Aquatic Phytase—Neutral Thermostable phytasePlant material of aquatic feed contains a large number of phytic acid phosphorus, which cannot be utilized by aquatic animals, and chelate Zn, Fe, Ca and other mineral elements, amino acids, starch and other nutrients. Phytic acid and its chelate cannot be degraded in aquatic animal intestines, and large amount of nutrients such as phosphorus and nitrogen emits into directly into water bodies, which exacerbate the eutrophication of water, lead to aquatic animals living environmental deterioration by reason of microbial breeding and a lack of oxygen. The phytase has been widely used in livestock and poultry feed, but because of the huge difference of physiological structure and living environment, which makes the application of phytase in aquaculture feed has been controversial.  So far, Challenge Group has successfully solved the three major bottleneck of phytase in the use of aquatic feed.  ·Play a role in neutral intestinal condition of aquatic animal.   ·Resist high temperature of aquatic feed processing and granulating   ·Play a role in aquatic animals at low temperature of 20~30℃Product Formulations and Enzyme Activity DefinitionAquatic Special Phytase1,000U/g~3,000U/gEnzyme Activity DefinitionOne phytase activity unit (U) is defined as the amount of enzyme which liberates 1µmol inorganic phosphorus from 5.0mmol/L sodium phytate solution per minute at pH 7.0 and 30℃ un...
Quenching enzyme - aquatic special compound enzymesThe harm of gram-negative bacteria to aquatic animals:According to gram staining, bacteria can be divided into gram negative bacteria and gram positive bacteria. Among them, a lot of important pathogenic bacteria related to aquatic animal belongs to gram-negative bacteria. Gram-negative bacterial disease, as the most serious disease harming aquatic animals in China, which has a lot of pathogenic species and harm widely endemic areas aquatic breeding category, has caused great economic losses in aquaculture. The pathogen  which causes bacterial disease of aquatic animals has vibrio anguillarum, Vibrio parahaemolyticus,algin vibrio, Aeromonas punctata, Aeromonas hydrophila, Flavobacterium columnare,Edwardsiella tarda, etc, see table 1.Tab. 1 Main gram-negative bacteria of aquatic pathogenicQuorum sensing and gram-negative bacteria quenching enzymes:Intestinal bacteria often produces and releases specific extracellular signal molecules in the gastrointestinal tract, signaling molecules accumulating to a certain concentration, can induce bacteria control bacteria molecular and cellular response, which is called bacterial quorum sensing. Quorum sensing plays an important role to maintain the normal function of bacteria, and regulate gene expression,as shown in figure 1. Quenching enzyme can degrade gram-negative bacterial quorum sensing signal molecules, destroy the quorumsensing, influence bacteria colonize, break biofilm fo...
