Methods of utilizing xylose as a carbon source using secretory expression of xylose isomerase

摘要

The present invention relates to a recombinant fusion partner (TFP) comprising a polynucleotide encoding a protein fusion partner (TFP) and a polynucleotide encoding a xylose isomerase, a secretory expression for secretion of xylose isomerase in the yeast Expression cassette, an expression vector comprising the expression cassette, and a transformant microorganism into which the expression vector has been introduced. The present invention also relates to a method for producing xylose isomerase comprising the step of culturing the transformed microorganism and a method for producing gylulose, which comprises culturing the transformed microorganism in a medium containing xylose as a carbon source /RTI By using xylose as a carbon source using a cassette, a vector, and a transforming microorganism expressing the xylose isomerase of the present invention, it is possible to secure economical efficiency of bioethanol produced from the fibrous biomass have.;
