Özet
Pre-treatment of biomass is of great importance to maximize the recovery of fermentable sugars and minimize the amount of enzyme inhibitors formed. There are several processes that can be applied for pre-treatment of agricultural industrial waste such as chemical, physical, physico-chemical, biological, and combined pre-treatments. Alkaline hydrogen peroxide (AHP) and ultrasonication are two of this pre-treatment process. The aim of this study was to investigate the pre-treatment performance of barley straw biomass using AHP and combined ultrasonic-hydrogen peroxide process via Box-Behnken design as a response surface methodology (RSM). The factors of time (30-120 min), particle size (0.2-1 mm), peroxide dosage (1-5%), and temperature (50-100 degrees C) are investigated for optimum operating conditions. For ultrasonication process, factors are time (5-30 min), particle size (0.2-1.0 mm) and US power (20-100 Kj/kgDM). During AHP pre-treatment, maximum total and reduced sugar concentration was found as 14 g/L and 660 mg/L, respectively, at maximum level of time and minimum level of dosage factors which are 120 min and 1%, respectively. Maximum total and reduced sugar concentration can be reached nearly 7.6 g/L and 810 mg/L, respectively, at minimum level of time which is 5 min and almost minimum level of chemical dosage in ultrasound-hydrogen peroxide process, respectively.
