Embodiment
A compound subtilis slow releasing tablet, by weight percentage, its component comprises: the former powder 2~9% of subtilis, SPC-D 73~96%, sustained release dosage 1~10%, stablizer 1~8%.Preferred ingredient comprises: the former powder 3~8% of subtilis, SPC-D 78~93%, sustained release dosage 3~8%, stablizer 1~6%.Further preferred ingredient comprises: the former powder 4~7% of subtilis, SPC-D 83~90%, sustained release dosage 4~6%, stablizer 2~4%.Most preferred composition comprises: the former powder 6% of subtilis, SPC-D 86%, sustained release dosage 5%, stablizer 3%.
Described sustained release dosage is one or more the mixture in sodium alginate, HPMC (HPMCK4M), ethyl cellulose, polyvinyl alcohol, and preferred sustained release dosage is sodium alginate.The mixture of one or more in diatomite, disodium ethylene diamine tetraacetate, white carbon black, polyvinylpolypyrrolidone, methylcellulose gum of described stablizer, preferred stablizer is disodium ethylene diamine tetraacetate.
Subtilis in the former powder of described subtilis is a kind of rod-short, without pod membrane, peritrichous, the gram positive bacterium that can move, it is extensively distributed in the organism of soil and corruption, easily withered grass, soak in juice and breed, available protein, multiple sugar and amylolysis tryptophane form indoles.Subtilis can consume the organic matter in water body in a large number, is translated into small molecular organic acid, ammonia etc., therefore can effectively reduce organic content in water after using, accelerates decomposition, the conversion of residual bait, ight soil etc. in culturing pool; Meanwhile, improve harmful blue-green algae and spread unchecked the water turbidity problem causing, there is very strong Function For Purifying Water.But subtilis is the chmosynthetic heterotrophs microorganism of strict aerobic growth, and improper use or excessive meeting cause water hypoxia.The former powder of described subtilis is glucose embedding.
Described SPC-D can effectively increase Dissolved Oxygen in Water in aquaculture water management; The advantage of SPC-D is the stability of storage and with the good compatibleness of other composition etc., aspect commercial use, conventionally with materials such as vitriol and silicate, wrapped up, the SPC-D that obtains dressing improves it and joins middle side for the requirement of storage stability at Industrial products.
