Özet

The anaerobic ammonium oxidation (anammox) process is a promising biological wastewater treatment technology in order to remove pollutant ammonia from wastewater. One of the most intriguing and unique features of the anammox bacteria is the utilization of hydrazine as an intermediate in their metabolisms. Today, hydrazine has been used in several industries from pharmaceuticals to space. Although hydrazine is an extremely toxic chemical, global demand for hydrazine has expanded day by day. Such that, the worldwide value of the hydrazine market has been foreseen to reach $806.09 million by 2030. Moreover, hydrazine has only been produced by chemical processes at present, which brings many disadvantages. Considering all, the main question is: "Can hydrazine be biosynthesized by anammox bacteria for industrial purposes together with reducing environmental pollution coordinately?". Within this scope, current research aims to investigate the response and tolerance of the enriched anammox culture against gradually increased hydrazine concentrations in a long-term manner. Results have indicated that bioaccumulated hydrazine in the anammox metabolism might be increased with the appropriate experimental strategy.
