Chemotaxis in Methanospirillum hungatei.
Methanospirillum hungatei gave a positive chemotactic response to acetate.
متن کاملKinetics of Formate Metabolism in Methanobacterium formicicum and Methanospirillum hungatei.
The kinetics of formate metabolism in Methanobacterium formicicum and Methanospirillum hungatei were studied with log-phase formate-grown cultures. The progress of formate degradation was followed by the formyltetrahydrofolate synthetase assay for formate and fitted to the integrated form of the Michaelis-Menten equation. The K(m) and V(max) values for Methanobacterium formicicum were 0.58 mM f...
متن کاملNovel complex polar lipids from the methanogenic archaebacterium Methanospirillum hungatei.
The methanogenic archaebacterium Methanospirillum hungatei contains two unusual phosphoglycolipids that account for 64 percent of the total cellular lipids. These lipids are derivatives of the dibiphytanyl diglycerol tetraether, previously identified in methanogens. One of the free hydroxyls of this tetraether is esterified with glycerophosphoric acid, and the other is linked glycosidically to ...
متن کاملComplete genome sequence of Methanospirillum hungatei type strain JF1
Methanospirillum hungatei strain JF1 (DSM 864) is a methane-producing archaeon and is the type species of the genus Methanospirillum, which belongs to the family Methanospirillaceae within the order Methanomicrobiales. Its genome was selected for sequencing due to its ability to utilize hydrogen and carbon dioxide and/or formate as a sole source of energy. Ecologically, M. hungatei functions as...
متن کاملPathway of propionate oxidation by a syntrophic culture of Smithella propionica and Methanospirillum hungatei.
The pathway of propionate conversion in a syntrophic coculture of Smithella propionica and Methanospirillum hungatei JF1 was investigated by (13)C-NMR spectroscopy. Cocultures produced acetate and butyrate from propionate. [3-(13)C]propionate was converted to [2-(13)C]acetate, with no [1-(13)C]acetate formed. Butyrate from [3-(13)C]propionate was labeled at the C2 and C4 positions in a ratio of...
