12600379-3	2003	HPr was then fully degraded to methane and carbon dioxide via acetate.	Methane	31-38	haptoglobin-related protein	Homo sapiens	0-3	
29073521-3	2018	Methanogens can consume H2 to produce CH4 in MECs, which has led to a drop of H2 production efficiency, H2 production rate (HPR) and also a low percentage of H2 in the produced biogas.	Methane	38-41	haptoglobin-related protein	Homo sapiens	104-122	
35358877-3	2022	The HPr/HAc ratios of 0.5 and 1.5 maintained efficient syntrophy among electroactive bacteria, hydrogenotrophic methanogens, and homoacetogens, leading to higher methane yields.	Methane	162-169	haptoglobin-related protein	Homo sapiens	4-7	
29161570-3	2018	The results demonstrated that after long term of acclimation to low pH, the digester could produce methane from propionate at pH 4.8-5.5 with 0.3-0.4 L g-1 propionic acid (HPr) d-1 of the volatile solids (VS) methane production.	Methane	99-106	haptoglobin-related protein	Homo sapiens	172-175
