Provided are acidic thermophilic polygalacturonase TePG28A, encoding gene and application thereof. The amino acid sequence thereof is as shown in SEQ ID NO. 1 or SEQ ID NO. 2. The expressed acidic thermophilic polygalacturonase by means of cloning has advantages such as high enzyme activity and high stability; can adapt to the high temperature environment in the industrial production; has better application prospect; and can effectively degrade pectic substances such as polygalacturonic acid and pectin; and can be effectively applied to the industrial field of feed, food, and textile, etc.

Provided is a method for safely and selectively producing a substrate culture product including a large amount of a desired degrading enzyme. A method for producing a substrate culture product used for feedstuff includes inoculating filamentous fungi bred so that a target degrading enzyme is produced by self-cloning in high productivity on a substrate, and producing the substrate culture product having functionality by ventilating the substrate to carry out solid culture.

The present invention relates to a process for forming a functionalised dietary fibre comprising admixing an enzyme and an aqueous suspension of dietary fibre, wherein said dietary fibre is at a D.sub.50 particle size distribution of less than 30 microns after degradation by the enzyme and comprises less than 25 wt. % soluble fibres and at least 40% wt. % cellulose; denaturing said enzyme to form a functionalised, amphiphilic dietary fibre with adsorbed enzyme. The present invention further relates to a Pickering particle comprising a functionalised dietary fibre and denatured enzyme and the use of the functionalised dietary fibre and denatured enzyme according to present invention or the Pickering particle according to the present invention to stabilize an emulsion.

Provided herein is a hydraulic fracturing fluid containing enzyme encapsulated hydrogel nanoparticles and a breaker composition of a viscosifier-degrading enzyme encapsulated in the hydrogel nanoparticle. Also provided are methods for hydraulic fracturing utilizing hydrogel nanoparticles encapsulating an enzyme as a breaker to prevent the premature degradation of the fracturing fluid, to improve transport and placement of the proppant and to facilitate subsequent cleaning of the fracturing fluid.

The present invention relates to polypeptide variants and methods for obtaining variants. The present invention also relates to polynucleotides encoding the variants; nucleic acid constructs, vectors, and host cells comprising the polynucleotides; and methods of using the variants.

The present invention relates to isolated polypeptides having protease activity, and polynucleotides encoding the polypeptides. 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.

A pretreatment method for producing a raw material of lycopene, comprising: uniformly mixing tomato peel residue with a fermenting agent, an antioxidant and an enzyme preparation, and subjecting the resultant to light-proof anaerobic fermentation. The present invention employs bacteria-enzyme combined fermentation technology, which prolongs the storage period of wet tomato peel residue, and also destroys the cell wall of tomato peels, thus facilitating exaction of lycopene and improving the purity of lycopene extracted in the later stage.
