Abstract

"CéLULA HOSPEDEIRA RECOMBINANTE, MéTODOS PARA ENZIMATICAMENTE DEGRADAR UM OLIGOSSACARìDEO, PARA IDENTIFICAR UM PROMOTOR SUBSTITUTO CAPAZ DE AUMENTAR A EXPRESSãO DE UM GENE-DE-INTERESSE EM UMA CéLULA HOSPEDEIRA, PARA PRODUZIR UMA CéLULA HOSPEDEIRA RECOMBINANTE PARA USO EM SIMULTâNEAS SACARIFICAçãO E FERMENTAçãO, PARA PRODUZIR UMA CéLULA HOSPEDEIRA RECOMBINANTE INTEGRANTE, PARA EXPRESSAR UMA POLISSACARASE EM UMA CéLULA HOSPEDEIRA E PARA PRODUZIR ETANOL DE UMA FONTE DE OLIGOSSACARìDEO, E, VETOR". A invenção provê células hospedeiras recombinantes, contendo pelo menos um polinucleotídeo heterólogo codificando uma polissacarase sob o controle transcricional de um promotor substituto, capaz de aumentar a expressão da polissacarase. Além disso, a invenção fornece ainda tais hospedeiros com genes codificando proteína(s) secretória(s), para facilitar a secreção da polissacarase expressa. Os hospedeiros preferidos da invenção são etanologênicos e capazes de realizar simultâneas sacarificação e fermentação, resultando na produção de etanol de substratos de celulose complexos.
