Method for largely and rapidly reproducing lactic acid bacteria

Abstract

The invention relates to a method for largely and rapidly reproducing lactic acid bacteria, which comprises the following steps: (1) mixing wormwood or tea-leaf, molasses with common salt in the proportion of 16:8:2 in percentage by weight; (2) filling the mixed wormwood or tea-leaf, molasses and common salt into a plastic film bag, tightening the mouth of the plastic film bag, and spontaneously fermenting at normal temperature; (3) fetching 60kg of molasses and 1kg of common salt and adding 300L of water to stir and dissolve the molasses and the common salt, and then, adding the water into a plastic tank of which the capacity is 3000L to 3000L to prepare a nutrient solution for reproducing the lactic acid bacteria through the suction of a pump; and (4) after 7 days of spontaneous fermentation, taking out a fermentation solution, i.e. a lactic acid bacteria strain stock solution, adding 100L of lactic acid bacteria strain stock solution into the plastic tank, and then adding the nutrient solution of the lactic acid bacteria to 3000L. The invention has the advantages as follows: the technology and the method for largely and rapidly reproducing the lactic acid bacteria by fermenting the wormwood or the tea-leaf are at least 100 times higher than a traditional lactic acid bacteria production technology in speed, and the cost price is only 1 / 100 the cost price of the traditional lactic acid bacteria production technology.

Description

technical field [0001] The invention relates to a method for rapidly multiplying and producing lactic acid bacteria in large quantities. Background technique [0002] Lactic acid bacteria refers to the general term for a class of non-spore-forming, Gram-positive bacteria whose main product is lactic acid. All bacteria that can produce lactic acid from the fermentation of glucose or lactose are collectively called lactic acid bacteria. This is a rather complex group of bacteria, which can be divided into at least 18 genera and more than 200 species. Except for a few, most of them are essential flora in the human body and have important physiological functions, which widely exist in the intestinal tract of the human body. At present, it has been confirmed by biologists at home and abroad that there is a very close direct relationship between intestinal lactic acid bacteria and health and longevity. Lactic acid bacteria are a type of probiotic bacteria that exist in the huma...

Problems solved by technology

At present, the requirements for lactic acid bacteria production equipment are high, the production process is complex, the output is low, and the production cost is high, which is far from meeting the needs of the society.
