The invention provides a traditional Chinese medicine microbial ecological agent for preventing and treating infectious bursal disease of chicken and a preparation method thereof. The preparation method comprises the following steps: adding water to radix isatidis, honeysuckle, forsythia, folium isatidis, humulus scandens, radix scutellariae, dangshen, ageratum, plantain, astragalus membranaceus, angelica sinensis and liquorice, boiling by using high heat, preserving heat for 30-60 minutes by using slow fire, cooling, filtering, collecting filtrate, adding white sugar, boiling, cooling to a normal temperature, then inoculating lactobacillus, zygosaccharomyces bailii and acetobacter xylinum, and fermenting for 3-7 days so as to obtain the microbial ecological agent. After the microbial ecological agent is diluted proportionally, the diluted microbial ecological agent is directly drunk by chicken. The traditional Chinese medicine microbial ecological agent provided by the invention has the effects of resisting viruses, inducing interferon, increasing the quantity of effective microbial communities in intestinal tracts, boosting immunity and improving disease resistance of chickens without toxic or side effects and the like; the preparation method is simple, convenient to use and high in viable bacteria content and has no residues. The traditional Chinese medicine microbial ecological agent provided by the invention has a certain curative effect on infectious bronchitis and henpox and relatively good market prospect.

Genetically modified lactic acid bacteria having a reduced or lacking or enhanced diacetyl reductase activity, acetoin reductase activity and/or butanediol dehydrogenase activity are provided. Such bacteria are used in starter cultures in the production of food products including dairy products where it is desired to have a high content of diacetyl and for reducing or completely removing diacetyl in beverages including beers, fruit juices and certain types of wine, where the presence of diacetyl is undesired.

The invention discloses a microbial compound fertilizer, and belongs to a compound organic fertilizer. The microbial compound fertilizer comprises animal waste, aquaculture pond sludge, a microbial agent, potassium chloride and calcium hydrogen carbonate. The microbial agent comprises azotobacter chroococcum, bacillus laterosporus, silicate bacteria, bacillus megaterium, bacillus cereus, silicate bacteria, lactobacillus and phosphorus-solubilizing bacteria. The microbial compound fertilizer is granular, is convenient to use, can be directly used and also can be used after being diluted in water.

The invention relates to a preparation method of dendrobium officinale fermentation liquid. The method comprises the following steps of (1) preparing food enzymatic hydrolysate; (2) preparing a dendrobium officinale extraction solution; (3) preparing a dendrobium officinale nutrition solution; (4) performing fermentation; (5) performing emulsification. The dendrobium officinale, moringa oleifera powder and various medical and edible materials are matched in a proper proportion, and are sufficiently mixed; then, lactobacilli are added for fermentation; single strains, i.e., the lactobacilli are used in the fermentation process; a purpose-made culture solution is used as the breeding ground; the fermentation efficiency is more sufficiently realized; the combination of sodium chloride and acetic acid is used as a buffer solution, so that the pH value of the solution is enabled to be maintained in the pre-control range in the fermentation process.

The invention discloses a lactic acid bacterium additive for ensiling Lolium multiflorum and a preparation method of the lactic acid bacterium additive, wherein the lactic acid bacterium additive can be used for improving the fermentation quality and nutritional value of an ensilage. The additive is prepared by mixing a first strain and a second strain, wherein the first strain is lactobacillus plantarum (LP), the second strain is any one selected from lactococcus lactis (LL), Weissella confusa (WF) and Weissella cibaria (WB), and the volume ratio of the first strain to the second strain is 1: (1-3). The lactic acid bacterium additive is added into a Lolium multiflorum ensilage when Lolium multiflorum is ensiled, so that the fermentation quality and nutritional value of the ensilage can be greatly improved; the lactic acid bacterium additive is prepared by separating lactic acid bacteria which are high in acid productivity, vigorous in growing and capable of improving the fermentation quality and nutritional value of the Lolium multiflorum ensilage from lactic acid bacteria attached on Lolium multiflorum, is more suitable for ensiling Lolium multiflorum, and is also suitable for popularization and application in the ensiling field.
