PRODUCTION OF BIOETHANOL FROM TECTONA GRANDIS, PTEROCARPUS MARSUPIUM AND PAPER

Currently one of the world’s primary energy sources, fossil fuels are also causing an increase in environmental pollution. Besides pollution, these fossil fuels are also diminishing in quantities which increase the need for alternative fuels. This rising need lead to the development of alternative renewable energy resources. A diverse range of sources are available that can be efficiently utilized to produce biofuels, in this research we utilize Tectona grandis (teak wood), Pterocarpus marsupium (malabar kino)and paper as biomass sources to produce bioethanol using Saccharomycescerevisiae fermentation. These biomasses were said to be lignocellulosic substrates rich in cellulose, hemicellulose and lignin. Simultaneous saccharification and fermentation (SSF) are used to in the conversion of substrate to ethanol in which the polysaccharides in the biomass are converted into simple sugars by hydrolysis. After which Saccharomyces cerevisiae used these basic sugars for the development of ethanol by fermentation. A bioethanol yield of 14.1%, 10.81% and 7.5% was obtained from Tectona grandis ,Pterocarpus marsupium and paper respectively, which was analyzed using dichromate titrimetric method. Thebioethanol yield from Tectona grandis is predominantly when compared with other biomasses.
