Abstract

Ethanol serves as the best alternative energy resource. Xyloglucan, a major polysaccharide in tamarind seed had to be broken down for the release of monomers which could be used as substrate for ethanol production. Tamarind Kernel Powder (TKP) was subjected to various pretreatment methods like acid treatment and physiochemical treatment for the breakdown of xyloglucan where 31.9g/l and 41.7g/l of reducing sugars were released respectively. The acid treated hydrolysate was detoxified to remove the inhibitory compounds and then subjected to fermentation by Pachysolen tannophilus. It was found that 11% of ethanol was produced from acid pretreated TKP.
