    烴降解菌的紫外誘變育種研究
    摘要
    近年來,石油污染日益嚴(yán)重,如何修復(fù)被污染的土壤及其修復(fù)技術(shù)的研究日益成為大家矚目的焦點(diǎn).而高效烴降解菌的篩選是其中的大熱門之一.本文通過對實(shí)驗(yàn)室保藏的5種石油降解菌(Z1、Z41、Z49、Y5、Y17)的初步篩選,選出石油降解效率比較高的菌種,然后為了進(jìn)一步提高該菌株的石油降解效率,對其進(jìn)行紫外誘變育種,誘變時間分為5S,15S,30S,40S,60S,再通過血平板初篩和搖床復(fù)篩,挑選出降解效率高的菌株,最終獲得的菌株降解率為★,與之前對照提高了★,篩選出石油降解能力比較好的菌株,以期給對石油土壤修復(fù)的研究做參考.

    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.
