Ammonia stress on nitrogen metabolism in tolerant aquatic plant— Myriophyllum aquaticum

Ecotoxicology and Environmental Safety, 2017
Ammonia has been a major reason of macrophyte decline in the water environment, and ammonium ion toxicity should be seen as universal, even in species frequently labeled as "NH4+ specialists". To study the effects of high NH4+-N stress of ammonium ion nitrogen on tolerant submerged macrophytes and investigate the pathways of nitrogen assimilation in ...

Characterization of a novel ADP-ribosylation factor gene from Macrobrachium nipponense and its response to ammonia nitrogen stress [PDF]

Aquaculture Environment Interactions, 2021
ADP-ribosylation factors (Arfs) are guanosine triphosphate (GTP)-binding proteins that play essential roles in membrane trafficking, and they have been recently reported to be involved in innate immunity in crustaceans.

Fasting influences the muscle quality of fish during transportation by regulating the balance between energy metabolism and ammonia nitrogen stress. [PDF]

J Adv Res
Fasting has been widely applied in aquaculture to improve the welfare of fish. However, fasting regulate the interplay of energy metabolism and ammonia nitrogen stress on the muscle quality unclear.To clarify the impact of fasting on the energy metabolism, ammonia nitrogen stress, and muscle quality.Blunt snout bream (Megalobrama amblycephala) were ...

UPR-mediated apoptosis induced by ammonia nitrogen stress is contributed to gills damage in Litopenaeus vannamei

Aquaculture Reports
Ammonia nitrogen concentration is a critical factor affecting shrimp health in aquaculture, with the gills being the main target organ of ammonia nitrogen toxicity. This study investigated the role of unfolded protein response (UPR)-mediated apoptosis in

Nitrification upon Nitrogen Starvation and Recovery: Effect of Stress Period, Substrate Concentration and pH on Ammonia Oxidizers’ Performance

Fermentation, 2022
Nitrification has been widely applied in wastewater treatment, however gaining more insight into the nitrifiers’ physiology and stress response is necessary for the optimization of nutrient removal and design of advanced processes.

Robust ammonia oxidation by “Candidatus Nitrosacidococcus tergens” across a broad pH range [PDF]

mBio
Acidophilic ammonia-oxidizing bacteria (AOB) have only recently been discovered. These organisms hold great promise for acidic wastewater treatment; however, their physiology remains poorly understood compared to that of neutrophilic AOB.

Oxidative Stress Can Be Attenuated by 4-PBA Caused by High-Fat or Ammonia Nitrogen in Cultured Spotted Seabass: The Mechanism Is Related to Endoplasmic Reticulum Stress

Antioxidants, 2022
Oxidative stress is a common phenomenon in aquaculture, which can be induced by nutritional or environmental factors. Generally, oxidative stress causes poor growth performance, metabolic dysregulation, and even the death of aquatic animals. To identify a nutritional intervention strategy, high-fat diet (HFD) feeding (Experiment I) and acute ammonia ...

Physiological and transcriptomic analysis of the tetraploid Pacific oyster (Crassostrea gigas) under acute ammonia nitrogen stress

Aquaculture Reports
In recent years, high-density oyster farming has led to the deterioration of the environment in the cultured sea area, especially in the high-temperature summer, the decomposition and death of organic organisms and their excreta will lead to the increase
