| dc.description.abstract | The work is at investigated the potential of cheap raw materials as substrates (sawdust, rice straw and maize straw) for the production of bioethanol. Lignocellulosic substrates were hydrolysed using Pleurotus tuber-regium for 42 days. Samples were taken every 14 days and production of lignin, hemicellulose, cellulose, pH, reducing sugar and total solids were determined. Hydrolysates of lignocellulosic substrates were fermented using Saccharomyces cerevisiae and Baker's yeast for 10 days in with pH, reducing sugar and ethanol content determined at 2 days interval. Effect of supplementation (maize pomace and corn steep liquor) on pH, reducing sugar and production of ethanol were determined every 2 days for 10 days. Significant decrease in lignin and cellulose content was recorded in some samples while the hemicellulose content decreased in all the samples hydrolysed with increase in incubation time. Sawdust from Amphimas pterocarpoides (SD1) and Rice straw (RS) had highest (21.50%) and lowest (5.94%) lignin content respectively. Maize Straw (MS) had the highest hemicellulose content (25.37%) and lowest cellulose content (42.90%). Total solid significantly increased with increase in incubation time. The highest ethanol content (1.8%) was recorded on the 2nd day of fermentation in filtrates from unsupplemented substrates (sawdust from Ceiba pentandra (SD2) and Maize straw) fermented with Saccharomyces cerevisiae. Ethanol production was higher in unsupplemented substrates (1.8%) than supplemented substrate (0.9%). Reducing sugar and pH decreased with increase in fermentation time. Substrate supplemented with corn steep liquor produced higher quantity of ethanol than substrates supplemented with maize pomace. Hydrolysates from untreated maize straw (MS) fermented with Saccharomyces cerevisiae, Baker's yeast and the coinoculation of both within the range of 3.7 – 6.0 for 2 days can be used for bioethanol production. Likewise, filtrates from treated sawdust from Ceiba pentandra (SD2) fermented with Saccharomyces cerevisiae, Baker's yeast and the co-inoculation of both within the pH range of 4.3 – 5.4 for 2 days can also be used for bioethanol production but appreciable quantity can be produced from untreated (autoclaved)MS with Saccharomyces cerevisiae(Baker's yeast)only. | |
