Abstract

The invention provides a petroleum hydrocarbon degradation bacterium and a culturing, screening and applying method thereof, and relates to a marine petroleum hydrocarbon degradation bacterium. The petroleum hydrocarbon degradation strain is Martelella mediterranea( Martelella mediterranea ) MM-45, the Martelella mediterranea is a bacterial strain belonging to Martelella, showing negative of Gram's staining, the biological characteristics are a non-fermentation type, the Martelella mediterranea is obligate aerobic, the shape of the strain is non spore bearing, colonies are in the shape of a circle, yellow and opaque, the surface is smooth and moistening, the edges are regular, haloes do not exist, centers are in protrusion and the diameter is 2-3mm. The petroleum hydrocarbon degradation bacterium can be applied to degradation organic compounds. Through identification, the 16S rDNA gene order of the Martelella mediterranea is a type strain Martelella mediterranea DSM 17316, and the similarity is 99.61%.

Description

technical field

[0001] The invention relates to marine petroleum hydrocarbon degrading bacteria, in particular to a strain of petroleum hydrocarbon degrading bacteria and its cultivation, screening and application. Background technique

[0002] Because crude oil contains unstable hydrocarbons, including polycyclic aromatic hydrocarbons, toluene, ethylbenzene and xylene, these harmful substances can enter the blood vessels of the human body through breathing, skin absorption and eyeballs, which can cause nausea, headache, dizziness, etc. Uncomfortable feeling, even cancer, so this oil spill is a great threat to the health of nearby residents. Oil spill pollution accidents will also cause severe hypoxia in large areas of the sea, destroy marine productivity, cause a large number of fish, shrimp, shellfish and seabirds to die, and cause local "ocean desertification"; Cause deserted beaches, destroy mariculture and salt pan production, pollute or destroy coastal tourist areas, ...
