TRIAL PROCESSING OF DIGESTIVE ENZYME PRODUCT OF PHYTASE FROM TRICHODERMA ASPERELLUM ON THE PILOT SCALE

Abstract

Phosphor is mineral component that has a great effect to the growth of livestock. The raw materials for pellet feed contains a high content of organic phosphor. While, the livestock mainly absorb inorganic phosphor in feed. Adding phytase products to the ration of livestock will help them effectively use this mineral amount. The results show that Trichoderma asperellum strain biosynthesis phytase with the highest effectivity at 4 day culture. The most suitable temperature for drying the product was 55^oC with the phytase activity got 4.45UI/g. This activity maintained at least for 12 months at 5^oC and for 6 months at the room temperature. The trial processing was carried out at the scale of 22.5kg/batch be corresponding to one ton every month. A good absorption of organic phosphor in feed is not only helps improve the breeding productivity but also reduces the danger of polluted environment from the animal waste.
