Why Is the GH10 Family of Xylanases More Effective?
Substrate Specificity: GH10 xylanases tend to exhibit a broader substrate specificity compared to GH11 xylanases. They can efficiently hydrolyze a wider range of xylan structures found in various plant cell walls. This broader specificity allows for better degradation of different types of dietary fiber present in animal feed ingredients.
Enhanced Thermal Stability: GH10 xylanases often demonstrate better heat resistance, which is crucial in the feed manufacturing process. The ability to withstand higher temperatures during feed processing, such as pelleting or extrusion, ensures that the enzyme remains active and effective throughout the entire production cycle.
Improved pH Tolerance: GH10 xylanases may have better pH tolerance, allowing them to function optimally in the diverse pH conditions of the digestive tract. This can lead to improved enzyme activity and greater efficiency in breaking down xylan in the animal's gastrointestinal system.
Higher Catalytic Efficiency: GH10 xylanases are known for their higher catalytic efficiency, meaning they can break down xylan molecules more rapidly and effectively. This leads to better utilization of nutrients in the feed, improved feed conversion, and enhanced animal performance.
Resistance to Protease Inhibition: In some cases, GH11 xylanases may be inhibited by the presence of proteases or other enzymes in the digestive system. GH10 xylanases are often more resistant to such inhibitory effects, ensuring their continued activity in the gut.
Broader Application Range: Due to their versatility and improved performance under various conditions, GH10 xylanases are better suited for a wide range of feed formulations and animal species, making them a more flexible choice for commercial nutritionists.
Recent innovations in enzyme technology have further improved the effectiveness of xylanase and other enzymes in animal nutrition. Customized enzyme solutions, heat-stable xylanases, enzyme combinations, molecular genetics, and nutrigenomics are all contributing to the advancement of precision nutrition in animal production. As these innovations continue to evolve, they hold the promise of further optimizing animal performance and sustainability in the livestock and poultry industries.
