Quantitative analysis of amino acid excretion by Methanothermobacter marburgensis under N₂-fixing conditions.

ABSTRACT: Methanogenic archaea (methanogens) possess fascinating metabolic characteristics, such as the ability to fix molecular nitrogen (N₂). Methanogens are of biotechnological importance due to the ability to produce methane (CH₄) from molecular hydrogen (H₂) and carbon dioxide (CO₂) and to excrete proteinogenic amino acids. This study focuses on analyzing the link between biological methanogenesis and amino acid excretion under N₂-fixing conditions. Among five hydrogenotrophic, autotrophic methanogens, Methanothermobacter marburgensis was prioritized and further cultivated in closed batch cultivation mode under N₂-fixing conditions. M. marburgensis was grown on chemically defined minimal medium with different concentrations of am
