Described herein is a PAH-degrading enzyme mixture obtained from a culture of PAH-utilizing microorganisms having been grown in presence of one or more enzyme inducers. Related methods and devices are also described.

A method for conferring tolerance to a 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor herbicide in a plant by expressing one or more polypeptide components of an exogenous plastoquinone-9 pathway in the plant. Nucleic acids, vectors, transgenic cells and transgenic plants useful in such a method are also disclosed.

Herbicide-detoxifying enzymes, compositions containing one or more of the enzymes, and plant seeds treated with the enzymes are provided. The enzymes can be used in methods for detoxifying auxin herbicides or degrading auxin plant regulators, including in methods for decontaminating surface of an apparatus used in agriculture or pesticide manufacturing, methods for decontaminating water, soil, soilless media, or sludge, and methods for protecting a plant from an auxin herbicide, improving a plant's tolerance to an auxin herbicide, or removing an auxin herbicide from the surface of a plant.

The present invention provides a method for producing an aromatic compound such as salicylic acid and a derivative thereof with high productivity using a microorganism. The present invention provides: a method for producing a microorganism having a sugar metabolic pathway modified, including suppressing the expression of a gene encoding a phosphotransferase system enzyme of the microorganism, suppressing the expression of a gene encoding pyruvate kinase of the microorganism, and introducing, into the microorganism, one or more genes encoding an enzyme that enables the microorganism to synthesize an aromatic compound from chorismic acid or isochorismic acid; a modified microorganism obtained by the method; and a method for producing an aromatic compound and a derivative thereof, including culturing the microorganism, and recovering an aromatic compound or the like from the culture.

The invention provides a recombinant microorganism that has been genetically engineered to contain metabolic pathway for the production of muconic acid from a salicylic acid intermediate. The genetically engineered metabolic pathway comprises both biosynthetic and biodegradative elements.
