Hidrólise enzimática do amido de mandioca e produção de bioetanol por Saccharomyces cerevisiae CENPK2 expressando uma glicoamilase de Aspergillus awamori
Abstract:This study aimed to verify the hydrolysis of starch raw cassava using a glucoamylase from Aspergillus awamori expressed in Saccharomyces cerevisiae. The glucoamylase activity test plate showed that S. cerevisiae recombinant is able to degrade cassava starch without the needs for either acid pretreatment or cooking. The recombinant yeast was able to form 2.7 g / L of biomass and degrades cassava starch up to 90%, releasing a large amount of glucose to the culture medium. The N-deglycosylation assay showed that … Show more
