruvate supplementation was found as a promising method to enhance lysine synthesis by bacterial cells grown in glucose-acetate media with an increased concentration of acetate.
