There are several types of phytase, classified based on their source and optimal pH range. The most common are:
Microbial Phytase: Derived from fungi and bacteria, these phytases are widely used in the animal feed industry due to their robustness and high activity levels. Plant Phytase: Found naturally in seeds and grains, these phytases are less commonly used due to their lower activity compared to microbial phytases. Probiotic Phytase: Produced by certain probiotics, these phytases contribute to improved gut health and nutrient absorption in animals.
