A hangover relieving composition including a dry powder, lysate or extract of yeast that produces glutathione and acetaldehyde dehydrogenase. Further, embodiments relate to a hangover relieving composition containing the dry powder, lysate or extract of Saccharomyces cerevisiae Kwon P-1 KCTC13925BP and Saccharomyces cerevisiae Kwon P-2 KCTC14122BP and Saccharomyces cerevisiae Kwon P-3 KCTC14123BP yeast that simultaneously produce glutathione and acetaldehyde dehydrogenase.

The present disclosure provides recombinant microorganisms and methods for the anaerobic production of 2,4-furandimethanol from one or more carbon sources. The microorganisms and methods provide redox-balanced and ATP positive pathways for co-producing 2,4-furandimethanol with ethanol and for co-producing 2,4-furandimethanol with ethanol and acetone and/or isopropanol. The method provides recombinant microorganisms that express endogenous and/or exogenous nucleic acid molecules encoding polypeptides that catalyze the conversion of a carbon source into 2,4-furandimethanol and that couple the 2,4-furandimethanol pathway with an additional metabolic pathway. The present disclosure further provides enzymatic production of 2,4-furandicarboxylic acid.

The invention provides an improved host strain for production of desired protein.

Described are compositions and methods relating to modified yeast that over-express MIG transcriptional regulator polypeptides. The yeast produces a deceased amount of acetate compared to parental cells. Such yeast is particularly useful for large-scale ethanol production from starch substrates where acetate in an undesirable end product.

Described herein are recombinant host organisms expressing a sugar transporter and an active pentose fermentation pathway. Also described are processes for producing a fermentation product, such as ethanol, from starch or cellulosic-containing material with the recombinant host organisms.

The disclosed subject matter provides for genetically modified cells, e.g., fungal cells, that autonomously generates and/or secretes one or more therapeutic molecules, e.g., therapeutic peptides, therapeutic proteins or small therapeutic molecules, in situ. In certain embodiments, the present disclosure provides genetically-engineered fungal cells that generate and secrete tetracycline and analogues thereof.

The present disclosure provides yeasts, which can be recombinant yeast host cells, exhibiting prolonged persistence when submitted to a plurality of fermentation cycles. The yeasts exhibit at least one of the following phenotypic trait: a fast settling phenotype, a rugose phenotype, an improved invertase activity, triploidy, increased signaling in a RAS/cAMP/PKA pathway or combinations thereof.

The present invention relates to isolated polypeptides having beta-glucanase activity, catalytic domains, carbohydrate binding modules and polynucleotides encoding the polypeptides, catalytic domains or carbohydrate binding modules. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the polynucleotides as well as methods of producing and using the polypeptides, catalytic domains or carbohydrate binding modules. The present invention further relates to processes for producing fermentation products from starch-containing or cellulosic-containing material, as well as an enzyme blend or composition, or a recombinant host cell or fermenting organism suitable for use in processes of the invention.

The present disclosure is related to the fields of biology, molecular biology, genetics, microbial fermentation, alcohol production and the like. The present compositions and methods relate to yeast strains comprising genetic modifications that results in modified yeast strains thereof comprising enhanced stress tolerance. Certain embodiments of the disclosure are therefore related to compositions and methods for increasing the efficiency of alcohol production using such modified yeast strains in fermentation reactions/processes.

Embodiments provide a modified microbe capable of growing in or fermenting a solution, or lignocellulosic hydrolysate, comprising ferulic acid and/or coniferyl aldehyde. The microbe has one or more modifications to provide: (a) a decrease in copy number or expression of a BNA7 gene; (b) an increase in copy number or expression of one or more pentose phosphate pathway genes; and/or (c) localization of one or more products of the pentose phosphate pathway genes to the mitochondria or endoplasmic reticulum. Also provided is a microbe having modified expression or copy number of BNA7 and/or one or more of the pentose phosphate pathway genes. The pentose phosphate pathway genes may in certain embodiments be selected from at least one of ZWF1, TKL1, RPE1 and GND1. Also provided is a method for fermenting a substrate comprising ferulic acid and/or coniferyl aldehyde to produce a fermentation product.
