Abstract
PROCESSO DE SìNTESE DE éSTERES COM LIPASES IMOBILIZADAS NO SUBSTRATO SóLIDO FERMENTADO. A presente invenção refere-se a um processo de síntese de ésteres através de reações de esterificação, transesterificação (alcoólise e acidólise) e interesterificação catalisado por lipases. O objetivo da invenção é viabilizar a utilização de lipases para a produção de ésteres, visto que o custo de obtenção de lipases ainda é alto. Neste processo as lipases são produzidas por fermentação no estado sólido (FES) e o substrato fermentado obtido (contendo a enzima e o microrganismo) é adicionado diretamente ao meio reacional para catálise da reação, eliminando as etapas de extração, purificação e imobilização da lipase. Além disso, o custo de produção ainda é reduzido através da utilização de resíduos agro-industriais como substratos. Obtém-se, portanto, uma lipase imobilizada no próprio substrato e que pode ser reutilizada por diversas vezes.
