preparation example Construction

[0020] Wherein, the preparation method of the microbial bacterial agent may include: inoculating the Bacillus intermedium of CGMCC No. 8839 in the fermentation medium for culturing. Preferably, in each gram of the microbial agent obtained by culturing, the number of viable bacteria of Paleobacterium intermedia whose preservation number is CGMCC NO.8839 can be (5-200)×10 7 CFU, more preferably (20-120)×10 7 CFU. Wherein, the cultivation temperature may be 28-35° C., and the cultivation time may be 10-50 hours.

[0021] Preferably, the preparation method of the microbial agent may also include: mixing the material obtained after culturing in the fermentation medium with an inert solid carrier and a binder; the inert solid carrier includes clay, silicon dioxide, silicon At least one of algal earth, kaolin, attapulgite, montmorillonite, bentonite, talc, white carbon black and calcium carbonate; the binder includes maltose and / or dextrin. Preferably, the amount of the inert soli...

Abstract

The invention provides ochrobactrum intermedium with a collection number CGMCC NO.8839 and a microbial agent. The microbial agent contains bacteria and a culture medium, wherein the bacteria comprise the ochrobactrum intermedium with the collection number CGMCC NO.8839. The invention further provides applications of the ochrobactrum intermedium and the microbial agent to degradation of neonicotinoid insecticides. According to the technical scheme, the residue content of the neonicotinoid insecticides in soil can be effectively reduced.

Description

technical field [0001] The invention relates to the field of agricultural biotechnology, in particular to a Pseudomonas intermedia, a microbial agent and applications thereof. Background technique [0002] Nicotinic insecticides are acetylcholinease receptor inhibitors that act on the central nervous system of insects. They are highly efficient, selective, and safe for mammals, and there is no cross-resistance with most traditional pesticides. Among them, the neonicotinoid compound with insecticidal activity was first discovered by Shell Company, and then the structure was continuously optimized to obtain clothianidol with high insecticidal activity. Research. Currently commercialized neonicotinoid insecticides include imidacloprid, acetamiprid, nitenpyram, chlorothiaprid, thiacloprid, thiamethoxam, clothianidin and dinotefuran. [0003] The output of nicotine pesticides accounts for 15-20% of the global pesticide output. The extensive use of nicotine pesticides has cause...
