cultura mista, resíduos lignocelulósicos, etanol 2G, xilitolAbstract
Os resíduos lignocelulosicos produzidos no Brasil podem ser utilizados na produção biomoléculas de maior valor agregado. Desde modo, a fermentação de xilose presente no resíduo é fundamental neste propósito. Um estudo inicial do metabolismo da fermentação aeróbia da mistura d-xilose/d-xilulose pelas cepas S. stipitis e S. cerevisiae foi realizado. Após a fermentação constatou-se a produção de xilitol e etanol no caso da S. stipitis, enquanto que para S. cerevisiae só houve produção de etanol.
