Microecological preparation-tetragenous viable bacteria preparation and method for preparing same

Abstract

This invention relates to a micro-ecological agent and the preparation method thereof, belonging to the micro-ecological agent technological field. The preparation of the active bacteria agent of this invention comprises: using L-calcii lactas and four useful micro-organisms of clostridium bytyricum, Lactobacillus casei, bacillus subtilis and saccharomycete as characteristic elements, cultured purely or mixedly by means of universal fermentator, producing active bacteria powder by freeze-drying, and acquiring the finished products by double crossing of the powder at a specific proportion. By using the anaerobic and aerobic characteristics of related bacterial strains, this agent has the following merits: playing the synergy effect in enhancing the disease resistance of marine animals and the water purification of aquaculture, substituting antibiotics fully or partly for the disease prevention and cure in fresh water aquiculture and mariculture, and improving the economic benefits of aquaculture. The L-calcii lactase component can accelerate the husking growth and prevent the disease of soft husk of shellfish marine animals like shrimp and crab. 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

[0001] A micro-ecological preparation-quadruple live bacteria preparation and a preparation method thereof, which belong to the technical field of micro-ecological preparations. technical background

[0002] In recent years, with the rapid development of my country's aquaculture industry and the increasing scale of high-density and intensive aquaculture, high concentrations of aquatic animal excreta in the aquaculture water, bait residues caused by a large amount of bait and arbitrary discharge of sewage have caused The pollution of the natural waters has made the breeding ecological environment worse. Aquatic animals, especially crustaceans such as shrimps and crabs, have a low immune system function and mainly rely on non-specific substances produced by various blood cells such as cohesin lysozyme to exert the body's non-specific immune function. Attacked by pathogenic bacteria and viruses, various diseases occur frequently and reduce the economic benefits ...
