    Production of Cellulosic Ethanol from Wood Sawdust by Sulphuric acid Hydrolysis

    By Gebreyohannes Gebrehiwot, Sekarathil Anuradha Jabasingh, Abubeker Yimam

    Abstract: In this study, production of cellulosic ethanol from wood sawdust was investigated. Four experimental parameters were investigated during the hydrolysis and ethanol production. These are particle size (1–3 mm), acid concentration (3–7%), temperature (90–110°C), and time(120–240 min). The total reduced sugar content and ethanol yield was determined. Response surface methodology (RSM) employing the central composite design (CCD) was used to optimize the total reduced sugar and ethanol yield. Cite this …

    Extraction and Characterization of Antioxidants from the Seeds of Ethiopian Avocado Variety, Pinkerton

    By Azeb Tibebu, S ANURADHA JABASINGH, Abubeker Yimam

    Abstract: The objective of this study was to extract and characterize the antioxidants from the Ethiopian avocado seeds of the Pinkerton variety, using ethanol as a solvent. Response surface methodology (RSM) in combination with Box-Behnken experimental design with a three level, three-factor mixture design was used to optimize the extraction condition for assessing the maximum yield of antioxidant from the avocado seeds. Ethanol concentration (%, v/v), temperature (°C) and time (h) …
