Embodiment Construction

[0022] The present invention will be described in further detail below through specific examples.

[0023] (1) Isolation, screening and identification of Bacillus licheniformis W10

[0024] Tomato plants (roots with soil) were collected from vegetable fields in the suburbs of Yangzhou, and the top soil on the roots was shaken off after being brought back to the laboratory. The tomato roots still stuck to the fine soil were cut off, and the collected rhizosphere soil samples were collected.

[0025] Soil microorganisms were isolated using the plate dilution coating method. Cut the collected tomato root system into small sections of about 4mm, weigh 10g and put it into a conical flask filled with 90mL sterile water, vibrate at 160r / min for 30min, and obtain 10 -1 Concentration of soil dilution solution, and then sequentially diluted 10 -3 -10 -7 Concentration gradient soil suspension. Draw 100 μL and spread on NA medium (peptone 10g, beef extract 3g, sodium chloride 5g, agar...

Abstract

The invention relates to a bacillus licheniformis used as a pesticide surfactant and an application thereof, belonging to the field of biological control and pesticide research and application in the plant protection discipline. The bacterial strain of the present invention is a high-efficiency biocontrol bacterium isolated and screened from plant rhizosphere soil—Bacillus licheniformis ( Bacillus licheniformis ) W10 strain, the preservation number of this strain in China General Microorganism Culture Collection Management Center is CGMCC No.14859. The present invention uses soybean cake powder, cornstarch, etc. as the substrate for the fermentation medium, and the prepared bacterial strain fermentation liquid bacterial agent can improve the surface tension of the pesticide, reduce the contact angle, have a good surfactant function, and also have the effect of preventing and controlling plant diseases. effect. Therefore, the fermented broth microbial agent of the present invention can not only be used as a surfactant in the processing and preparation of pesticide suspensions, but also can prevent and control diseases, showing broad application prospects.

Description

technical field [0001] The invention relates to the surface activity of bio-control bacterial fermentation culture, and belongs to the field of bio-control and pesticide research and application in the field of plant protection. It specifically relates to a bacillus licheniformis used as a pesticide surfactant and an application thereof. Background technique [0002] Bacillus spp., as an important class of biocontrol bacteria, can produce a variety of antibacterial and antibacterial substances, including bacteriocins, cell wall degrading enzymes, antibacterial proteins, lipopeptide antibiotics, polyketides and polypeptides etc., have the potential to prevent and control plant diseases, and are also the main source of biological control bacteria. At present, researchers focus on various antibacterial active substances in the screening of biocontrol bacteria. However, there are many kinds of fermentation metabolites of biocontrol bacteria. In addition to producing antibacteri...
