Sažetak
In this investigation, the production of ethanol on the raw sugar beet juice as well as on the raw sugar beet chips was studied. For ethanol production on the raw sugar beet juice batch and fed batch cultivation techniques were used during research in the stirred tank bioreactor. However, batch ethanol production on the raw sugar beet chips was carried out in horizontal rotating tubular bioreactor. In both cases, Saccharomyces cerevisiae was used as a working microorganism. During batch ethanol production on the raw sugar beet juice ethanol yield was 59.89 g/L and efficiency 78.8 %, respectively. In fed batch process ethanol yield was 92.78 g/L and efficiency 93.4 %, respectively. At the same time, ethanol production in HRTB on the raw sugar beet chips with 16.7 % v/m (raw sugar beet chips) inoculum resulted in the highest ethanol yield of 54.53 g/L and efficiency 79.5 %, respectively. Obtained results also clearly show that both intermediates of sugar beet processing can be successfully used for ethanol production.
