Název v původním jazyce

Processing of wheat bran to sugar solution

Popis výsledku v původním jazyce

In accordance to better exploitation of raw material for bioethanol production we try to find the method for saccharification of problematic cover part of grain, so called bran. The bran consists of three main components: residual starch, hemicellulose and cellulose. Whereas hydrolysis of starch is easy and well solved, there are questions how to optimise hydrolysis of all polysaccharides together, including hemicellulose and cellulose. The bran was treated with starch degrading enzymes (Termamyl 120 Land AMG 300 L) in order to remove the starch from the solid particles and use the starch-free residue for hydrolysis of hemicelluloses to pentoses. This starch-free residue (SFR) was treated with sulphuric acid and high temperature during exact time. Different times of pre-treatment (10-50 min), different temperatures (110-180 _C) and different concentrations of sulphuric acid (1-4% of weight of slurry) were tested, as well as presence of furfural and 5-hydroxy-methyl-2-furaldehyd (HMF),
