Description
Technical Field
The invention relates to bacillus and microbial agent and application thereof, in particular to bacillus bailii and microbial agent and application thereof.
Background
The production and consumption of vinegar in the world is mainly focused on two areas: the European traditional wine production area, mainly Italy and France, and the China-Korean three-kingdom in southeast Asia. The western national table vinegar is mainly brewed by taking grape juice as a main raw material through a liquid submerged fermentation process, and the fermentation is mainly performed by taking acetic acid bacteria as main materials, so that the product has relatively single flavor substance and a single taste. In eastern countries such as China and Korea, vinegar is mainly brewed by taking grains with high starch content such as glutinous rice, sorghum or sweet potato as main raw materials, bran and wheat bran as auxiliary materials and solid fermentation processes of various microorganisms. The main acid of the solid brewing vinegar is acetic acid, organic acid such as lactic acid, succinic acid, pyroglutamic acid and the like, amino acid such as glutamic acid, alanine, lysine and the like, and a plurality of volatile flavor compounds, and the substances endow the vinegar with rich taste and coordinated aroma. In addition, the microorganism participating in fermentation can also produce functional factors such as ligustrazine, flavone, polyphenol and the like, and the health care function of the vinegar is given to a certain extent.
Acetoin, also known as 3-hydroxy-2-butanone, is a food flavor additive, has very rich cheese flavor and ester flavor, gives people pleasant feelings at reasonable concentration, and is a national regulatory food additive (GB 2760-86) which can be used. In addition, acetoin is also a precursor of ligustrazine which is an important functional component of vinegar, and ligustrazine can be generated by the reaction of acetoin and amino compounds, so that the ligustrazine not only has the fragrance of baked nuts, but also has the health-care functions of protecting heart and cerebral vessels, resisting oxidization and the like, and the health-care value of the vinegar is related to the content of the ligustrazine, so that the ligustrazine can be used as a characteristic index for identifying the quality of the vinegar.
At present, many strains for producing acetoin are researched and reported, and mainly include lactobacillus, acetic acid bacteria, saccharomycetes, bacillus and the like. Bacillus belicus is a new species of Bacillus, and research on the Bacillus is also increasing, but the research focus is mainly on plant growth, disease and pest resistance, disease resistance of an induction system and the like.
The invention relates to a preparation method of a high-yield acetoin and flavored bacillus mojavensis direct vat set starter and application thereof in the production of Shanxi aged vinegar, and discloses a method for enhancing the content of ligustrazine in the Shanxi aged vinegar by using the flavored bacillus mojavensis CGMCC 16910 direct vat set starter in the production of Shanxi aged vinegar. The acetoin yield of the flavored bacillus mojavensis CGMCC 16910 utilized by the method is 45.63g/L, and the content of ligustrazine in the finally produced new vinegar is 266.47 mug/mL.

The method for producing vinegar according to claim 7, wherein: the preparation of the first-level seed liquid specifically comprises the following steps: according to the inoculation amount of 1% -10%, inoculating the purified bacillus beijerinckii bacterial liquid in logarithmic growth phase into a culture medium, and culturing at 30-37 ℃ to obtain first-stage seed liquid.
9. The method for producing vinegar according to claim 7, wherein: the preparation of the secondary seed liquid specifically comprises the following steps: heating water to 90-95deg.C by liquid fermentation method, adding rice flour and high temperature alpha-amylase, and maintaining the temperature to obtain mash; then the temperature of the mash is reduced to 45-55 ℃, and saccharifying enzyme is added for heat preservation, thus obtaining saccharified liquid; adding 0.5% -2% of peptone and 0.5% -2% of yeast powder into the saccharification liquid, and sterilizing; cooling to 30-37 ℃, inoculating the first-stage seed liquid according to the inoculum size of 1-10%, ventilating and stirring, and performing pressure maintaining fermentation at 30-37 ℃ to obtain the second-stage seed liquid.
10. The method for brewing vinegar according to claim 9, wherein the step (2) specifically comprises the steps of: mixing and stirring the beer mash, bran and bran, inoculating acetic acid bacteria according to the inoculation amount of 1-10% of the weight of the beer mash, inoculating secondary seed liquid of bacillus bailii according to the inoculation amount of 1-5% of the weight of the beer mash, and carrying out seed-carrying and solid layered fermentation; sealing fermented grains, spraying vinegar and decocting vinegar.
