Summary: The PN/A process is a viable technology for nitrogen removal from wastewaters with high concentrations of ammonia, but its application in processing slaughterhouse byproducts wastewater has not been assessed. An increase in nitrogen loading rate did not significantly affect the removal efficiency of total nitrogen. Presence of organic matter promoted the growth of heterotrophic denitrifying bacteria while impairing the growth of Anammox bacteria.

Summary: Increased mariculture activities globally have led to elevated nitrogen compound levels and intensified accumulation of antibiotics. The study focused on the impact of sulfamethoxazole (SMX) on nitrate removal in mariculture wastewater. It was found that nitrification was not inhibited by SMX, but aerobic denitrification was. Proteobacteria, particularly Comamonas, Acinetobacter, and Thauera, were efficient in COD removal and SMX degradation.

Summary: Pisolithus sp. 1 is an ectomycorrhizal fungus with a strong Cr(VI) tolerance and reduction ability. This study investigated its physiological mechanism and relationship between Cr(VI) reduction and denitrification. The results showed that Cr(VI) induced elevated nitrate reductase activity and NO production in the mycelia, which was inhibited by NR inhibitor. NO was generated via NR-regulated denitrification. The study also found that P sp. 1 can secrete substances to combine with Cr(III) in a culture system.

Summary: This study investigates the dual effect of nitrate on AGS granulation and finds that nitrate feeding can initially promote granulation, but it inhibits granulation in the long-term. The study also provides evidence for the role of microbial factors related to denitrification and EPS production in the dual effect of nitrate. This research highlights the potential effects of nitrate on aerobic granulation, providing references for its utilization in nitrate-containing wastewater.

Summary: In this study, a strain called Psychrobacter cryohalolentis F5-6 was isolated and found to have a high aerobic-denitrifying rate at low temperatures. It has a high percentage of unsaturated fatty acids and short chain saturated acids. The strain prefers acetate as the carbon source for denitrification. The study also showed the nitrate metabolism processes of the strain and determined the optimal conditions for denitrification. This research provides valuable information and a potential bacterial resource for improving nitrate removal from low C/N water at low temperatures.

Summary: This study investigated the effects of different carbon sources on the treatment of nitrate-containing wastewater. The results showed that a system using citric acid as the carbon source had stronger denitrification ability and a more stable microbial population, resulting in better removal of nitrate nitrogen.

Summary: The Pseudomonas sp. G16 isolated from the aerobic pond of the farm was capable of heterotrophic nitrification and aerobic denitrification. It exhibited high removal rates of ammonia, nitrate, and nitrite, and had independent nitrification-denitrification ability with no nitrite accumulation. When immobilized as biochar-based particles, the strain G16 showed improved nitrogen removal efficiency and stability. Therefore, the application of strain G16 in real wastewater treatment has significant research value.

Summary: This study utilized sediment microbial fuel cells for denitrification in low-organic matter wastewater, achieving significant removal of nitrate. The denitrification process was driven by generated electrons and COD as the driving force. After the electrons were generated, denitrification efficiencies were effectively enhanced. Additionally, the removal efficiencies were positively correlated with external current intensities.

Summary: In this study, a halophilic strain SND-01 capable of aerobic-heterotrophic nitrogen removal (AHNR) was isolated from saltern sediment. The strain exhibited high efficiency in removing ammonium, nitrite, and nitrate from high-salinity wastewater. Various functional genes related to N metabolism were found in the strain's genome, establishing a complex AHNR pathway. The strain showed high adaptability under different conditions, making it suitable for treating saline wastewater with different N compositions.

Summary: In this study, a laboratory-scale aerobic bioreactor was designed to investigate the effect of tetracycline on simultaneous removal of different pollutants in mariculture wastewater. The results showed that tetracycline inhibited the activity of denitrifiers, but at a certain concentration, it promoted its degradation. The findings demonstrated that heterotrophic aerobic denitrification is an effective technology for treating nitrogen, COD, and antibiotics in mariculture wastewater.

Summary: This study highlights the importance of understanding how printing parameters impact the quality of printed parts in Binder Jet Additive Manufacturing (BJAM). It shows that successful layer formation favors larger droplet spacing when printing layers. Additionally, variations in key printing parameters such as droplet inter-arrival time have a negligible impact on surface roughness and saturation under the conditions tested.

Summary: In this study, a high efficient denitrifying bacterium Y23 was isolated from production brine of an oilfield. Y23 showed good sedimentation and immobilization properties and exhibited excellent denitrification performance under high dissolved oxygen concentration. Augmentation of Y23 in a reactor enhanced the removal efficiencies of nitrogen and chemical oxygen demand.

Summary: The study compared different scenarios of wastewater treatment to achieve resource recovery, showing that urine and blackwater separation are more effective options with significant reduction in greenhouse gas emissions. Greywater separation, while slightly less effective in mitigating climate change impact, needs attention to energy consumption.
