Water pollution has become increasingly serious, and the main pollutant in most water bodies is nitrogen. Microbial nitrification\/denitrification is one of the most effective nitrogen removal pathways for wastewater.<\/p>\n

General<\/a>ly, the traditional processes of microbial nitrogen removal include two parts: aerobic nitrification and anaerobic denitrification. Nitrification and denitrification can be carried out simultaneously in one reactor by a class of microorganisms\u2014heterotrophic nitrification-aerobic denitrification (HN-AD) bacteria.<\/p>\n

A research group led by Prof. Wu Jinshui from the Institute of Subtropical Agriculture (ISA) of the Chinese Academy of Science<\/a>s isolated a novel heterotrophic nitrification-aerobic denitrification bacterium\u2014Alcaligenes faecalis WT14, which has the potential to treat high-ammonium wastewater.<\/p>\n

The study was published in Journal of Environmental Management<\/i> on Jan. 16.<\/p>\n

The researchers found WT14 could tolerate high concentration ammonia nitrogen (NH4<\/sub>+<\/sup>-N) up to 2000 mg\u00b7L-1<\/sup> and had an efficient NH4<\/sub>+<\/sup>-N removal rate of 55.9 mg\u00b7L-1<\/sup>\u00b7h-1<\/sup>.<\/p>\n

Unlike other Alcaligenes faecalis species, WT14 could efficiently remove high concentration nitrate (NO3\u2014N) or nitrite (NO2\u2014N) when they are the sole nitrogen sources.<\/p>\n

These results implied that WT14 is a novel Alcaligenes faecalis strain and has the potential for treating wastewater containing high-strength NH4<\/sub>+<\/sup>-N, NO3<\/sub>\u2014N, or NO2<\/sub>\u2014N.<\/p>\n\n
