Abstract
The potential of by-products and intermediate products of sugar beet processing as rawmaterials for bioethanol production in Serbia has a big scope in view of the demand of ethanol as an alternative for fossil fuels. The production of bioethanol from sugar beet thin juice by Saccharomyces cerevisiae immobilized on sugar beet pulp (SBP) enables one more opportunity for achieving the zerowaste goal, through a rational use of intermediate and by-products of sugar beet processing. The effect of inoculum concentration on volatile compounds content of distillate was examined. The increase of inoculum concentration from 2.0 g/1 to 2.6 g/l (dry mass basis) increased ethanol and aldehyde content of the distillate from 9.34 % v/v to 9.60 % v/v and from 238.6 mg/l a.a. to 301.5 mg/l a.a., but decreased methanol, acetic acid and ester content from 650.0 mg/l a.a. to 232.3 mg/l a.a., from 73.4 to 51.3 mg/l a.a., and from 272.0 mg/l a.a. to 220.8 mg/l a.a., respectively. The increase in inoculum concentration of SBP-immobilized yeast indicated improvement of distillate quality.
