Yeast expressing saccharolytic enzymes for consolidated bioprocessing using starch and cellulose

The present invention is directed to a yeast strain, or strains, secreting a full suite, or any subset of that full suite, of enzymes to hydrolyze corn starch, corn fiber, lignocellulose, (including enzymes that hydrolyze linkages in cellulose, hemicellulose, and between lignin and carbohydrates) and to utilize pentose sugars (xylose and arabinose). The invention is also directed to the set of proteins that are well expressed in yeast for each category of enzymatic activity. The resulting strain, or strains can be used to hydrolyze starch and cellulose simultaneously. The resulting strain, or strains can be also metabolically engineered to produce less glycerol and uptake acetate. The resulting strain, or strains can also be used to produce ethanol from granular starch without liquefaction. The resulting strain, or strains, can be further used to reduce the amount of external enzyme needed to hydrolyze a biomass feedstock during an Simultaneous Saccharification and Fermentation (SSF) process, or to increase the yield of ethanol during SSF at current saccharolytic enzyme loadings. In addition, multiple enzymes of the present invention can be co-expressed in cells of the invention to provide synergistic digestive action on biomass feedstock. In some aspects, host cells expressing different heterologous saccharolytic enzymes can also be co-cultured together and used to produce ethanol from biomass feedstock.

RECOMBINANT YEAST HOST CELL EXPRESSING AN HYDROLASE
20210348145 · 2021-11-11 ·

The present disclosure concerns a recombinant yeast host cell exhibiting higher stability and, in some embodiments, higher fermentation performance. The recombinant yeast host cell stability has a limited ability to express an hydrolase during its propagation phase. In return, this limits the cleavage of a yeast cellular component during or after propagation which may be detrimental to the stability and/or fermentation performances. The recombinant yeast host cell expresses a heterologous hydrolase under the control of a heterologous promoter (for limiting the expression of the heterologous hydrolase during propagation and favoring the expression of the heterologous hydrolase during fermentation).

Mutant of alpha-N-Acetylglucosaminidase

The present invention relates to a mutant of human α-N-acetylglucosaminidase (hNAGLU), more specifically a hNAGLU mutant produced by adding a mutation to an amino acid sequence for hNAGLU such that an expression level of hNAGLU in a host cell in which a gene encoding hNAGLU is introduced can be increased compared with the case where a gene encoding wild-type hNAGLU is introduced. For example, the hNAGLU mutant has an amino acid sequence represented by SEQ ID NO: 3, SEQ ID NO: 5, SEQ ID NO: 9, SEQ ID NO: 11, SEQ ID NO: 15, or SEQ ID NO: 19, or has an amino acid sequence introduced a mutation to the amino acid sequence of any one of the hNAGLU mutants.

VARIANTS OF A FAMILY 44 XYLOGLUCANASE

The present disclosure relates to xyloglucanase variants. The present invention also relates to polynucleotides encoding the variants; nucleic acid constructs, vectors, and host cells comprising the polynucleotides; and methods of using the variants.
