Novozymes Novozyme CALB liquid enzyme typically refers to a liquid preparation of lipase B from Candida antarctica. Below is a detailed introduction:

Basic Characteristics

·Source and Production: Produced through fermentation of Candida antarctica, it is manufactured using modern biotechnology by fermenting in hosts such as Pichia pastoris, followed by a series of separation and purification processes to obtain a high-purity liquid enzyme product.

·Appearance and Properties: Generally appears as a yellow to light brown liquid, with color intensity possibly varying between batches. However, color depth does not indicate enzyme activity levels.

Catalytic Performance

·Substrate Specificity: Exhibits high substrate specificity, demonstrating good catalytic activity toward various ester substrates. It can perform ester hydrolysis, transesterification, lactone ring-opening polymerization, aminolysis, hydrolysis and synthesis of amides, and addition reactions across a broad range of substrates.

·Selectivity: Possesses strong chiral and positional selectivity, enabling recognition and action at specific chiral centers or positions. It is used in pharmaceutical synthesis and fine chemicals to produce compounds with high optical purity.

Physicochemical Properties

·pH Stability: Remains stable over a wide pH range, typically exhibiting good activity and stability between pH 5-9, allowing adaptation to various acid-base environments in different reaction systems.

·Temperature Stability: The recommended reaction temperature is generally between 30-60°C. Within this range, it maintains high catalytic efficiency while helping reduce energy consumption costs in industrial production.

Application Areas

·Food Industry: Used for fat modification, such as in the hydrolysis and transesterification of oils and fats to improve their physicochemical properties and nutritional value. In dairy production, it facilitates fat hydrolysis and the generation of flavor compounds, enhancing product taste and quality.

·Fine Chemicals: In the synthesis of cosmetic ingredients, it catalyzes the synthesis of ester compounds for producing fragrances, flavors, and emulsifiers. In surfactant synthesis, it enables efficient transesterification reactions to produce surfactants with specific properties.

·Pharmaceutical Industry: Used in the synthesis of pharmaceutical intermediates for preparing chiral drug intermediates. Its high selectivity catalyzes specific reactions, improving the optical purity and efficacy of drugs. In drug formulation production, it helps enhance drug solubility and stability.

Advantages

·High Efficiency: Exhibits high catalytic efficiency, achieving high substrate conversion rates in relatively short timeframes, thereby improving production efficiency.

·Mild Reaction Conditions: Catalytic reactions typically occur under mild temperature and pH conditions, reducing the need for high temperatures and pressures. This lowers energy consumption and equipment requirements during production while minimizing side reactions.

·Environmentally Friendly: As a biocatalyst, it is biodegradable and does not cause long-term environmental pollution after use, aligning with the trends of green chemistry.
