Effect of Fluoroacetates on Methanogenesis in Samples from Selected Methanogenic Environments
Abstract
Trifluoroacetic acid (TFA) is an atmospheric decomposition product of a new generation of refrigerants that will replace current ozone-depleting CFCs. The effect of trifluoroacetic acid on microbial methanogenesis was assessed using environmental samples from four distinct methanogenic systems: the anaerobic digestor, the rumen, freshwater sediments, and marine sediments. TFA exhibited no toxcity, as evidenced by the rate of methanogenesis, at concentrations up to 10 mM. [1- 14 C]TFA was used to test for biodegradation (release of 14 CO 2 ) in methanogenic marine sediments. No significant release of 14 CO 2 was observed. As a control, the toxic monofluoroacetate (MFA), which is not an atmospheric degradation product of CFC replacements, was found to inhibit methanogenesis in freshwater and anaerobic digestor samples at or above concentrations of 0.1 mM. We conclude that TFA is inert in these methanogenic systems and there is no evident toxicity to either the methanogenic or fermentative populations.

“However, these results proved difficult to reproduce in methanogenic samples from different environments (100), and the microorganisms and enzymes responsible for reductive defluorination were not identified in the original studies.”

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.
