Specific micropollutant biotransformation pattern by the comammox bacterium Nitrospira inopinata

The recently discovered complete ammonia-oxidizing (comammox) bacteria are occurring in various environments, including wastewater treatment plants. To better understand their role in micropollutant biotransformation in comparison with ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA), we investigated the biotransformation capability of Nitrospira inopinata (the only comammox isolate) for 17 micropollutants. Asulam, fenhexamid, mianserin, and ranitidine, were biotransformed by N. inopinata, Nitrososphaera gargensis (AOA) and Nitrosomonas nitrosa Nm90 (AOB). More distinctively, carbendazim, a benzimidazole fungicide, was exclusively biotransformed by N. inopinata. The biotransformation of carbendazim only occurred when N. inopinata was supplied with ammonia but not nitrite as the energy source. The exclusive biotransformation of carbendazim by N. inopinata was likely enabled by an enhanced substrate promiscuity of its unique AMO and its much higher substrate (for ammonia) affinity compared with the other two ammonia oxidizers. One major plausible transformation product (TP) of carbendazim is a hydroxylated form at the aromatic ring, which is consistent with the function of AMO. This TP was further transformed, and smaller linear TP candidates were identified. These findings provide fundamental knowledge on the micropollutant degradation potential of a comammox bacterium, to better understand the fate of micropollutants in nitrifying environments.
