Abstract excerpt
The thermophilic hydrogenotrophic methanogen Methanothermobacter sp. CaT2 aggregates by itself. CaT2 is known to have a surface sugar layer and extracellular proteins that may be related to its aggregation. Aggregation-enhanced mutants, CHA001 and CHA002, were isolated after repeated cultivation for more than two years. When treated with proteinase K, CHA001 and CaT2 similarly exhibited a very low degree of...
