The response of anaerobic ammonium oxidation (anammox) process and granular sludge in the upflow anaerobic sludge blanket reactor was analyzed under long-term exposure to MnO nanoparticles (NPs) (1-200 mg L). The addition of 200 mg L MnO NPs had a significantly positive effect on nitrogen removal and this system exhibited excellent performance, with a total nitrogen removal efficiency of 93.1%. Moreover, the specific anammox activity enhanced with increasing concentrations of MnO NPs up to the maximum value of 657.3 ± 9.3 mg TN g VSS d under MnO NPs concentration of 200 mg L. This value was approximately 1.6-fold higher than that of the reactor in the absence of MnO NPs. The extracellular polymeric substances and settling velocity were both increased with MnO NPs addition. Meanwhile, the high-throughput sequencing results revealed that MnO NPs increased the relative abundance of dominant bacteria (Candidatus Kuenenia) from 17.3% at the absence of MnO NPs to 23.9% at 200 mg L MnO NPs, which resulted in a higher efficiency of biological nitrogen removal on the anammox system. These results indicated that MnO NPs enhanced nitrogen removal performance of anammox process.

Nanoparticles produced from metals whose uses include biosensors, optics, and catalysts. In biomedical applications the particles frequently involve the noble metals, especially gold and silver.
A layer of protein coating adsorbed by NANOPARTICLES upon entry into PLASMA or other protein-containing biological fluids, which affects how nanoparticles are internalized by cells and cleared from the body.
White blood cells. These include granular leukocytes (BASOPHILS; EOSINOPHILS; and NEUTROPHILS) as well as non-granular leukocytes (LYMPHOCYTES and MONOCYTES).
The collective designation of three organizations with common membership: the European Economic Community (Common Market), the European Coal and Steel Community, and the European Atomic Energy Community (Euratom). It was known as the European Community until 1994. It is primarily an economic union with the principal objectives of free movement of goods, capital, and labor. Professional services, social, medical and paramedical, are subsumed under labor. The constituent countries are Austria, Belgium, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, Netherlands, Portugal, Spain, Sweden, and the United Kingdom.
