This agent is characterized of being nontoxic, free from side effects, nonpersistent, without secondary pollution and no drug tolerance, and will have a wide commercial application in the fresh water aquiculture mariculture.
Description
Technical field
A kind of probiotics---tetragenous viable bacteria preparation and preparation method thereof belongs to the probiotics technical field.
Technical background
In recent years, along with developing rapidly of China's culture fishery, the expansion day by day of the aquaculture scale of high-density, intensification, the aquatic animal movement of aquaculture water middle and high concentration, the throw something and feed pollution in the natural waters that any discharging of bait remnants that bait causes and sewage causes in a large number go from bad to worse the breeding ecological environment.Aquatic animal is Crustacean such as shrimp crab especially, function of immune system is low, main non-specific material such as the lectin N,O-Diacetylmuramidase that relies on various hemocytes to produce waits the non-specific immune function of bringing into play body, in the aquaculture water environment that worsens, be subject to the attack of malignant bacteria and virus, make all kinds of disease pilositys, reduce the culturing economic benefit.Aquatic animal disease especially virus disease major part all develops soon, and harm is big.The common method of preventing and treating be use some microbiotic and chemical synthetic drug to water body carry out disinfection, purifying treatment, to killing of germ in environment and the aquatic animal body, thereby reach the effect of control disease.This method comparatively seriously reaches infectation of bacteria for some breeding environment deterioration certain control action kou, but for most of nurseries, because the aquatic product sprout resistance against diseases is very low, and in case illly mass mortality will occur, make the no obvious effects that heals with medicine.
Microbiotic and chemical synthetic drug life-time service or abuse not only cause the resistance resistance of pathogenic bacteria more and more obvious, and dosage also increases thereupon, result of use worse and worse, even invalid, and cause medicine residual in fishery products, reduced the quality of fishery products.In addition, microbiotic and chemical synthetic drug are when killing the pathogeny bacterium, also disturbed in the aquatic animal body and the breeding of the normal growth of aquaculture water beneficial microbe colony, weaken the anti-disease ability of aquatic animal self, make pollutent and residual bait at the bottom of water body and the pond can not get decomposing timely and effectively, water quality runs down, and destroys the eubiosis of water body, thereby brings out new round disease.Therefore, microbiotic and pharmaceutical chemicals are a kind of passive diseases prevention and treatment ways, can not fundamentally improve the resistance against diseases of aquatic animal, and when it controlled disease as a kind of emergent means, counter productive was conspicuous.
The control of carrying out the aquatic animal disease with probiotics (Microbial ecological agent) is a kind of novel method that developed recently gets up, have nontoxic, have no side effect, the advantage of noresidue.The microniological proudcts that probiotics is based on the microecological balance theory, the theoretical and little bionomic control of little ecoalimental is theoretical and grow up, it is controls of a kind of active form to the control of Animal diseases, adjust aspects such as the inherent nutrition of animal body, immunity, growth-stimulating, biological antagonist by profitable strain in the preparation and bringing into play the microecological balance of important effect, suppress the growth of pathogenic bacterium, promote the growth of animal self beneficial microorganism, strengthen the capacity of self-regulation of its little ecology, the generation of control and minimizing disease improves the host health level.The probiotics of using in aquaculture can also improve water quality by to the decomposition of water body objectionable impurities, the inhibition of pathogenic bacteria and the cultivation of water body profitable strain, keeps the water ecology balance.
The originally diseases that are used for the treatment of human body of probiotics more, probiotics begins to be used for the diseases prevention and treatment of cultivated animals subsequently, and the microbe species that is used to prepare feeding micro-ecological preparation is also increasing, is widely used.FDA (FDA) in 1989 and U.S. feed control official association have announced can directly feed and be commonly considered as safe microbial strains list, has 41 kinds, and year usage quantity is more than 8000 tons.China Ministry of Agriculture also announced 15 kinds of feed level microbe additive bacterial classifications that can directly use such as lactobacterium casei, subtilis, yeast saccharomyces cerevisiae in 2003.At present, domestic probiotics is mainly used in the livestock cultures such as pig ox chicken, and the application in the fishery products animal cultivation is in the starting stage.
The probiotics of using in aquaculture can be divided into two big classes by the quantity of contained microbe species, and promptly single bacterial strain type and many bacterial strains are compound.Single bacterial strain type such as photosynthetic bacteria preparation, bacillus preparation etc. only contain a kind of microorganism, do not have the advantage of many synergistic bacteriums effect, comparatively speaking the existence effect single, act on unabiding limitation.Therefore, the application of many bacterial strains slurriable combination in aquaculture is more, and common have employing genus bacillus, nitrobacteria or photosynthetic bacterium etc. to be mixed in proportion the slurriable combination that forms.Concerning the preparation of this type of slurriable combination, the selection of microbe species, compatibility and preparation technology are crucial, directly influence the effect of preparation.
At present common used for aquiculture probiotics such as photosynthetic bacteria preparation, bacillus preparation, nitrobacteria preparation etc., mainly be utilize remaining bait excessive in the microbiological degradation water bodys such as photosynthetic bacterium, genus bacillus, nitrobacteria, drain refuse, plant and animal residues etc. is to the deleterious organic and inorganic substance of aquatic animal, inhibition growth of pathogenic bacteria, the improvement by the aquaculture water environment reaches the prevention effect to disease.In addition, preparation that has such as photosynthetic bacteria preparation, nutritive substances such as its microorganism self rich in proteins by being eaten to animal supplements the nutrients, promote growth, strengthen the disease resistivity.Therefore, these products are by realizing from the angle of improving water body environment or extra-nutrition to the control of aquatic animal disease, not directly by participating in the adjustment of microecological balance in the aquatic animal body, suppress the growth of pathogenic bacterium, promote the growth of animal self beneficial microorganism, strengthen the capacity of self-regulation of its little ecology, improve aquatic animal self resistance against diseases.Thus, based on above-mentioned background, have adjustment, the promotion growth of participating in microecological balance in the aquatic animal body directly concurrently if can develop, can improve simultaneously the probiotics of water quality again, be applied to the diseases prevention and treatment of aquaculture, then to reducing the use of microbiotic and chemicals, production pollution-free green fishery products, it is significant to improve the culturing economic benefit.
