Dissimilatory metal reduction by the facultative anaerobe Pantoea agglomerans SP1.
Anaerobic enrichments with acetate as the electron donor and Fe(III) as the terminal electron acceptor were obtained from sediments of Salt Pond, a coastal marine basin near Woods Hole, Mass. A pure culture of a facultatively anaerobic Fe(III) reducer was isolated, and 16S rRNA analysis demonstrated that this organism was most closely related to Pantoea (formerly Enterobacter) agglomerans, a me...
متن کاملDissimilatory metal reduction.
Microorganisms can enzymatically reduce a variety of metals in metabolic processes that are not related to metal assimilation. Some microorganisms can conserve energy to support growth by coupling the oxidation of simple organic acids and alcohols, H2, or aromatic compounds to the reduction of Fe(III) or Mn(IV). This dissimilatory Fe(III) and Mn(IV) reduction influences the organic as well as t...
متن کاملThe nitrogenase from the facultative anaerobe
The effects of MgADP and MgATP on the kinetics of a pre-steady-state electron-transfer reaction and on the steady-state kinetics of H2 evolution for nitrogenase proteins of K. pneumoniae were studied. MgADP was a competitive inhibitor ofMgATP in the MgATPinduced electron transfer from the Fe-protein to the Mo-Fe-protein. A dissociation constant K' = 20,UM was determined for MgADP. The release o...
متن کاملGrowth of the facultative anaerobe Shewanella putrefaciens by elemental sulfur reduction.
The growth of bacteria by dissimilatory elemental sulfur reduction is generally associated with obligate anaerobes and thermophiles in particular. Here we describe the sulfur-dependent growth of the facultatively anaerobic mesophile Shewanella putrefaciens. Six of nine representative S. putrefaciens isolates from a variety of environments proved able to grow by sulfur reduction, and strain MR-1...
