Abstract

The invention discloses a compound lactobacillus microbial inoculum. The compound lactobacillus microbial inoculum comprises bacterial manure of the compound lactobacillus microbial inoculum, the lactobacillus microbial inoculum and bacterial manure are used for shorting mushroom fruiting time and improving the mushroom yield. The compound lactobacillus microbial inoculum is prepared from lactobacillus plantarum P-8, lactobacillus acidophilus KT-La9 and lactobacillus plantarum KT-Lp9. The compound lactobacillus microbial inoculum or bacterial manure is mixed into a culture medium used for growing mushrooms, even though the fruiting time of agaricus bisporus is shortened by four days, the yield is improved by 10% or more. The invention further provides a preparation method of the compound lactobacillus microbial inoculum, the method is easy, convenient and practical, and the viable count in the prepared compound lactobicillus microbial inoculum is high.

Description

technical field [0001] The application belongs to the field of biotechnology, and in particular relates to a lactic acid bacteria agent and its preparation method and application. Background technique [0002] Agaricus bisporus (Agaricus bisporus) referred to as Agaricus bisporus, also known as mushrooms, mushrooms, world mushrooms, commonly known as mushrooms, belongs to the genus Agaricus Agaricus, has a certain nutritional and medical value, is currently the world's A kind of edible fungus with the largest cultivation scale and output, its output accounts for about 40% of the world's edible fungi output, and it is also my country's largest export-earning edible fungus. With the increase of market demand, Agaricus bisporus has entered the stage of facilities and large-scale cultivation. [0003] Agaricus bisporus is a kind of grass rot fungus, which has the characteristics of not covering the soil and not producing mushrooms. There are different opinions on the factors of...
