Investigation Of Tile Potential Of Some Moisaic Disease Resistance Cassava Genotype For Ethanol Production.

ABSTRACT

 This project was aimed at investigating the potential of some moisaic disease resistance cassava genotypes for ethanol production. The two cassava mosaic diseases (CMD) resistance varieties were TME 419 and 8082 which were recently developed by National Root Crops Research Institute Umudike and the last variety Nwaibibi is a local variety. They were peeled, washed, grated, sieved, sediment and dried by sun drying to obtain the starch. The starch samples obtained were analyzed for starch content, moisture, protein, fat, ash ,crude fiber and carbohydrate. The cassava starch samples were first hydrolyzed using degrading enzymes which included amylase, amyloglucosidase and fungamy and fermentation was carried out using a yeast strain, saccharomyces cerevisae. The cassava variety 8082 had the highest yield of ethanol( 9.60%) at the 8th day while Nwaibibi gave 8.80% at the 10th day and TMIE419 gave 8.27% quantity of ethanol at the 12th day.
