Glycerol, 2,3-BD, and acetoin yields of the BD5_G1CtPDC1 strain (w/o Nox), and the BD5_G1CtPDC1_nox strain (25, 50, 100) in batch cultivation with bioreactor. Aeration conditions were controlled by ratios of mixed inlet gas at constant agitation speed of 500 rpm and air flow rate of 2 vvm: only air (w/o Nox and 100), 1:1 mixture of air and nitrogen gas (50), 1:3 mixture of air and nitrogen gas (25)
