タイトル Isolation and characterization of a tetramethylammonium-degrading Methanococcoides strain and a novel glycine betaine-utilizing Methanolobus strain.
ジャーナル Arch Microbiol
Abstract Two novel strains of methanogens were isolated from an estuarine sediment with the capability to utilize quaternary amines. Based on the 16S rRNA analysis, strain B1d shared 99 % sequence identity with Methanolobus vulcani PL-12/M(T) and strain Q3c shared 99 % identity with Methanococcoides sp. PM1 and PM2, but our current isolates display clearly different capabilities of growth on quaternary amines and were isolated based on these capabilities. Strain Q3c was capable of growth on tetramethylammonium and choline, while strain B1d was capable of growth on glycine betaine. Ml. vulcani PL-12/M(T) was incapable of growth on glycine betaine, indicating an obvious distinction between strains B1d and PL-12/M(T). Strain Q3c now represents the only known tetramethylammonium-utilizing methanogen in isolation. Strain B1d is the first quaternary amine-utilizing methanogen from the genus Methanolobus. This study suggests that quaternary amines may serve as ready precursors of biological methane production in marine environments.
