Sažetak
Finding the alternative energy sources that will efficiently replace fossil fuels has been of tremendous scientific and public interest in recent years. Degradation of lignocellulosic materials, like herbaceous sugar beet waste- a sugar beet industry by-product, and use of its degrading products as substrate for biofuels production may be one of the alternatives. The composition of sugar beet pulp is as follows: 75- 80 % carbohydrates, 1-6 % lignin and 10-15 % proteins. Hemicellulose, one of the major constituent of plant material is therefore convertible to bioethanol through hydrolysis and fermentation processes. Hemicellulose is a type of hetero-polysaccharide, containing glucose, xylose, mannose, galactose, arabinose, fucose, glucuronic acid, and galacturonic acid in various amounts depending on the source. Pentosan group is composed of 5C hemicellulose sugars. The aim of this study was to investigate the pentosans utilisation possibility of different white-rot fungi. Trametes versicolor exhibited the best pentosans degradation capacity, with only 3.75 % of pentosans in dry matter determined at the end of fermentation.
