3.3. Optimization of ethanol fermentation in Erlenmeyer
flask
The effect of temperature on ethanol fermentation in a
basal sugar cane juice medium by the four strains, DMKU
3-1042, DMKU 3-118, DMKU 3-p106 and DMKU 3-
p1042, was investigated. Maximal ethanol concentrations
produced by these four strains at 30 and 37 C were in
the range of 7.13–7.6% (w/v) (Fig. 1). The productivities
of DMKU 3-118 and DMKU 3-1042 were almost the same
at 30 and 37 C while those of DMKU 3-p106 and DMKU
