The Application of Protease and Other Enzymes in Aquaculture
Different Types of Protease
The Application of Protease and Other Enzymes in Aquaculture is mainly reflected in the following aspects:
Promote digestion and nutrient absorption: Many Enzymes like that of Protease can break down protein in feed into small molecule peptides or free amino acids, thereby increasing the bioavailability of protein and helping aquatic animals digest and absorb nutrients more effectively. For example, adding Protease and other Enzymes to the feed of shrimp and fish can improve protein digestion and absorption, promoting growth and development.
Reduce environmental pollution: Enzymes such as Protease can decompose organic matter, reduce the accumulation of waste in aquaculture, improve water quality, and reduce the impact of water waste on the health of aquatic animals, thereby reducing the occurrence of diseases.
Enhance resistance: Certain Enzymes such as Protease and glucanase can stimulate the immune system of aquatic animals, improve their resistance, and help resist bacterial and viral invasion. Therefore, adding Enzymes to the diet of aquatic animals is proven to increase overall immunity.
Reduce production costs: Through "automatic enzymatic hydrolysis" technology, Enzymes like Protease can be directly used in the feed production process, avoiding processes such as drying, packaging, and transportation, and reducing production costs. This technology achieves synchronous enzymatic hydrolysis of raw materials such as Enzymes and feed processing by installing an online enzymatic reactor, solving problems such as adhesion of high viscosity materials after the hydrolysis of Enzymes, difficulty in discharging from the warehouse, and contamination of pipelines.
Types of Enzymes and Their Mechanisms of Action in Aquaculture:
Protease: Enzymes responsible for breaking down proteins into amino acids, improving protein digestion and absorption.
Starch amylase: Enzymes capable of breaking down starch into monosaccharides, providing rapid energy for aquatic animals.
Cellulase: Enzymes that break down cellulose and improves the digestion of plant-based feed.
Future research directions:
Future research needs to focus on how to efficiently apply Enzymes such as Protease to aquaculture while ensuring their biological activity. This includes addressing the issue of Protease deactivation during high-temperature feed processing, as well as further optimizing the "auto-enzymatic hydrolysis" technology to break down Enzymes will help to achieve more efficient and environmentally friendly production methods. In the ever-so developing industry of aquaculture, various feed additives such as probiotics like Bacillus spp. and Enzymes such as Protease, Cellulase, Glucanase, Xylanase, Mannanase, and Amylase are being used to promote nutritional health through digestion, enhance resistance to disease by strenghtening overall immunity, and reduce production costs while still being environmentally friendly. The industry of Enzymes itself is growing, and while it can be useful in so many industries, it is an important factor in that of aquaculture.
