Production of Glucose and Bioethanol from spyrogyra africanus

In this research work the optimal conditions for glucose and bio-ethanol production from Spirogyra africana were studied. The Spirogyra africana samples collected from the Ahmadu Bello University Zaria Dam were dried milled and sieved to ≤ 125 µm and subsequently analyzed for carbohydrate content .Prior to hydrolysis a set of the samples was pre-treated with NaOH 0.5 1.0 and 2.0 % (w/v) another set was blanched for 5 minutes at different temperatures (30 oC to 100 ºC) while another set served as control (untreated). Aspergillus niger and Saccharomyces cerevisiae were used for saccharification and fermentation processes respectively.
