Abstract

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%.

Description

technical field

[0001] The invention relates to the field of biological technology, in particular to a Pallidum pallidum M11 degrading unsymmetrical dimethylhydrazine and a method for degrading unsymmetrical dimethylhydrazine. Background technique

[0002] Unsymmetrical dimethylhydrazine, the English name is Unsymmetrical Dimethylhydrazine, referred to as UDMH, and the molecular formula is (CH 3 ) 2 NNH 2 , has a strong irritating fishy odor, is flammable, volatile, colorless or slightly yellowish transparent liquid. The molecular weight of unsymmetrical dimethylhydrazine is 60.11, the boiling point is 63°C, the freezing point is -57.2°C, and the density is 0.791g / cm 3 , has good hydrophilicity, is miscible with water, and can be mixed with gasoline, alcohol and other organic solvents. Unsymmetrical dimethylhydrazine is reductive and can be slowly oxidized by air at room temperature.

[0003] As a propellant, unsymmetrical dimethylhydrazine has high calorific value, hig...
