preparation example Construction

[0029] The preparation method of special-purpose EM bacteria powder for aquaculture of the present invention comprises the following steps:

[0030] (1) Weigh bran, corn flour, and amino acid powder in proportion, dry heat and sterilize, and make dry matter filler (I). In the step (1), by weight, 700-900 parts of bran and 100-150 parts of corn flour are sterilized by dry heat above 100°C for 0.8-1.2 hours, and mixed to form a dry filler (Ⅰ ).

[0031] (2) Making bacterial liquid nutrient (II): by weight, 55-65 parts of amino acid powder, 2-4 parts of brown sugar, 1.5-2.5 parts of glucose, 0.8-1.2 parts of lactic acid bacteria, and 0.1-0.3 parts of Bacillus licheniformis , 0.1-0.3 parts of Bacillus coagulans, mixed with 350-600 parts of sterile water to make a bacterial liquid nutrient (II). The amino acid powder is sterilized by dry heat above 100°C for 0.8-1.2 hours before mixing, and the sterile water is prepared by filtering and heat sterilizing.

[0032] (3) Add the dry...

Embodiment 1

[0038] 1. Dry heat sterilize 800 kg of bran, 135 kg of corn flour and 60 kg of amino acid powder at a temperature above 100°C for 1 hour, then mix the bran and corn flour to make dry filler (I).

[0039] 2. Prepare sterile water by filter sterilization and heat sterilization.

[0040] 3. Mix 60 kg of amino acid powder sterilized by dry heat in step 1, 3 kg of brown sugar, 2 kg of glucose, 1 liter of lactic acid bacteria, 200 grams of Bacillus licheniformis, and 200 grams of Bacillus coagulans into 450 liters of sterile water to make a bacterial solution Nutrients (II).

[0041] 4. Add 55.5 kg of bacterial liquid nutrient (II) for every 100 kg of dry matter filler (I), and mix and stir evenly in a mixer to make a mixed wet material (III).

[0042] 5. Put the mixed wet material (Ⅲ) into a bag, seal it for anaerobic fermentation for about 10 days, and keep the room temperature at 25-37°C to make the wet fermentation material (Ⅳ).

[0043] 6. Take 100 grams of wet fermentation mat...

Abstract

The invention discloses special EM (Effective Microorganisms) bacteria powder for aquaculture, as well as a preparation method and application of the special EM (Effective Microorganisms) bacteria powder. Bran, corn flour, amino acid powder and the like, which are used as dry matter fillers, are mixed with brown sugar, glucose and the like to obtain a mixture; the mixture is subjected to sealing fermentation at 25-37 DEG C for about 10 days by lactic acid bacteria, bacillus licheniformis and bacillus coagulans, so that fermented materials are prepared; then the prepared fermented materials are dried and crushed and are mixed with bacillus subtilis to obtain a final product. The EM bacteria powder can be directly scattered in a water body to inhibit pathogenic microorganisms through mass propagation of probiotics, decompose harmful substances in the water body, promote the growth of normal floras and beneficial algae in a cultivation ecosystem and keep the ecological balance of the aquaculture water body. The method is adopted to prepare the EM bacteria powder, the fermentation period is short, the process is simple, the equipment investment is low, the materials are convenient to obtain, and the method is easy to implement and is suitable for industrial production and self-production of households.

Description

technical field [0001] The invention relates to the field of microbial preparations, in particular to an EM bacterial powder special for aquaculture and a preparation method thereof. Background technique [0002] EM bacteria (Effective Microorganisms) is the English abbreviation of Effective Microorganisms, also known as probiotics, such as golden bacteria, is a kind of living bacteria with about 80 kinds of microorganisms that are mainly photosynthetic bacteria, lactic acid bacteria, yeasts and actinomycetes. The preparation has the advantages of complex structure, stable performance, and complete functions. It is widely used in agriculture, breeding, planting, environmental protection and other fields. It has achieved obvious economic and ecological benefits and has broad market application prospects. [0003] In view of the strong advantages of EM bacteria in application, various technical products related to EM bacteria have emerged at the historic moment, and the produc...
