Background technology
Nineteen sixty-five Lilley and Stillwell at first use probiotics (Probiotics), and it is defined as " by a kind of microorganism secretion, stimulating the material of another kind of growth of microorganism ".1974, Parker thinks " probiotics is a microbiological materials of keeping microbial balance in the intestinal ". probiotic bacteria has overcome the particularly negative effect brought of antibiotic of non-nutritive additive, it is pollution-free, noresidue, anti-disease, promotes the natural additive of growth of animal, has obtained using widely in feed industry.It is generally acknowledged that probiotic bacteria just is meant can survive in organism (mainly being humans and animals), and a quasi-microorganism useful to host's life and health generally is called probiotics to probiotics viable bacteria preparation or the microorganism formulation that contains culture of microorganism.First people just begin to recognize that microorganism and product thereof can exert an influence to body from eighties of last century, and screening has obtained many microorganisms that are considered to probiotic bacteria from microorganisms such as antibacterial, fungus, yeast.Probiotic bacteria is mainly used in the balance of keeping microecosystem in the animal body, does not promptly set up as yet under the situation of good intestinal microflora children domestic animal in age, uses probiotic bacteria to reduce the animal production loss; Probiotic bacteria can also partly substitute antibacterials, by helping to recover the balance of microecosystem in the animal body, reaches the purpose of treatment Animal diseases.Probiotic bacteria commonly used at present has lactobacillus, Bacillus coagulans etc., and its beneficial effect is:
1, to the Nutrition of animal: lactobacillus can synthesize the required multivitamin of animal body, as thiamine, riboflavin, nicotinic acid, pyridoxol, pantothenic acid, folic acid, vitamin B12 etc.Estimate that the microorganism on the caecum can provide 25%~30% of animal vitamin needs amount, can satisfy the needs of body to vitamin substantially.The volatile fatty acid that lactobacillus produces also makes intestinal pH value and redox potential reduce for big intestinal mucosa metabolism provides the energy, helps the absorption of mineral calcium, ferrum, magnesium, zinc etc.
2, suppress the breeding of pathogen: acid products such as the lactic acid that lactobacillus produces, acetic acid can suppress the pathogen growth and breeding.Lactobacillus can produce the plain material of bacterioid, and pathogen is had inhibitory action.The molecular weight that the bacillus acidophilus produces is 3500 peptide, can suppress the synthetic of e. coli dna, can suppress the growth of a series of Gram-positives and negative pathogen.The bacillus acidophilus can produce H
2O
2, the growth and breeding of pathogenic bacterium such as inhibition staphylococcus can also produce biacetyl, and this chemical compound has inhibitory action to many pathogen.Bacillus cereus can produce volatile fatty acids such as acetic acid, propanoic acid, butanoic acid in its growth course, these acids can reduce the animal intestinal pH value, can effectively suppress the pathogen growth.Produce a small amount of antibiotic substance one bacitracin, harmful microorganism is risen suppress and killing action.Bacillus cereus can consume a large amount of oxygen, keeps the intestinal anaerobic environment, suppresses the pathogenic bacterium growth, and the normal ecological balance of intestinal is kept in the effect of balance and stability lactobacillus.
3, improve animal immunizing power: with the lactobacillus fermentation product ablactational baby pig of feeding, the IgG level obviously raises in the piglet serum.
4, the characteristics of Bacillus coagulans and effect show: good stability.Acidproof, salt tolerant, high temperature resistant (100 ℃) and anti-extruding in pelletization and all can keep high stability by the acid stomach environment, can produce vitamin.Bacillus cereus can produce vitamin B group such as B1, B2, B6 and vitamin C, vitamin K in the growth and breeding process, for animal provides vitamin.Produce multiple digestive enzyme: Bacillus coagulans has the very strong protease of secretion, lipase and amylase activity, thereby can replenish the deficiency of intestinal endogenous enzymes.Can also produce phytase, promote animal the utilization of phytate phosphorus and digesting and assimilating to fat.The amino oxidase that produces and the enzyme of decomposing hydrogen sulfide can be oxidized to indoles nontoxic, harmless material, thereby reduce the concentration and the stink of ammonia, hydrogen sulfide in the poultry house, reduce environmental pollution.
About the research of thalline microcapsule, be the advanced technology that develops rapidly in recent years, it is widely used in many fields with own unique advantage.The micro encapsulation that just has the eighties in 20th century researcher to carry out lactobacillus is explored, Pranee carries out micro encapsulation as the wall material to lactobacillus with sodium alginate, the microcapsule of gained is used for the production of lactic acid, and fertility performance is good, and this lactobacillus micro-capsule can be reused.External at present relevant laboratory report can utilize lactobacillus micro-capsule cell mixing probiotics leaven, yoghourt, extracellular polysaccharide, lactic acid, the production of bacteriocin.
