摘要:
The present disclosure relates to the production of highly efficient heterologous pathways in host cells by identifying favorable enzyme and/or promoter combinations. In particular the present disclosure provides methods for assembly and selection of multi-step xylose and arabinose/xylose utilization pathways from a library of fungal enzymes. The present disclosure further provides compositions containing favorable enzyme combinations, as well as recombinant yeast expressing such combinations, and methods of use for bioconversion of pentose sugars. Also provided are compositions and methods involving favorable expression patterns identified by utilization of combinations of promoters of varying strengths. Provided herein are methods for assembly and selection of multi-step xylose, arabinose/xylose, and cellobiose utilization pathways from a library of promoters of varying strengths. The present disclosure further provides compositions containing heterologous enzyme-coding polynucleotides under the control of favorable promoters, as well as recombinant yeast expressing such enzymes, and methods of their use for bioconversion of pentose and/or hexose sugars.

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.
