Abstract

The present disclosure relates to host cells containing a recombinant polynucleotide encoding a polypeptide where the polypeptide transports cellodextrin into the cell. The present disclosure further relates to methods of increasing transport of cellodextrin into a cell, methods of increasing growth of a cell on a medium containing cellodextrin, methods of co-fermenting cellulose-derived and hemicellulose-derived sugars, and methods of making hydrocarbons or hydrocarbon derivatives by providing a host cell containing a recombinant polynucleotide encoding a polypeptide where the polypeptide transports cellodextrin into the cell. The present disclosure relates to host cells containing a recombinant polynucleotide encoding a polypeptide where the polypeptide transports a pentose into the cell, methods of increasing transport of a pentose into a cell, methods of increasing growth of a cell on a medium containing pentose sugars, and methods of making hydrocarbons or hydrocarbon derivatives by providing a host cell containing a recombinant polynucleotide encoding a polypeptide where the polypeptide transports a pentose into the cell.
