Production of lignolytic enzymes by fungi in agri-industrial residues

Abstract

Sugarcane is one of the major cultures of Brazil, thus having the sugar industry a great representation of the country's development. Sugar farming activities generate a large quantity of by-products, bagasse and vinasse that have the ability to add value to production, depending on the sector in which they are employed. Lignocellulosic biomass, bagasse, can be used in different processes, by hydrolysis and release of cellulose and hemicellulose. The sugars obtained from hydrolysis of bagasse can be converted into second-generation alcohol or other compounds. The most efficient methodology to obtain the sugars is a pre-treatment of biomass and, later, enzymatic hydrolysis. Due to difficulties in obtaining the enzymes, since most is imported, the objective of this work will be the cultivation of fungi Phanerochaete chrysosporium Lentinula edodes in broth containing sugar cane bagasse and vinasse, for to obtain lignolitics enzymes (laccase and peroxidase enzymes).
