Carbon-Nitrogen Cycling Through Microbial Formamide Metabolism

ROBERT C. THATCHER 1 and TERRY L. WEAVER 1

1 Laboratory of Microbiology, Cornell University, Ithaca, New York 14853

A microbially mediated carbon-nitrogen cycle involving a newly isolated facultatively methylotrophic pseudomonad is described. The new isolate utilizes formamide as its sole carbon, nitrogen, and energy source. Other organisms involved in the proposed cycle are cyanogenic plants; phytopathogenic fungi, which convert cyanogenic glycosides to formamide; and nitrifying microorganisms. This cycle may be quantitatively important in view of the large variety of cyanogenic plants known to exist.
