heal.abstract	Olive oil mill solid residues (OMSR) is the solid waste generated during olive oil production process inthree-phase olive mills. It consists of the remaining pulp of olive processing, after the extraction of oil, as well as the cracked seed of the olive fruits, containing thus mainly lignocellulose and residual oil. The commonly used practice for OMSR management is combustion, after having extracted the residual oil by secondary extraction using organic solvents. Other proposed ways of OMSR management are their exploitation as substrate for edible fungi production and compost, and as feedstock for biofuels generation such as bioethanol and methane. In the latter case, the complex carbohydrates (cellulose and hemicellulose) of the lignocellulose of OMSR have to be degraded towards their simple sugars and further fermented via microorganisms. The purpose of the present study was to investigate the effect of thermochemical pre-treatment of OMSR, on the final ethanol yield from the yeastPachysolentannophylus. Nine different types of OMSR-based substrates were tested i.e. raw OMSR, hydrolysates generated from pretreated OMSR with NaOH (0.5%, 1.5% w/v) and H2SO4 (0.5%, 1.5% v/v), and pretreated OMSR with NaOH (0.5%, 1.5% w/v) and H2SO4 (0.5%, 1.5% v/v) whole biomass. It was shown that in all cases pretreatment enhanced both carbohydrates' consumption and ethanol final yields. © 2012 Global NEST.	en
