Abstract

a presente invenção se refere a um processo de conversão que fornece o uso de diferentes linhagens celulares cocultivadas para expressar diferentes conjuntos de enzimas que catalisam o mesmo processo. por exemplo, em um processo de sacarificação e cofermentação simultâneas (sscf), um substrato de amido é convertido em álcool pela colocação do substrato em contato com células de levedura e de aspergillus niger. devido ao fato de que a. niger expressa uma glicoamilase endógena e uma alfa-amilase endógena, estas enzimas não precisam ser adicionadas durante o processo de sscf.
