  • Composition of biologically pure cultures of Alcaligenes denitrificans denitrificans and a porous carrier useful for biodegradation
    Patent number: 5169777
    Abstract: The present invention is a process of degrading 1,4-dibenz-oxazepine with a icroorganism enzymatically capable of converting the 1,4-dibenz-oxazepine into at least o-nitrophenol which is further converted to catechol. The present invention is preferably carried out using a strain of Alcaligenes denitrificans denitrificans. Additional related compounds which can be degraded with Alcaligenes denitrificans denitrificans include: o-nitrophenol, catechol, and 3-methylcatechol.
    Type: Grant
    Filed: August 27, 1990
    Date of Patent: December 8, 1992
    Assignee: The United States of America as represented by the Secretary of the Army
    Inventors: Mark V. Haley, Wayne G. Landis
