Abstract

A sociedade é atualmente desafiada a conciliar a crescente demanda de energia com irrefutável necessidade de sustentabilidade. O esgotamento progressivo dos combustíveis fósseis e as emissões de gases de efeito estufa motivam o emprego de fontes de energia de caráter renovável, sustentável e de baixo custo. Nesse contexto, o etanol de segunda geração tem sido apontado com alternativa aos combustíveis derivados do petróleo, uma vez que é obtido a partir de biomassa lignocelulósica. A efetiva aplicação dos materiais lignocelulósicos requer etapas de pré-tratamento que promovem o fracionamento dos seus principais constituintes (celulose, hemicelulose e lignina). A combinação de diferentes tipos de pré-tratamentos é explorada visando aumento da recuperação dos açúcares e a mínima liberação de substancias com potencial ação inibitória ao metabolismo microbiano, que afetam a eficiência e produtividade do processo fermentativo. Esta breve revisão de literatura apresenta as principais tecnologias envolvidas no processamento da biomassa lignocelulósica para produção de etanol.
