Abstract

"PROCEDIMENTO PARA A PRODUçãO DE ETANOL A PARTIR DE BIOMASSA LIGNOCELULóSICA". Ele inclui os estágios de triturar a biomassa lignocelulósica a um tamanho de 15-30 mm, submeter o produto obtido a pré-tratamento de explosão com vapor a uma temperatura de 190-230<198>C, durante entre 1 e 10 minutos, em um reator (2), coletar o material pré-tratado em um ciclone (3) e separar as frações líquida e sólida por filtragem em um filtro-prensa (9), introduzir a fração sólida em um depósito de fermentação (10), adicionar uma celulase a uma concentração de 15 UFP por grama de celulose e 12,6 Unidades Internacionais de enzima <225>glucosidase dissolvidas em tampão citrato pH 4,8, inocular o depósito de fermentação (10) com uma cultura da bactéria tolerante a calor Kluyveromyces marxianus CECT 10875, obtida por mutagenese química da cepa DER-26 de Kluyveromyces marxianus e agitar a mistura durante 72 horas a 42<198>C.
