•Amino acids were decomposed evidently by THP at 120 °C (8.9%) and 160 °C (26.7%).•Amino acids degradation in AD was promoted largely via decomposition during THP.•Varied THP temperature changed dominating bacteria utilizing amino acids in AD.•120 °C played little role in promoting amino acids metab...
