The alleviative effect of exogenous phytohormones on the growth, physiology and gene expression of Tetraselmis cordiformis under high ammonia-nitrogen stress

Bioresource Technology, 2019
In this study, the toxic effect of high ammonia on microalgae Tetraselmis cordiformis and the detoxification of phytohormones were researched. The growth, physiological changes, and gene transcription of T. cordiformis were examined. Malondialdehyde content was increased by 2.12 times compared with the control, suggesting the oxidative damage of T ...

Organ-specific responses to total ammonia nitrogen stress on juvenile grass carp (Ctenopharyngodon idellus)

Environmental Science and Pollution Research, 2019
Fish are important in constructed wetland (CW) ecosystem. An 80-day experiment was conducted by exposing juvenile grass carp (Ctenopharyngodon idellus) to 0, 0.5, 2.0, 4.5, 9.0, and 18.0 mg L-1 total ammonia nitrogen (TAN) stress to determine the severity of physiological changes in fish organs (liver, gills, and muscle) in CW.

C-type lectin response to bacterial infection and ammonia nitrogen stress in tiger shrimp (Penaeus monodon)

Fish & Shellfish Immunology, 2019
C-type lectins (CTLs) are pattern recognition receptors (PRRs) that are important in invertebrate innate immunity for the recognition and elimination of pathogens. Although they were reported in many shrimp, C-type lectins subfamily contain a large number of members with different functions that need to research in deep.

Bacillus velezensis LG37 protects Macrobrachium rosenbergii from ammonia nitrogen stress

Microbial Pathogenesis
This study evaluated the protective effects of Bacillus velezensis LG37 on Macrobrachium rosenbergii under ammonia nitrogen stress, with a focus on survival, antioxidant capacity, and immune response. Juvenile prawns were divided into two groups: a control group without LG37 (Group A) and a treatment group with dietary LG37 supplementation (Group B ...
