Hydrocarbon of degrading bacteria ultraviolet mutation breeding research
the
In recent years,oil pollution is serious,how to fix the contaminated soil and repair technology research increasingly become everyone's attention.And high efficiency degradation bacterium hydrocarbon screening is one of the big popular one.This article through to the laboratory of five preservation oil degradation bacterium (Z1,Z41,Z49,Y5,Y17) preliminary screening,choose oil is high efficiency degradation strains,and then in order to further improve the efficiency of the fungus oil degradation,and carry on the uv mutation breeding,induced time is divided into 5 S,15 S,30 S,40 S,60 S,again through the blood flat screen and wave at the beginning of the bed after screen,selected high efficiency degradation of the strain,the strain of eventually get degradation rate for u,and improve the control before u,and screened oil better strains degradation ability to repair the research on oil soil for reference.
