Method for rapid propagation of lactic acid bacteria in industrial production

Abstract

The invention discloses a method for rapid propagation of lactic acid bacteria in industrial production, which comprises equipment sterilization, medium preparation and cultivation production; whereinthe equipment sterilization step comprises: S21: placing a preparation barrel, a stirring rod and a breeding barrel in sequence into a sterilization barrel, and placing the sterilization barrel backinto a sterilization pot; the medium preparation comprises the following steps: S12: weighing seasonal vegetables, white sugar, brown sugar, salt, peptone, and dipotassium hydrogen phosphate at mass ratio of 6:1:1:1:1:0.2 for preparation, and placing in the preparation barrel; the cultivation production includes the following steps: S13: taking pure water, brown sugar, white sugar, medium and lactic acid bacteria stock solution at a mass ratio of 90:1:1:0.8:10, wherein the lactic acid bacteria stock solution is used for standby. By setting the equipment sterilization step, the medium preparation step and the cultivation production step, the method for rapid propagation of lactic acid bacteria in industrial production solves the problems that the cost of direct use of the lactic acid bacteria product sold in the market is high, the existing lactic acid bacteria propagation method cannot effectively control foreign bacteria and lactic acid bacteria cannot grow normally.

Description

technical field [0001] The invention relates to the technical field of lactic acid bacteria, in particular to a method for rapid propagation of lactic acid bacteria in industrial production. Background technique [0002] Lactic acid bacteria is a general term for a class of bacteria that can use fermentable carbohydrates to produce a large amount of lactic acid. These bacteria are widely distributed in nature and have rich species diversity. They are not only used for research on classification, biochemistry, genetics, molecular biology and genetic engineering. It has important academic value in theory, and it also has extremely high application value in important fields closely related to human life such as industry, agriculture and animal husbandry, food and medicine. In addition, some bacteria in this kind of bacteria are pathogenic bacteria of humans and animals, so they have received great attention and attention. All bacteria that can produce lactic acid from the ferme...
