In a study on ethanol production in a 5 l jar fermenter
with an agitation speed of 300 rpm and an aeration rate of 0.2 vvm throughout the fermentation, K. marxianus DMKU
3-1042 yielded a final ethanol concentration of 6.43% (w/v), a productivity of 1.3 g/l/h and a yield of 57.1% of theoretical yield
