摘要:
A genetically modified microorganism containing a gene capable of expressing a mutated YeeX protein or a homolog thereof, which results from substitution, insertion, and/or deletion of one to several amino acids in the amino acid sequence of the wild-type YeeX protein or of a homolog thereof, has a higher capacity to produce an organic acid(s) than the genetically unmodified original microorganism.
摘要:
A pesticidal protein class of PirA, PirB, and PirAB fusion proteins exhibiting toxic activity against Coleopteran, Lepidopteran, and Hemipteran pest species is disclosed. DNA constructs are provided which contain a recombinant nucleic acid sequence encoding the PirA, PirB, and PirAB fusion proteins. Transgenic plants, plant cells, seed, and plant parts resistant to Coleopteran, Lepidopteran, and Hemipteran infestation are provided which contain recombinant nucleic acid sequences encoding the PirA, PirB, and PirAB fusion proteins. Methods for detecting the presence of the recombinant nucleic acid sequences or the proteins of the present invention in a biological sample, and methods of controlling Coleopteran, Lepidopteran, and Hemipteran species pests using the PirA, PirB, and PirAB fusion proteins are also provided.
摘要:
The present invention relates to the field of recombinant production of biological molecules in genetically modified cells. More particularly, it relates to a method for recombinant production of sialylated human milk oligosaccharides (HMO) using a genetically modified cell expressing a protein of the major facilitator superfamily (MFS), the protein expressed being Fred.
摘要:
The present invention relates to probiotic compositions. More specifically, the present invention relates to probiotic compositions that are useful in reducing inflammation and/or that exhibit increased colonization or persistence in the gastrointestinal tract of a mammal.
摘要:
Provided are a gene combination used for controlling foreign gene expression in a specific plant tissue, and a method applying the gene combination to cultivate a transgenic plant. The method is used to cultivate, for example, an endosperm zero expression-type transgenic rice, i.e., rice grain endosperm produced by the rice does not contain any transgenic product protein synthesis and accumulation.
摘要:
The present invention provides isolated polypeptides isolatable from a Yersinia spp. Also provided by the present invention are compositions that include one or more of the polypeptides, and methods for making and methods for using the polypeptides.
摘要:
Compositions and methods for controlling pests are provided. The methods involve transforming organisms with a nucleic acid sequence encoding an insecticidal protein. In particular, the nucleic acid sequences are useful for preparing plants and microorganisms that possess insecticidal activity. Thus, transformed bacteria, plants, plant cells, plant tissues and seeds are provided. Compositions are insecticidal nucleic acids and proteins of bacterial species. The sequences find use in the construction of expression vectors for subsequent transformation into organisms of interest, as probes for the isolation of other homologous (or partially homologous) genes. The insecticidal proteins find use in controlling, inhibiting growth or killing lepidopteran, coleopteran, dipteran, fungal, hemipteran, and nematode pest populations and for producing compositions with insecticidal activity.
摘要:
The present application is related to a recombinant microorganism optimised for the fermentative production of methionine and/or its derivatives, wherein in said recombinant microorganism, the cobalamin-dependent methionine synthase activity and the methionine efflux are enhanced. The application is also related to a method for optimizing the fermentative production of methionine and/or its derivatives comprising the steps of: c. culturing a recombinant microorganism wherein in said microorganism, the cobalamin-dependent methionine synthase activity and the methionine efflux are enhanced, in an appropriate culture medium comprising a fermentable source of carbon and a source of sulphur, and d. recovering methionine and/or its derivatives from the culture medium.
