Production of dimethyl triselenide and dimethyl diselenenyl sulfide in the headspace of metalloid-resistant Bacillus species grown in the presence of selenium oxyanions
Open accessAbstract
A Bacillus species harvested from the environment is metalloid resistant and, when grown anaerobically in complex growth medium and amended with the selenium oxyanion selenate, selenite, or selenocyanate, produces volatile organoselenium compounds in bacterial culture headspace. Two novel compounds so far undetected in bacterial culture headspace, CH3Se2SCH3 and CH3SeSeSeCH3, are produced and can be detected using solid-phase microextraction and gas chromatography with either fluorine-induced chemiluminescence or mass spectrometric detection. Differences in the electron impact fragmentation pattern of the mixed sulfur/selenide compounds allow the tentative differentiation between the symmetric and asymmetric isomers in this bacterium's headspace in favor of the asymmetric CH3SeSeSCH3 isomer.

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.
