The invention discloses an azoxystrobin-degrading bacterium as well as the bacterium agent produced therefrom and application thereof. The strain is Ochrobactrum anthropi SH14, which was deposited in China Center for Type Culture Collection (CCTCC) on December 20, 2013, and the preservation number is CCTCC NO: M 2013681. The strain can effectively degrade azoxystrobin pesticide residues in a short period of time, and can be used to restore natural environments such as water bodies and soils polluted by azoxystrobin. The preparation prepared by the bacterial strain has the advantages of low production cost, convenient use, good removal effect and the like. The use of this bacterial agent can reduce the residual amount of azoxystrobin in water and soil by more than 85% in a short period of time, effectively repair the natural environment polluted by azoxystrobin, solve the problem of excessive pesticide residues and environmental pollution in agricultural production, and protect the ecology environment and human health.

The invention discloses an EPSP synthase gene derived from ochrobactrum anthropi and application thereof. The EPSP synthase gene contains 1353 basic groups and 451 coded amino acids, the nucleotide sequence of the EPSP synthase gene is as shown in SEQ ID NO1, and the amino acid sequence of the coded proteins is as shown in SEQ ID NO2. The EPSP synthase gene derived from ochrobactrum anthropi disclosed by the invention is synthesized by a manual method, has high homology with the reported EPSP synthase gene derived from agrobacterium tumfaciens, has higher glyphosate tolerance, and can be usedfor culturing genetically modified crops.

The invention relates to a composite microbial preparation of linear alkyl benzene sulphonic acid as well as a preparation method and application thereof. The composite microbial preparation of the linear alkyl benzene sulphonic acid contains Bacillus subtilis, Ochrobactrum anthropi and pseudomonas aeruginosa; the microbial content of the Bacillus subtilis accounts for 15-35% that of the total microbial content; the microbial content of the Ochrobactrum anthropi accounts for 40-60% that of the total microbial content; and the microbial content of the pseudomonas aeruginosa accounts for 10-30% that of the total microbial content. The composite microbial preparation has the advantages that the linear alkyl benzene sulphonic acid can be rapidly decomposed and thoroughly oxidized into CO2 and H2O, so that the growth of harmful microbe is effectively suppressed, the biological treatment efficiency of LAS (Sodium Dodecyl Benzene Sulfonate) wastewater is greatly increased, and the odor of sewage is eliminated.

The invention discloses an ochrobactrum anthropi M11 for degrading unsymmetrical dimethylhydrazine and a method for degrading the unsymmetrical dimethylhydrazine by using the ochrobactrum anthropi M11. The method comprises the steps of: inoculating a strain of the ochrobactrum anthropi M11 to a slant culture medium, and culturing to obtain a slant culture product; inoculating the slant culture product into a container in which a seed culture medium is arranged, and culturing to obtain a seed liquid; immobilizing the seed liquid to obtain immobilized mycelial pellets; and inoculating the immobilized mycelial pellets into a container in which a substrate solution is filled according to an inoculation amount of 10-30%, mixing, and degrading for 72 hours at a temperature of 30-37 DEG C and the oscillation rate of 120-200r / min, wherein the inoculation amount is calculated based on the volume proportion of the seed liquid to the substrate solution. According to the invention, the degrading rate for the unsymmetrical dimethylhydrazine is high up to 97.7%.

The invention discloses a compound microbial active filling material for removing sulphur-containing repugnant substances, as well as preparation and application of the compound microbial active filling material. Ochrobactrum anthropi SL1 and aquamicrobium defluvii SU1 related in the invention are isolated bacteria obtained in a reactor for processing repugnant substances, such as H2S, in a water pollution control laboratory of the ecological environment research centre of the Chinese academy of sciences. The bacterial strains are preserved in the general microbial centre of the Chinese general microbial strain preservation and management committee. The preservation numbers are CGMCC No.7400 and CGMCC No.7399 respectively. The compound microbial active filling material disclosed by the invention has the advantages of being large in specific area, high in porosity, good in air permeability, low in resistance, high in bacterial cell loading capacity and less prone to run away; and because of being loaded with ochrobactrum anthropi SL1 and aquamicrobium defluvii SU1, the compound microbial active filling material is difficult to decay and deform in a bioreactor for purifying waste gas, and therefore, the compound microbial active filling material can be used for a long time and is applied to complex processing conditions.
