Abstract
Increasing concern about the environment, food and feed shortages and hike in the price of petroleum have stimulated interest in new ways of producing more bioenergy. The interest is rapidly increasing towards converting agricultural and industrial wastes to commercially valuable products. Waste disposal and pollution are inextricably linked. The majority of waste disposal situations involve pollution of various kinds. Thus the solid wastes and its disposal is one of the serious problems in developing countries which require eco-friendly treatment options. The Bioethanol made from waste biomass can offer immediate and sustained greenhouse gas advantages and also solve the problem of its disposal. Citrus processing waste, a byproduct of juice manufactures which contains high amount of flavonoids and polysaccharides. There is a considerable industrial interest in the enzymatic transformation of flavonoids to hydrolysis products; that offers a pathway to bio-energy generation. Rhamnosidase of bacterial origin are very few and thus are potentially subject for research. Important sugars from the processed citrus peel waste were recovered by enzymatic hydrolysis and dilute acid treatment of the waste substrate further utilized for bioethanol production. Sacchromyces cerevisae was immobilized and used for simultaneous saccharification and fermentation. Bioethanol production was optimized and estimated by HPLC. Pectin was recovered as byproducts after the process. This method is an effort to develop an enzymatic treatment which would facilitate the economical processing of citrus waste for bioenergy generation. The process also holds the potential to reduce the environment threats by replacing the non renewable fuel and waste disposal issues.
