1.Improve metabolic energy utilization rate of meal like raw material soybean meal, cottonseed meal, rapeseed meal, reduce chyme viscosity, improve animal production performance and increase feed/gain ratio. 
2. Completely degrade oligosaccharide of meal like raw materials, reduce nutrients residue in chyme, and increase nutrient utilization rate.
3. Eliminate flatulence, diarrhea of mono-gastric animals, deal to digestive disorders caused by oligosaccharide.
4. Ease or avoid alimentary apparatus compensatory hyperplasia, reduce animal maintenance requirements, improve feed energy valence.
5,Neutral protease can be applied in hydrolyzing the protein molecule to polypeptide or amino acid , forming the protein with unique flavor and hydrolyze the liquid.
6,Neutral protease  can be used in ordinary detergents and industry washing, Neutral protease  can help to remove stains formed by blood , eggs , juice, dairy products or gravy etc effectively. This Neutral protease  also used as medical reagent enzyme to wash the biochemical instrument.

1.Food grade neutral enzyme:
(1).Neutral enzyme can apply on animal protein hydrolysis with high AN%, high degree of hydrolysis and special flavor. It can also be used to produce HAP and HVP for high grade flavoring and food enhancer.Hydrolysis condition:50-55ºC, PH 6.0-7.0, 0.3-1%
adding according to total meat.
( 2).Baking industry's application, can be used to produce high, middle and low grade biscuit with nice plasticity and extensibility. Keep clear shapely print pattern. Improve the product appearance etc.
Application condition:30-60ºC,most suitable temperature 42ºC, PH5.5-7.0,adding weight is 10-15g per 100kg flour.
2.Pharmaceutical industry: 1398 proteasehave strong ability to decompose mucopolysaccharide and get rid ofsputum, suitable to treat chronic bronchitis, bronchiectasia, cough and other respiratory disease. It have a good effect onpostoperative adhesion,
decrustation and thrombophlebitis etc.
3.Feed industry: this protease can be used together withα-amylase, acid protease, cellulose and glucoamylase. Can widely used to feed the pig, poultry and fish. After adding protease into the feed, the feed can be decompose incertain degree towards artificial control the temperature, moisture, ph value and act time. The protease can directly add into the feed when in small scale feeding. After fully mixture, it can be used to feed the poultry. When mixture, pls. mix it in escalate way to make sure the protease is distribute equality. Usually the adding weight is 0.1-1.0% of the feed.
