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.

In some embodiments, the present invention provides a recombinant protein comprising an affinity tag configured to attach the recombinant protein to a silicate surface, fused to a hydrogen sulfide scavenging enzyme.

The present invention relates to a CHO cell-derived protein secretory factor, an expression cassette in which a nucleic acid sequence encoding the protein secretory factor; and a gene encoding a target protein are operably linked, an expression vector comprising the expression cassette, a transformed cell into which the expression vector is introduced, and a method for producing a target protein using the transformed cell.

This disclosure provides an E. coli strain, which lacks thioredoxin reductase activity encoded by trxB and thioredoxin 1 activity encoded by trxA, and glutathione reductase activity encoded by gor. Said E. coli strain expresses a mutated AhpC protein having glutathione reductase activity and a cytosolic prokaryotic disulfide isomerase. The E. coli strain has an oxidative cytosol and can be used to efficiently produce proteins having disulfide bonds.

The present disclosure identifies pathways, mechanisms, systems and methods to confer chemoautotrophic production of carbon-based products of interest, such as sugars, alcohols, chemicals, amino acids, polymers, fatty acids and their derivatives, hydrocarbons, isoprenoids, and intermediates thereof, in organisms such that these organisms efficiently convert inorganic carbon to organic carbon-based products of interest using inorganic energy, such as formate, and in particular the use of organisms for the commercial production of various carbon-based products of interest.

Compositions comprising an engineered or non-naturally occurring polypeptides comprising two or more domains selected from Sulfide quinone oxidoreductase, Thiosulfate Sulfurtransferase and persulfide dioxygenase, and a phosphate binding motif are provided along with methods of detoxifying bacterial endotoxins and H.sub.2S with such compositions.

Disclosed are a thioredoxin mutant, preparation method thereof, and application thereof in production of recombinant fusion protein. The recombinant fusion protein produced by the expression of the thioredoxin mutant of the present invention has good solubility and stability in high-temperature environments and is not easily denatured.

Modified bacterial strains are provided. The strains can generate a desired product such as pyruvate and products derived from pyruvate. Methods of generating pyruvate and products derived from pyruvate are also provided. The modified bacterial strains have at least one mutation in a gene coding for proteins in a pyruvate dehydrogenase complex such that the mutation allows a cell to accumulate pyruvate and/or products derived from pyruvate.

A method and a mineral wool product include a multiple of lamellae, such as a sandwich panel core. The product includes a plurality of lamellae cut from a mineral wool web, and bonded together by applying an adhesive on the surfaces of two adjacent lamellae to form a web-like product, wherein the adhesive comprises at least one hydrocolloid.

The present invention relates to a genetically engineered microorganism expressing (i) formate tetrahydrofolate (THF) ligase, methenyi-THF cyclohydrolase and methylene-THF dehydrogenase, (ii) the enzymes of the glycine cleavage system (GCS), (iii) serine deaminase and serine hydroxymethyltransferase (SHMT), (iv) an enzyme increasing the availability of NADPH, and (v) optionally formate dehydrogenase (FDH), and wherein the genetically engineered microorganism has been genetically engineered to express at least one of the enzymes of (i) to (v), wheren said enzyme is not expressed by the corresponding microorganism that has been used to prepare the genetically engineered microorganism, and wherein the enzymes of (i) to (v) are genomically expressed.
