A novel heterotrophic aerobic denitrifying Pseudomonas hunanensis strain DC-2 was screened from the sediments of Lake Dianchi and identified with high nitrification/denitrification ability. Within 30 h, removal efficiency ammonium-N nitrate-N could reach 98.8% 88.4%, respectively. The results single-factor experiments indicated that exhibited excellent denitrification ability under conditions using sodium citrate as nitrogen source, an initial pH 7, a C/N ratio 10, temperature °C. Nitrogen balance suggested this removed N mainly via assimilation. Moreover, pathway explored by genome enzymatic assays, complex metabolism established, including nitrification-aerobic (HN-AD), assimilatory reduction nitrate (ANRA), ammonia Additionally, immobilized into particles for denitrification, demonstrating efficacy in continuous total (84.8% TN). Hence, demonstrated significant potential treating real aquaculture wastewater.

Managing nitrogen and phosphorus pollution in high-salinity wastewater is a critical challenge for sustainable aquaculture environmental protection. In this study, novel salt-tolerant strain, Pseudomonas sediminis D4, was isolated from brackish water environment. This strain exhibited simultaneous heterotrophic nitrification–aerobic denitrification removal capabilities. Biosafety assays demonstrated that the antibiotic-sensitive safe aquatic environments. The optimal conditions phosphate of D4 were carbon/nitrogen (C/N) ratio 10, phosphorus/nitrogen (P/N) 0.2, pH 7, temperature 30 °C while using sodium succinate as carbon source. Under these conditions, achieved efficiencies 97.36% ammonia (NH4+-N), 100.00% nitrate (NO3−-N), 98.02% nitrite (NO2−-N), along with 94.69%, 89.56%, 97.40% PO43−P, respectively. strong salinity tolerance, functioning effectively within range 0% to 5% (w/v), maintaining high efficiency at 3%. Enzyme activity verified existence key enzymes, such oxidase, oxidoreductase, reductase, polyphosphate kinase, exopolyphosphatase, which are essential nitrification-aerobic capabilities D4. These findings highlight potential biological treatment wastewater.

Marimo is a type of microalgal-bacterial granular sludge (MBGS) that exists in natural water bodies. For the first time, this paper explored feasibility marimo real wastewater effluent polishing, focusing on nutrient removal as compared with MBGS. The results showed color gradually darkened during 21-day experiment, and chlorophyll content increased significantly. Although MBGS fairly similar performance terms NO3−-N TN, exhibited better phosphate to contained different algae but same bacterial phylum Proteobacteria, including denitrifiers. In addition, had higher relative abundance nitrite reductase than MBGS, suggesting denitrification process might also happen addition assimilation. This study expected initiate application for polishing reclamation, shedding light nature-based self-purification technology era carbon neutrality.
