Bioethanol Producing Efficient Renewable Feedstock Production By Bacterial Isolates From Compost Soil

Efficient ethanol production requires the addition of expensive process and on other hand biofuels from renewable feedstock has seen large scientific interest since they could be used to supply energy and alternative fuels. Bioethanol is one of the majority exciting biofuels due to its optimistic impact on the environment. To reduce the production cost of ethanol by using feedstock, a study on how to produce ethanol efficiently by adding feedstock from waste paper, grass and dry leaves. Bioethanol mostly produced from sugar- and starch-containing raw materials. Various available types of lignocellulosic agro wastes and its product such as grass, dry leaves and waste paper was pre treated for the production of fermentable sugars by enzymatic digestion of microbe which is isolated from compost soil. The bacterial isolated were identifying through biochemical test and staining procedure. The enzyme cellulase activity analyses by Miller method using glucose as standard. The digestive feedstock from various lignocellulosic materials enhances in the ethanol production by Saccharomyces cerevisiae. The ethanol production is higher in using feedstock from waste paper, grass and dry leaves was comparable with added nutrients (yeast extract and peptone) and pH adjustment using H2SO4, indicating that waste paper is not only a carbon source but also an excellent nutrient source act as a feedstock for the ethanol production by Saccharomyces cerevisiae. Waste paper is considered as one of the major components of municipal and industrial wastes and has the potential to be used as an excellent alternative feedstock for ethanol production.
