Abstract

The invention discloses a strain of Kluyveromyces marxianus used for milk beer production. The strain is Kluyveromyces marxianus A3 deposited at the common microbial center of China Microbial CultureCollection Administration on April 27, 2010, and the accession number of the Kluyveromyces marxianus A3 is CGMCC No. 3781. Further, the invention providesaspecial high-density liquid medium and application thereof and a liquid fermentation agent prepared therefrom. The beneficial effects of the invention are as follows: after the strain is preserved at 0-4 DEG C for 4 days, the liquid culture cancontain more than 1.0*10 <11> viable strains per mL; the source of raw materials is sufficient, the price is cheap, and the burdening is convenient; the adoption of a preparation method of a high-density liquid fermentation agent not only reduces the volume of culture, equipment investment, and production time, but also saves the purchase cost ofstrains, andspecifically, the purchase cost of strains is saved by 260,000 yuan in 2014, 570,000 yuan in 2014 and 756,000 yuan during January to September of 2016.

Description

technical field [0001] The invention relates to the technical field of milk beverage production, in particular to a Kluyveromyces marx strain used for milk beer production, a special culture medium and application thereof. Background technique [0002] Milk beer, also known as "milk champagne", is a new type of sour, refreshing, nutritious and alcoholic milk drink fermented by special lactic acid bacteria and yeast. It has low alcohol content, milky white body, rich malt fragrance, slightly carbonated gas, rich and white foam, and more delicate and lubricated texture. The research and application of yeast are mostly in bread, wine and biopharmaceuticals. There is less research on yeast for fermented dairy products, and there is even no special dairy yeast starter. Contents of the invention [0003] The object of the present invention is to provide a strain of Kluyveromyces marx for milk beer production, its special culture medium and its application aiming at the above-me...
