Researchers from the Department of Chemical Engineering, Lund University (Sweden) and the Department of Applied Biotechnology and Food Science, Budapest University of Technology and Economics (Hungary) report the production of biofuel ethanol using a mixture of First Generation (1G) and Second Generation (2G) feedstocks. The 2G feedstock (consisting of steam pretreated wheat straw, PSW) was mixed with a 1G feedstock (pre-saccharified wheat meal, PSM) and was subjected to a simultaneous saccharification-fermentation (SSF) process for ethanol production. Results showed that the ethanol yield was higher in the 2G-1G mixture, compared to those using the 2G feedstock (PSW) alone, or the 1G feedstock alone (PWM). The researchers concluded that "mixing wheat straw with wheat meal would be beneficial for both 1G and 2G ethanol production", but certain areas (such as more effective utilization of the xylose fraction) can be investigated for further improvement of the process. The complete results are published in the open-access journal, Biotechnology for Biofuels (URL above).
