Oxidation of sulfide by Spartina alterniflora roots

Article Abstract:

Oxidation of sulfide by the roots of Spartina alterniflora, a dominant salt marsh grass, is discussed. Hydrogen sulfide is a common metabolic poison found in abundant amounts in marine-reducing environments. Sulfide blocks aerobic evaporation, but the roots of the marsh grass at their tips show substantial ability to catalyze sulfide oxidation, as seen from closed-chamber respirometry. A large part of the catalysis seems to be nonenzymatic and higher in roots from a high-sulfide site.
