METHOD FOR ENRICHMENT CULTURE OF AMMONIA-OXIDIZING ARCHAEA THROUGH CO-CULTURING WITH SULFUR-OXIDIZING BACTERIA

摘要

PURPOSE: A method for enrichment culture of ammonia-oxidizing archaea and a novel ammonia-oxidizing archaea SJ strain(KCTC 11878BP) are provided to easily obtain archaea resource and to study the characteristic and function of the archaea.;CONSTITUTION: A method for enrichment culture of ammonia-oxidizing archaea comprises a step of co-culturing the archaea with sulfur-oxidizing bacteria in a medium containing 0.1-8.0 mM of ammonium. A sulfur compound is used as a substrate for sulfur-oxidizing bacteria. The sulfur compound is 0.1-5.0 mM of sulfide, thiosulfate, polythionate, elemental sulfur, or sulfite. A composition for purifying ammonia-polluted marine environment contains ammoniz-oxidizing archaea SJ strain(deposit number: KCTC 11878BP) as an active ingredient.;COPYRIGHT KIPO 2013
