Proteobacteria became the predominant phylum in the denitrifying anaerobic methane oxidation system of goat rumen fluid. Pseudomonas aeruginosa NWAFUP1 individually perform the whole denitrifying anaerobic methane oxidizing process. P . aeruginosa NWAFUP1 supplementation reduced methane emissions and alleviated the nitrite accumulation and propionic acid synthesis inhibition induced by nitrate supplementation.
