Abstract

The sensitivity of the requirement of Methanobacterium ruminantium strain M1 to a new coenzyme, 2-mercaptoethanesulfonic acid (HS-CoM) was examined by use of new techniques that were developed for rapid and efficient handling of large numbers of cultures of methanogenic bacteria. The system uses sealed tubes that contain a gas mixture of 80% hydrogen and 20% carbon dioxide under a pressure of 2 to 3 atm. This modification of the Hungate technique reduces variability among replicate cultures and simplifies the dispensing, sterilization, and storage of liquid media as well as the transfer and maintenance of methanogenic bacteria. Results indicate a limit of sensitivity of the assay at 5 nM HS-CoM, with half-maximal growth at 25 nM HS-CoM. Coenzyme activity could be replaced by 2,2'-dithiodiethanesulfonic acid at a half-molar equivalent of the HS-CoM concentration, or by 2-(methylthio)ethanesulfonic acid on an equimolar basis. These data reveal a very sensitive and precise requirement for HS-CoM in the nutrition of this fastidious anaerobe.

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.
