Abstract: The current invention discloses enzyme-based compositions for converting raw natural fibres from plant derived biomass into high quality textile grade fibres. The invention discloses at least one multi-component enzymatic formulation, and the optimal conditions for using these enzymatic formulations, which result in production of textile grade fibres from raw natural fibres. These textile grade fibres can be used in any industry, because of their high-quality parameters, and high spinnability index.

Abstract: The purpose of the present invention is to provide a novel feature by which the strength of tofu can be increased with a method for producing tofu using an enzyme. Tofu obtained by a tofu production method that includes a crosslinking step in which laccase is acted on soy milk exhibits increased strength, and when the tofu production method thereof further includes a boiling step after the crosslinking step, the strength of the obtained tofu is dramatically improved.

Abstract: The present invention provides a novel method for improving microbial laccase production, which relates to the field of microbial fermentation. The present invention is to add β-carotene and other types of carotenoids, or microorganisms that produce carotenoids, or mixtures comprising carotenoids into a fermentation system during fermentation of Pleurotus ferulae and other higher fungi. The present invention can improve the laccase production 12 times more than before, with the advantages of a simple process and high yield.

Abstract: Aspects of the present disclosure are drawn to methods of improving the expression of secreted cuproenzymes from host cells by manipulating the expression level of one or more proteins involved in copper transport in the host cell, e.g., membrane-bound copper transporting ATPases and soluble copper transporters. The present disclosure also provides compositions containing such improved host cells as well as products derived from the improved host cells that contain one or more cuproenzymes of interest.

Abstract: A method for depolymerization of lignin includes oxidizing non-phenolic lignin by putting into presence, in at least one solvent, non-phenolic lignin, laccase, redox mediator and a source of oxygen, whereby a mixture including oxidized non-phenolic lignin is obtained, and further includes depolymerization of the oxidized non-phenolic lignin thereby obtained, by adding an oxidizer. The non-phenolic lignin is obtained from phenolic lignin by functionalization of phenol functions of the phenolic lignin.
