Abstract

Biomass obtained from olive pruning has been torrified at different conditions, namely at 180 - 280°C for 60 -120 min. , grinded with mill having sieve of 50 mesh (0.32 mm), and used as substrate in SHF experiments. The bioconversion has been carried out at flask scale using a mix of cellulosolytic, hemicellulosolitic and ß­glucosidase enzymes, and a commercial strain of Saccharomyces cerevisiae. The comparison between the bioconversion yields achieved using grinded biomass or torrified + grinded biomass highlighted that: 1) Mild torrefaction conditions limit sugar degradation within 5-10 percent; 2) Torrified biomass do not lead to enzymatic and fermentation inhibition. How a torrefaction step could be integrated in an ethanol production process has been preliminary estimated, above all as regard the energy integration. The new developed concept has been patented.
