Abstract

The invention relates to a lactic acid bacteria growth promoting agent and belongs to the technical field of microorganisms. The lactic acid bacteria growth promoting agent is mainly prepared from rawmaterials in parts by weight as follows: 30-40 parts of starch, 30-50 parts of sugar, 5-10 parts of yeast extract powder, 1.2-1.8 parts of isomaltooligosaccharide, 0.2-0.8 parts of fructooligosaccharide and 8.3-12.7 parts of inorganic salt. With the adoption of the growth promoting agent, growth of lactic acid bacteria in prawn intestines can be obviously promoted, growth and propagation speed oflactic acid bacteria is increased, the viable count of the lactic acid bacteria in the prawn intestines is increased, growth and propagation of pathogenic bacteria such as vibrios and the like are inhibited, prawn growth is promoted, and survival rate and yield of prawns are increased.

Description

technical field [0001] The invention relates to the technical field of microorganisms, in particular to a lactic acid bacteria growth promoter and its preparation method and application. Background technique [0002] Vibrio is a normal flora in the intestinal tract of prawns, and it is also an opportunistic pathogenic bacterium of prawns. Vibrio can utilize as many as 44 carbon sources. Therefore, Vibrio can preferentially use organic matter in the feed to reproduce, inhibit the growth of beneficial bacteria such as lactic acid bacteria, and make Vibrio in the shrimp intestine dominant. When there are a large number of Vibrio in the intestinal tract of prawns, the growth of prawns is inhibited, the immunity is low, and the stress of the external environment is easy to get sick or even die. [0003] In shrimp farming, the number of lactic acid bacteria in the intestinal tract of shrimp can be maintained by mixing and feeding lactic acid bacteria, so as to reduce the pH value...
