Problems solved by technology

The composition of the existing Beauveria bassiana culture medium is relatively simple, and it is not good for promoting the growth of Beauveria bassiana. There are few designs for the growth process of Beauveria bassiana, and it is easy to be affected by impurities during the cultivation process. Bacterial contamination, therefore, the quality of the obtained conidia of Beauveria bassiana is unstable, the toxicity is weak, and the reproduction cycle is long

Abstract

The invention discloses a medium and culture method of beauveria bassiana. The medium includes a liquid medium and a solid medium. The liquid medium comprises the following components, by weight part, 5-15 parts of glucose, 2-8 parts of yeast powder, 3-10 parts of potato juice, 5-20 parts of peptone, 5-10 parts of silkworm powder, 1-5 parts of potassium dihydrogen phosphate, 1-5 parts of cephalosporin and 20-80 parts of sterile water. The solid medium comprises the following components, by weight part, 5-15 parts of glucose, 5-15 parts of corn flour, 5-10 parts of silkworm powder, 10-20 parts of lactose, 10-20 parts of wheat bran and 1-5 parts of cephalosporin. Beauveria bassiana conidia obtained from the medium have great power of invading host insects, are less polluted by other bacteria, and are high in success rate. The breeding period is short, and the quality of beauveria bassiana conidia is stable.

Description

technical field [0001] The invention relates to the technical field of microorganism culture, in particular to a medium for Beauveria bassiana and a method for cultivating Beauveria bassiana. Background technique [0002] Beauveria bassiana is an entomogenic fungus of the ascomycete class. The main species include Beauveria bassiana and Beauveria b. bassiana. It often produces conidia through asexual reproduction, and the hyphae have transverse septa and branches. Beauveria bassiana can invade 6 orders, 15 families, more than 200 kinds of insects and mites and reproduce in large numbers, and at the same time produce beauveria (non-ribosomal polypeptide toxoid), oosporin (benzoquinone toxoid) and calcium oxalate Crystallized, these substances can cause insect poisoning, disrupt metabolism and lead to death. Among them, Beauveria bassiana is an ascomycete fungus, which can be cultivated and produced industrially, and the molecular spores produced by it can be processed into m...
