Abstract
The present invention relates to a kind of active rare-earth fodder yeast and production method thereof.This yeast is to add a certain amount of rare earth in substratum, and its production method has promoted the vigorous growth of yeast cell, has suppressed the growth of bacterium, and the fermented product infection rate is reduced greatly, has improved quality product and biological value.Simultaneously, solve rare earth and in livestock industry, mixed uneven problem because of consumption is few with feed.
Description
The present invention relates to microbial fermentation product and production method thereof, particularly a kind of active rare-earth fodder yeast and production method thereof.
At present, the method for producing fodder yeast both at home and abroad has two kinds, and a kind of is cellulose lye with the paper mill, and the wood saccharification liquid of wood-working factory, the molasses waste liquid of saccharification factory or the waste liquid of Gourmet Powder Factory etc. are the liquid submerged fermentation method of substratum.Another kind is the tankage with agricultural byproducts processing factories such as starch factory and oil pressing factorys, is the solid fermentation method of substratum as protein powder, the dregs of fat, dregs of beans etc.It is easily aging that these two kinds of methods all exist bacterial classification, and substratum is easily infected by bacterium, so that influence the deficiency of quality product.
The purpose of this invention is to provide a kind of active rare-earth fodder yeast that adds rare earth in yeast, this zymic production method both can suppress the growth of bacterium, can promote yeast vigorous growth again.
Technical scheme of the present invention is that following steps are finished:
Add rare earth in the yeast.
Earlier rare earth is dissolved in the water, becomes rare earth liquid, then organic substance is joined in the rare earth liquid, make it become the rare earth substratum, yeast is inserted in the rare earth substratum ferment again.
Above-mentioned used rare earth is rare earth nitrate, rare earth chloride and carbonated rare earth.What the present invention preferentially selected for use is rare earth nitrate.Oxide compound in the rare earth nitrate 〉=38%, lanthanum trioxide 〉=21% wherein, cerium oxide 〉=44%, Praseodymium trioxide 〉=16%, Neodymium trioxide 〉=15%, Samarium trioxide 〉=2%, other mixture≤2%.
The total amount of above-mentioned rare earth in substratum is: 1000ppm-8000ppm during solid fermentation, 100ppm-500ppm during liquid fermenting.
Above-mentioned organic substance is dregs of beans, zein, the dregs of fat, blood meal, cellulose lye, starch saccharificating liquid etc.
Above-mentioned bacterial classification can be a yeast, also can be the composite bacteria that yeast and mould are formed.
Show with experiment that after deliberation rare earth is not only a kind of micro-element nutrition to the procreation growth of yeast and mould, and is a kind of activator.In substratum, the yeast and the mould that add rare earth are more vigorous than the growth that does not add rare earth, and speed is fast.Increase more than 30% at each fermentation period inner cell number, the infectation of bacteria rate reduces more than 50% more.
The yeast that is adapted to the rare earth element substratum has cereuisiae fermentum genus, false silk class yeast, Hansenula, Endomycopsis, Geotrichum etc.Mould has Aspergillus, Rhizopus, Mucor etc.
These bacterium have nothing in common with each other to the adaptive faculty of rare earth element, so usage and the consumption of rare earth in substratum also has nothing in common with each other, should look bacterial classification and adjust consumption.Solid medium is adjusted consumption in the scope of 1000ppm-8000ppm.Liquid nutrient medium is adjusted consumption in the scope of 100ppm-500ppm.
Embodiment 1:
During solid fermentation, prescription is:
Dregs of beans 25% dregs of fat 15%
Zein 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.Pack into after mixing thoroughly and ferment in fermentation vat or other container.Carry out dry-cure after waiting to ferment.
Embodiment 2:
During liquid fermenting, prescription is:
100 kilograms of cellulose lye or starch saccharificating liquids, 0.01 kilogram of rare earth, 0.5 kilogram in ammonium sulfate.
Its production method is:
With rare earth and a spot of water dissolution of ammonium sulfate, be mixed in then in spent pulping liquor or the saccharification liquid earlier, insert bacterial classification, feed cleaned air passes, stir fermentation.Concentrate and dry-cure after waiting to ferment.
The active rare-earth fodder yeast that the present invention produces has as stated above not only suppressed the infection of bacterium, has strengthened saccharomycetic vigor, and the effect of feed domestic birds and animals and fish all is better than merely making an addition to effect in the feed with rare earth or common yeast.Our experiments show that:
The rare earth yeast increases production than common yeast more: the milk cow raising gives milk 16.8%, and beef cattle is improved day weight gain 10.2%, and pig is improved day weight gain 12%, and fryer improves day weight gain 8%, and laying hen is improved egg productivity 12.5%.
The present invention is added in rare earth in the substratum before yeast fermentation, not only double effect has been played in the volume increase of microbial growths such as yeast and large animals such as pig, ox, and it is few because of consumption during simple the use in livestock industry to have solved rare earth, easily deliquescence and mix uneven problem.
