A previous study showed that ammonia oxidation by the Thaumarchaeota Nitrosopumilus maritimus (group 1.1a) was resistant
to concentrations of the C₈ 1-alkyne, octyne, which completely inhibits activity by ammonia-oxidizing bacteria. In this study, the
inhibitory effects of octyne and other C₂ to C₁₀ 1-alkynes were evaluated on the nitrite production...
