79.微生物によるキノリンの分解

抄録

For the purpose of removing nitrogen atoms from heavy oil by microbial procedures, the first approach was made to obtain microorganisms capable of degrading quinoline by enrichment culture. The degradation of quinoline by the chosen isolate yielded initially 2-hydroxyquinoline and then 8-hydroxycoumarin. This strain was able to degrade quinoline and a few methylquinolines in a complex basic fraction of coal-liquid. Isolation of mutant bacteria which tolerate fairly high concentration of quinoline is in progress.
