Denitrification by Alcaligenes eutrophus is plasmid dependent

Denitrification by Alcaligenes eutrophus is plasmid dependent

D Römermann et al. J Bacteriol. 1985 May.

Abstract

Curing of the hydrogenase-specifying megaplasmid pHG indigenous to strains of the facultative lithoautotrophic bacterium Alcaligenes eutrophus was correlated with a loss of denitrifying ability (Nitd). The retransfer of plasmid pHG1 reconstituted the Nitd phenotype. Plasmid-free mutants were still capable of converting some nitrate to nitrite, but they did not metabolize nitrite under anaerobic conditions.
