Abstract

The water purifying bacterial preparation is environment friendly composite live bacterial preparation developed based on the aquatic animal raising requirement and by means of modern biotechnology. The water purifying bacterial preparation is prepared with Bacillus subtilis, lactic acid bacteria, saccharomycetes, actinomycete, filamentous bacteria, etc. and through screening, domesticating, rejuvenation and culturing. By means of advanced vertical low temperature freeze drying and microcapsule technology, the water purifying bacterial preparation is prepared into composite freeze dried microcapsule powder with composite flora in dormant state at normal temperature for easy transportation and storing. After being thrown into water in the temperature higher than 15 deg.c, the live flora will revive, disintegrate and propagate fast to form dominant flora for purifying water effectively. The water purifying bacteria are salt, acid, base and oxidation tolerant.

Description

The preparation of water purification bacterium and the method for repairing aquaculture environment

Water purification bacterium is a new generation of green environment-friendly type composite bacteria water quality cleansing agent of using the modern biotechnology exploitation, be according to aquatic products ecologic breeding demand for development, select training viable bacteria bacterial classification meticulously from nature, by repeated screening, the domestication rejuvenation, a kind of complex microbial community that cultivation forms is mainly with compositions such as subtilis, milk-acid bacteria, yeast, actinomycetes, thread fungus, nitrifier, nitrococcus and denitrifying bacterias.Water purification bacterium adopts advanced upright frozen drying technology and microcapsulary, make microcapsule composite bacteria lyophilized powder, at normal temperatures, composite flora is in dormant state, is easy to transportation, stores, render to water body after, water temperature is more than 15 ℃, dormancy viable bacteria and microcapsule viable bacteria can very fast recoveries and the disintegration breeding, and in the water quality overfertilization, pond water aged pond bottom can form dominant microflora rapidly.Water purification bacterium has moisture-proof, salt tolerant, acid and alkali-resistance, resistance to oxidation characteristic, make its detergent power stronger to water body, decomposing hydrogen sulfide, ammonia nitrogen, nitrite and small organic molecule to greatest extent, reduce BOD, COD in the water body, fundamentally eliminate the water quality hidden danger that degenerates, strengthen water body self-purification ability, water body is reached stablize nontoxic eubiosis state.

[effect]

1, fast, thoroughly purify water harmful ammonia nitrogen, nitrite in the degradation water, objectionable impuritiess such as removal of hydrogen sulfide;

2, residual bait, movement in the efficient water of decomposition are eliminated sludge underwater, improve water quality;

3, keep water body probiotic bacterium population quantity, suppress field planting and the invasion and attack of other pathogenic bacterium;

4, stablize water pH value, trace element supplement keeps probiotic bacterium and planktonic organism ratio balance in the water, suppresses the breeding growth of harmful algae.

[characteristics]

1, water purification bacterium adopts the dry concentration of vacuum and low temperature quick freezing, viable bacteria content height, long storage time effect stability;

2, that the special thalline of part is carried out the microcapsule bag is processed for water purification bacterium, thus can be acidproof, resistance to oxidation, high temperature resistant (100 ℃), anti-extruding;

3, water purification bacterium need not activate, behind the input water body, and very fast recovery of dormancy viable bacteria and microcapsule viable bacteria and disintegration, and growth and breeding Cheng Shuizhong dominant microflora.

[physicochemical character] tawny powder.

[main component] subtilis, milk-acid bacteria, yeast, actinomycetes, thread fungus, nitrifier, nitrococcus, denitrifying bacteria, biological flocculant.

[active constituent content] every gram contains probiotic bacterium 2 * 10 ⁸Individual.

[use range] is applicable to all seas, fresh-water fishes, shrimp, crab, shellfish, ginseng breed nursery pond and growing pond, is particularly useful for aging pond of water quality that does not have the external source water body to replenish for a long time and the water quality overfertilization pond that too high, the frequent anoxic of cultivation density is raised the nose above water to breathe, disease takes place frequently.

[usage] evenly splashes water purification bacterium with full pond, Chi Shui dilution back.

[consumption]

1, improve water quality: every mu of water surface (1 meter of the depth of water) restrains with water purification bacterium 250-500, multiplicable splashing when high temperature season or water quality deterioration.

2, grow seedlings: every cubic metre of water body 1-2 gram of splashing.

[attention]

1, throws in pharmaceutical chemicals and the antibiotic medicine that bans use of germicidal action in " water purification bacterium " first three day, back five days;

2, in the use, the dissolved oxygen in water amount should remain on more than 3 mg/litre, uses in back 3 days and does not change water;

Water temperature should reach more than 15 ℃ when 3, throwing in, and throw in best fine high noon.

[summary of the invention]

Probiotics of the present invention and preparation method thereof, as follows:

1. fresh chicken manure is positioned over shady and cool place and carries out air-dryly, when treating that water content is 18-20%, collect standby.

2. 60 mesh sieves select rice bran, and are standby.

3. get EM bacterium bacterium liquid, standby.

4. get 1., 2., 3., brown sugar and water, by 45: 30: 2: 1: 22 mixed stirred.

5. will 4. pour the fermentation hole into, sealing and fermenting 10-15 days, shine dry grinding then, make fertilizer composite bacteria auxiliary material through the choosing of 80 mesh sieves, standby.

6. the diatomite of 80 mesh sieves choosing is standby.

7. getting lay-by material 5. and 6. mixes in 1: 1 ratio is composite.

The present invention has strong operability, with low cost, effect is remarkable, to the water surrounding non-secondary pollution, aquatic animal is had no side effect, the aquaculture bottom environment there are advantages such as obvious repairing effect, be to comply with current social back to nature, treasure water and life, pursue green food, the development healthy aquaculture, the only way of realizing healthy consumption.
