preparation example Construction

[0030] A kind of preparation method of above-mentioned aquatic products is characterized in that, comprises the following steps:

[0031] (1) Dry Bacillus subtilis powder, Bacillus megaterium and Bacillus circulans at 40-90°C, and dry Candida tropicalis powder at 30-70°C;

[0032] (2) Put the above raw materials into a mixer and mix them evenly, and pack them in paper-plastic and composite aluminum foil bags. The storage temperature should be less than 35°C, and the humidity of the storage environment should be less than 60%.

[0033] The mixer is a twin-shaft paddle-type high-efficiency mixer with a coefficient of variation of mixing uniformity less than 5%.

[0034] The bacterial classification that the present invention adopts and its characteristics are:

[0035] 1. Bacillus subtilis

[0036] Gram-positive, rod-shaped, spore-forming or partial-growing, cysts enlarged but not obvious, 7% NaCl growth, pH 5.7 growth, glucose (+), arabinose (±), starch hydrolysis, nitrate ...

Embodiment 1

[0066] Embodiment 1: the production of compound microecological feed additive

[0067] (1) Take the Bacillus subtilis, Bacillus megaterium, Bacillus circulans and Candida tropicalis powder that were separated by liquid fermentation culture and dried at a temperature of 60-80°C.

[0068] (2) Calculated by weight ratio, take 0.25Kg of Bacillus subtilis powder, 0.40Kg of Bacillus megaterium powder, 0.25Kg of Bacillus circulans powder, and 0.10Kg of Candida tropicalis powder with a mixing uniformity coefficient of variation less than 5% double-shaft paddle-type high-efficiency mixer to mix evenly, packaging paper plastic and composite aluminum foil bags, storage temperature is less than 35 ℃, storage environment humidity is less than 60%.

Embodiment 2

[0069] Embodiment 2: the production of compound probiotics feed additive

[0070] Raw material is with embodiment 1. The ratio of raw materials is: calculated by weight, 0.20Kg of Bacillus subtilis powder, 0.35Kg of Bacillus megaterium powder, 0.20Kg of Bacillus circulus powder, and 0.25Kg of Candida tropicalis powder. Method of making is with embodiment 1 and is made product.

Abstract

The invention discloses aquatic compound microecologics and a preparation method thereof. The compound microecologics is an additive prepared by proportionally mixing four fungi and other fermentation products, and comprises, by weight, 0.20-0.50 part of bacillus subtilis powder, 0.20-0.60 part of bacillus megatherium powder, 0.20-0.50 part of bacillus circulans powder and 0.05-0.30 part of candida tropicalis powder. The compound microecological feed additive has the advantages of simple manufacturing process, easiness to obtain cultures and low cost and has no toxic or side effects and residues. The compound microecological feed additive applied to aquatics can be used as a feed additive so as to improve feed quality, increase crude protein content in feed, decrease coarse fiber content in the feed and improve water quality of aquaculture, thereby being a novel microecologics product which is safe, reliable, pollution-free, purely-fermented and multifunctional.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a composite micro-ecological additive for aquatic products and a preparation method thereof. Background technique [0002] Microecological preparations, also known as microecological regulators, are live bacterial preparations containing a large number of beneficial bacteria made from microbial cells screened from the natural environment and cultured and propagated. At present, the commonly used microecological preparations at home and abroad can be divided into two categories according to their uses: one is intestinal microecological improvers, which are added to feed to improve the composition of microbial communities in the gastrointestinal tract of farmed animals; the other is Water quality micro-ecological improvers, that is, to improve water quality by putting them into water bodies, mainly include photosynthetic bacteria, bacillus, EM bacteria, etc. Different types ...
