10. Phosphorus and the animal diet • Phosphorus vitally important for bone and tissue growth • Phosphorus (organic) stored in phytate and found in corn and soybean oil – animal feeds • Phytic acid not readily digestible by monogastric animals • Must add supplementary mineral phosphorus • Expensive, replaces other valuable nutrients,increases phosphorus in waste, causes pollution.

11. Phytate (myo-inositol hexaphosphate) is the principal storage form of phosphorus in plant seeds Considered an anti-nutrient -Chelates essential dietary minerals such as calcium, iron, copper, and zinc Phosphorus in phytate is nutritionally unavailable to monogastric animals To provide adequate dietary phosphorus to animals, inorganic phosphates are added to formulated animal feeds Phytate

12. 80+ million tons inorganic Phos @ $1-2/ton 600 000 metric tons of Phos waste = Environmental Cost Adding Phosphate to Feed Costs $ and Causes Pollution Many countries are beginning to regulate animal production based upon amounts of Phos in animal waste

13. Phytase H OH H OH H OH H OH H OH H OH Inositol Phytate 6 PO4 • An enzyme that removes Phos from phytate • Used widely in the feed of monogastric animals to allow animals to utilize the Phos contained naturally in feed components (corn, wheat, soy) • Use allows reduction of inorganic forms of Phos in feed • Reduces Phos in animal waste – positive environmental impact

14. Current Phytase Market • Most widely accepted feed enzyme; recognized efficacy • Increases animal performance on low Phos diets; reduces need for inorganic Phos • Fastest growing segment of feed enzyme market • Limitations in price/performance of current products will cap ultimate market penetration and growth • >$120M globally with the potential to grow to >$350M

15. Limitations of conventional phytases Animal feed is commonly formed into pellets, a manufacturing process that requires moisture and heat. Most phytases are unstable under normal temperature pelleting conditions and must be applied either with a protective coating before pelleting or post-pelleting by liquid application. Can result in sub-optimal feed and inconsistent animal performance.

16. Steam (90° C) Phytase Why Thermotolerance? Feed Ingredients Pellet Formation Cool Mixing High Capital Cost
