Produção de bioetanol de segunda geração a partir da Biomassa lignocelulósica - casca e polpa de Banana

Abstract

The demand for new raw materials and processes to obtain fuels has grown at the same pace as society has developed. In modern modern society, fuels are widely used in the operation of industrial machinery, automobiles, domestic cookers, fireplaces and in various areas that need fuels for the development of their activities. The production second-generation ethanol, produced from previously unused plant waste, is a clear used, clearly exemplifies this need, and new sources are being tested and discovered for obtaining bioethanol. The present work highlights the results of an investigation, which had as its the main objective of which was to obtain bioethanol from banana crop residues (banana pulp and peel). It is concluded that by fermenting banana peel or pulp and using the yeast sacharomyces cerevisiae as fermenting microorganism is possible to obtain bioethanol. The higher the sugar content present in the biomass the greater the amount of ethanol produced in its fermentation, but only possessing a biomass with a high sugar content is not enough to guarantee the success in bioethanol production. It is necessary that fermentation occurs under optimum optimum conditions of pH, temperature and the choice of an efficient microorganism for fermentation. (TRADUÇAO NOSSA)
