Description

Laccase is a versatile multi-copper oxidase enzyme that catalyzes the oxidation of a wide range of phenolic and non-phenolic substrates, with the concomitant reduction of molecular oxygen to water. This biocatalyst is valued for its ability to degrade complex polymers like lignin, making it a key tool in green industrial processes. It is essential for manufacturers and researchers in the textile, pulp & paper, food & beverage, and bioremediation sectors seeking efficient, environmentally friendly enzymatic solutions.

Application

• Textile Processing: Used for bio-bleaching of denim (stone-washing effect) and decolorization of textile dye effluents.
• Pulp & Paper Industry: Employed in bio-bleaching of wood pulp to reduce the use of harsh chlorine-based chemicals and in delignification processes.
• Food & Beverage: Applied in juice and wine clarification, baking (dough conditioning), and as a processing aid for stabilization.
• Bioremediation & Waste Treatment: Degrades phenolic pollutants, endocrine disruptors, and dyes in industrial wastewater.
• Biofuel Production: Aids in the pretreatment of lignocellulosic biomass by breaking down lignin to improve sugar yield for fermentation.
• Biosensors & Diagnostic Kits: Serves as an enzymatic component in electrochemical sensors for detecting phenols, catechols, and other analytes.
• Cosmetics & Personal Care: Explored for hair dyeing formulations and as an active ingredient in skin care products for its antioxidant properties.
• Organic Synthesis: Acts as a green catalyst for the synthesis of complex organic molecules and polymers.

Quality Control

Our Laccase is produced and tested under a stringent quality management system to ensure batch-to-batch consistency and performance. Each lot is characterized for key enzymatic parameters including activity, purity, and stability. A comprehensive Certificate of Analysis (COA) detailing assay results, specific activity (U/mg), pH optimum, temperature stability, and absence of specified microbial contaminants is provided with every shipment. Production can adhere to relevant standards for industrial or research grades.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store lyophilized (freeze-dried) powder at 2-8°C. Solutions or liquid formulations should be stored at recommended temperatures, typically 2-8°C, and are sensitive to freezing. The product is hygroscopic (moisture-sensitive).
