From: The antimethanogenic efficacy and fate of bromoform and its transformation products in rumen fluid

Methane production during incubation of 80 ml of rumen fluid (Exp 4). The treatments were: live rumen fluid with no addition (B-); live rumen fluid with A. taxiformis, equivalent to 2.4 µM CHBr3 added (B + A.tax); bromoform addition resulting in an initial concentration of 3 µM (B + CHBr3); and control treatments of autoclaved rumen fluid to which similar levels of bromoform (AC + CHBr3) and A. taxiformis (AC + A.tax) were added.
