The invention relates to a gene construct comprising at least two nucleic acid sequences, wherein one of the nucleic acid sequences encodes FAH and a second nucleic acid sequence encodes a protein to be produced. This makes it possible to use FAH as a selection marker for the production of recombinant proteins, in particular antibodies. The invention further relates to plasmids, vectors or hepatocytes comprising the gene construct. Furthermore, the invention relates to a method for producing recombinant proteins in FAH(−/−) non-human mammals using the gene construct and FAH as a selection marker.

Genetically modified plants and methods of detecting diseases by a relevant color change in the genetically modified plant compared to a non-genetically modified plant are provided. Also disclosed is a system for remote detection of pathogens on crops and a methods for treating crops under a pathogenic attack.

The present disclosure relates to a microorganism expressing active D-proline reductase.

Certain embodiments provide a method for preparing a biochemical product (e.g., phenol, catechol, or muconic acid, or a salt thereof). For example, such methods include contacting a recombinant host having two or more recombinant pathways with a fermentable carbon source and growing the recombinant cell for a time sufficient to synthesize the product. In certain embodiments, each recombinant pathway: 1) is capable of producing the same final biochemical product; 2) comprises at least one gene encoding a polypeptide; 3) is derived from a different endogenous metabolite as its immediate precursor; and 4) converges to the same final product or the same intermediate metabolite.

The present invention relates to Actinomycetales strains for the improved formation of acarbose. Provided are Actinomycetales strains which are engineered to overexpress dTDP-D-glucose-4,6-dehydratase (AcbB) and/or uridyltransferase (GtaB). Also provided are Actinomycetales strains which are engineered to have a reduced or absent expression of the small carbohydrate binding protein (Cgt) and/or a reduced or absent expression of genes which are essential for carotenoid synthesis. Also provided are tools, methods and means to generate these strains.

The present invention provides a resin capable of contributing greatly to solve environmental problems and problems related to exhaustion of fossil fuel resources and having physical properties suited for practical use. The polyester according to the present invention has a diol and a dicarboxylic acid as constituent components and has an amount of terminal acid of 50 equivalents/metric ton or less.

Non-naturally occurring microorganisms are provided that produce C40 carotenoid compound(s), utilizing exogenously added enzyme activities. Methods of producing C40 carotenoid compounds in microbial cultures, and feed and nutritional supplement compositions that include the C40 carotenoid compounds produced in the microbial cultures, are also provided.

This disclosure relates to genetically engineered microorganisms for treating or reducing the risk of bacterial infections or dysbiosis, and further discloses methods of making and using such microorganisms.

Surfactants based on a newly discovered class of compounds include a hydrophobic lipid oligomer covalently linked to a peptide or peptide-like chain and a carbohydrate moiety, and a serine-leucinol dipeptide linked to the lipid oligomer. Such surfactants can be used to create an oil-in-water or water-in-oil emulsion by mixing together a polar component; a non-polar component; and the surfactant. Biosurfactants of the newly discovered class can be made by isolating and culturing a microorganism which produces the biosurfactant, and then isolating the biosurfactant from the culture. A microorganism can be engineered to produce biosurfactant of this newly discovered class by expressing a set of heterologous genes involved in the biosynthesis of the biosurfactant in the microorganism.
