Abstract

A U(VI) reduction-deficient mutant (Urr) screening technique was developed and combined with chemical mutagenesis procedures to identify a Urr mutant of Shewanella putrefaciens strain 200. The Urr mutant lacked the ability to grow anaerobically on U(VI) and NO(2)(-), yet retained the ability to grow anaerobically on eight other compounds as terminal electron acceptor. All 11 members of previously isolated sets of Fe(III) and Mn(IV) reduction-deficient mutants of S. putrefaciens 200 displayed Urr-positive phenotypes with the Urr screen and were capable of anaerobic growth on U(VI). This is the first reported isolation of a respiratory mutant that is unable to grow anaerobically on U(VI) as terminal electron acceptor.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Evidence was presented to suggest that the mechanism of U(VI) reduction by a S. putrefaciens strain was distinct from those of Fe(III) and Mn(IV) reduction, but may share components of the nitrite-reducing pathway.

    “Evidence was presented to suggest that the mech-anism of U(VI) reduction was distinct from those of Fe(III) and Mn(IV) reduction, but may share components of the nitrite-reducing pathway [123].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
