Long-term preservation of anammox bacteria
Web摘要: Stable suppression of nitrite-oxidizing bacteria (NOB) is still a major challenge for the implementation of partial nitritation and anammox (PN/A) in mainstream treatment. Despite numerous suppression strategies demonstrated, it is increasingly recognized that NOB could develop resistance to these strategies, threatening the long-term stability of the … Web17 de mai. de 2011 · This is the first report of the successful reactivation of anammox biomass preserved via sub-zero freezing and/or lyophilization, and could be beneficial …
