Abstract

The present invention relates to an application method of rare earth in feed microbe. Said method adds the rare earth elements to microbiological culture medium so as to promote the growth of microbial cells of yeast, etc., inhibit the growth of other bacteria and raise the product quality and biological potency, and at the same time can solve the problem of that a small dosage of rare earth can't be uniformly mixed with feed in animal agriculture.

Description

The method that a kind of rare earth is used in feed microbe

The present invention relates to the application process of rare earth in the feed microbe sweat.

At present, in the feed microbe fermented product, as dusty yeast, enzyme preparation and various culture of strains and production, in culture medium or carrier, do not contain rare earth element, just, be equipped with organic substance or inorganic substances and a certain amount of water of essential constant such as carbon containing, nitrogen, calcium, phosphorus, potassium, sulphur, magnesium and trace element, carry out fermented and cultured at a certain temperature by traditional method.With the product that such method is produced, not only bacterial cell quantity is few, and enzyme activity is low, and aging bacterium is many, and the fermented product difficult quality is improved.

The purpose of this invention is to provide a kind of rare earth element, participate in the microorganism method of fermentation synchronously, make in the fermented product, cytosis, various enzyme activities are improved, and the microbial contamination rate reduces.

The rare earth that the present invention is suitable for is nitric acid rare earth, rare earth chloride and carbonated rare earth.What the present invention preferentially selected for use is nitric acid rare earth.Oxide in the nitric acid rare earth 〉=38%, in oxide, lanthana 〉=21%, cerium oxide 〉=44%, praseodymium oxide 〉=16%, neodymia 〉=15%, samarium oxide 〉=2%, other mixture≤2%.

Technical scheme of the present invention is that following steps are finished:

In culture medium, add rare earth.

Earlier rare earth is dissolved in the water, becomes rare earth liquid, then organic substance and other inorganic salts are joined in the rare earth liquid, make it become the rare earth culture medium, microorganism fungus kind is linked in the rare earth culture medium ferments again.

The consumption of above-mentioned rare earth in culture medium is: 1000PPm-8000PPm during solid fermentation, 100PPm-500PPm during liquid fermentation.

Above-mentioned organic substance is a dregs of beans, corn protein powder, the dregs of fat, blood meal, sulfite liquor, starch saccharificating liquid, large malt sacchariferous liquid etc.

Above-mentioned bacterial classification can be a Blastocystis, also can be that Blastocystis and mould Pseudomonas, actinomyces, photosynthetic bacteria belong to the compound bacteria that is made up.

Show with experiment after deliberation, rare earth is not only a kind of micro-element nutrition to the last procreation growth of respectively stating bacterium, and be a kind of activator, the microorganism that adds rare earth in culture medium is more vigorous than the growth that does not add rare earth, speed is fast, increase more than 30% at each fermentation period inner cell number, the growth of pathogenic bacteria is suppressed, and has reduced its infection rate more.

Above-mentioned various bacterium has nothing in common with each other to the accommodation of rare earth element, so usage and the consumption of rare earth in culture medium also has nothing in common with each other, should look bacterial classification and adjust consumption, and solid medium is adjusted consumption in the scope of 1000PPm-8000PPm.Fluid nutrient medium is adjusted consumption in the scope of 100PPm-500PPm.

Embodiment 1:

During the saccharomycete solid fermentation, prescription is:

Bean powder 25%, the dregs of fat 15%, corn protein powder 55%, ammonium sulfate 4.9%,

Rare earth 0.1%

Per 100 kilograms of above-mentioned material add 60 kilograms in water.

Its production method is:

Earlier rare earth and ammonium sulfate are dissolved in the water, admix the organic substance in the prescription then, insert bacterial classification, ferment in pack into after mixing thoroughly fermentation vat or other container.Carry out dry-cure after waiting to ferment.

Embodiment 2:

During liquid fermentation, prescription is:

100 kilograms of saccharification liquid, 0.01 kilogram of rare earth, 0.5 kilogram in ammonium sulfate, 0.05 kilogram of potassium dihydrogen phosphate.

Its production method is:

Earlier with rare earth and ammonium sulfate, potassium dihydrogen phosphate with a spot of water-soluble separating, be mixed in then in the saccharification liquid, insert bacterial classification, the feeding cleaned air passes stirs fermentation, concentrates and dry-cure after waiting to ferment.

The feed product that the present invention produces has as stated above not only suppressed the infection of pathogenic bacteria, has strengthened the vigor of microbial cell and enzyme, and the effect of feed domestic birds and animals and fish effect of the common micro-organisms feed of excellent dried no rare earth element all.Our experiments show that:

The microbiological feed of rare earth of feeding increases production than the microbiological feed of no rare earth more: milk cow is improved the output of milk 16.8%, beef cattle and improves that daily gain 12%, fryer improve daily gain 8%, laying hen is improved egg production 12.5%.

The present invention is added in rare earth in the culture medium before the microbiological feed fermentation, not only double effect has been played in the volume increase of large animals such as microbial growth and pig, ox, and solved the problem of mixing inequality in animal husbandry when rare earth uses merely because of few, the easy deliquescence of consumption.

Claims

1, the method used in feed microbe of a kind of rare earth is characterized in that having added rare earth element in culture medium.

2, the method used in feed microbe of rare earth according to claim 1 is characterized in that the rare earth of using is nitric acid rare earth, rare earth chloride and carbonated rare earth.

3, the method for in feed microbe, using according to right 2 described rare earths, it is characterized in that earlier rare earth being dissolved in the water, become rare earth liquid, then organic substance and other inorganic salts are joined in the rare earth liquid, make it become the rare earth culture medium, microorganism fungus kind is linked in the rare earth culture medium ferments again.

4, the method used in feed microbe of rare earth according to claim 3 is characterized in that the consumption in the rare earth culture medium is: 1000PPm-8000PPm during solid fermentation, 100PPm-500PPm during liquid fermentation.

5, the method used in feed microbe of rare earth according to claim 3 is characterized in that the microorganism fungus kind of inserting is that Blastocystis or female Pseudomonas and mould Pseudomonas, actinomyces, photosynthetic bacteria belong to the compound bacteria of being formed.
