The invention discloses the application of sanguinarine in the inhibition and removal of multi-drug-resistant Providence recei biofilms, and is used to solve the drug resistance of drug-resistant Providence recei biofilms and the formation of biofilms that are difficult to remove once formed. technical problem. According to the fact that sanguinarine has good biofilm inhibitory and scavenging effects on Providencia revei, it can inhibit the formation of biofilm of Providencia revei, and the minimum inhibitory concentration of biofilm is 7.81 μg / mL. Sanguinarine can effectively remove mature Providencia reinhardtii biofilm, and the minimum biofilm removal concentration is 125μg / mL. It uses the natural product sanguinarine to inhibit and clear the biofilm of the multi-drug-resistant Providencia raptorii, which can effectively alleviate or solve the difficulty in the treatment of infections caused by the biofilm of Providencia reinhardtii, and improve the cure rate. Inhibiting the formation of Providencia reinhardtii biofilms and clearing mature biofilms provides new lead compounds with important practical significance.

The invention discloses the application of luteolin in inhibiting the growth of multi-drug-resistant Providencia rettgeri. According to the fact that luteolin has a good in vitro killing effect on multi-drug-resistant Providencia rettgeri, it can inhibit multiple The growth of drug-resistant Providencia rettgeri, and the minimum bactericidal concentration is 30 ~ 250 μg / mL, the minimum inhibitory concentration is 15 ~ 125 μg / mL, the present invention proposes that luteolin is effective against multidrug-resistant Providencia rettgeri The inhibitory effect of S. spp. has wide application value in medicine and other fields.

The invention discloses a root-knot nematode biocontrol bacterium, a biocontrol bacterium agent and applications thereof. The biocontrol bacterium is Providencia rettgeri (Providencia rettgeri) strain UN06, and the preservation number is CGMCC No.10246. The present invention utilizes the fermented liquid obtained by the fermentation of the Providencia rettgeri UN06 strain to mix evenly with adsorption carriers such as bacterial residue and peat and urea, a nutrient substance required for bacterial growth, and then granulate to prepare the UN06 granule. The control effects of applying 100 kg of UN06 granules per mu on tomato root-knot nematode, cucumber root-knot nematode and tobacco root-knot nematode were 90.17%, 88.66% and 85.98%, respectively. The root-knot nematode biological control bacterial agent of the invention has the characteristics of low cost, high control effect, no residue, and safety to humans and animals, and is a high-efficiency biological pesticide for preventing and treating root-knot nematode.

The invention provides a degrading bacterium for eliminating plant fungicide residues and application thereof, the degrading bacterium is identified as Providencia rettgeri Providencia retgeri , belonging to Gram-negative bacteria, which was deposited in the General Microorganism Center (CGMCC) of China Microbiological Culture Collection Management Committee (CGMCC) on May 15, 2017, and the preservation number is: CGMCC NO.14163. As the only carbon source and energy source for growth, the degradation rate of 100 mg / L eubacazole within 96 hours can reach more than 90%. The direct application of degrading bacteria can significantly reduce the field phylloxazole residue, which can effectively eliminate pollution and solve the problem of It solves the problem of excessive phyllazole residues in agricultural production, and produces green agricultural products that are non-toxic and pollution-free.

The invention relates to a microbe composite bacterial liquid comprising live bacteria of clostridium thermopalmarium, clostridium thermosuccinogenes, brevibacillus borstelensis, paenibacillus barengoltzii, bacillus subtilis, pseudomonas mendocina, and providencia rettgeri. The invention also provides a bacterial preparation prepared by using the composite bacterial liquid. The bacterial preparation is used for preparing an organic fertilizer. According to the invention, with the composite microbe bacterial liquid, during a composite fertilizer utilization process, the dosage of inorganic composite fertilizer can be reduced, such that production cost can be reduced. Also, with a synergetic effect provided by the microbe bacterial preparation, when dosages of nitrogen, phosphorous and potassium in organic-inorganic composite fertilizers are low, agricultural and forestry waste stalks with low prices and rich organic substances such as nitrogen, phosphorous, potassium and calcium are converted into micro-molecular substances such as monosaccharide and oligosaccharide which can be utilized by plants. Therefore, a relatively high crop yield is obtained, and a substantial yield increasing effect is provided. Agriculture in our nation has a severe dependence on chemical fertilizers. With the composite bacterial liquid provided by the invention, the situation can be changed, and agricultural ecological protection can be enhanced.

The invention discloses a Providencia rettgeri strain and application thereof. The Providencia rettgeri YL is collected in China General Microbiological Culture Collection Center (CGMCC) on April 28th, 2013, and the collection number is CGMCC No.7544. The Providencia rettgeri is used for treating nitrogenous organic wastewater, and can effectively remove organic nitrogen, ammonia nitrogen, nitrite nitrogen and nitrate nitrogen while removing organic carbon, and thus, the whole organic carbon and nitrogen synchronous removing process can be implemented only by one aerobic stage. The strain has the heterotrophic nitrification-aerobic denitrification function, can synchronously remove the organic carbon and nitrogen under aerobic conditions, can greatly reduce the occupied area and construction investment, can shorten the system start-up time, reduces the treatment cost, and enhances the treatment efficiency.
