Summary: This study investigated the response of a thermophilic denitrification system (50 degrees C) to a wide range of pH (3-11) and found that it could adapt to pH 5-11 but suffered from nitrite and ammonia accumulation at pH 3. The enrichment of specific functional thermophiles contributed to the tolerance towards unfavorable pH, and the selection advantage of nitrate reducing bacteria and the enrichment of DNRA bacteria were responsible for the nitrite and ammonia accumulation at pH 3. Functional gene prediction denoted higher narG/(nirK + nirS) and nrfA at pH 3, facilitating partial denitrification and DNRA.

Summary: This study investigated the nitrogen removal mechanisms during swine manure anaerobic digestion and the effects of biogas circulation and activated carbon addition. The methane yield was increased by 25.9%, 22.3%, and 44.1% with biogas circulation, activated carbon addition, and their combination, respectively. Nitrification-denitrification was found to be the dominant ammonia removal pathway in all digesters, while anammox did not occur. Biogas circulation promoted mass transfer and enriched nitrification and denitrification bacteria and functional genes, while activated carbon facilitated ammonia removal as an electron shuttle. The combined strategies significantly reduced total ammonia nitrogen by 23.6%.

Summary: The aim of this research was to investigate the metabolic relationship between nitrate removal and aerobic respiration in mixed bacterial consortia. The study found that aerobic respiration can stimulate nitrate transformation by facilitating nitrate uptake and generating NADH. It was also discovered that the highest total nitrogen removal rate was achieved in a reactor with moderate aeration intensity, where the intracellular levels of poly-beta-hydroxybutyrate (PHB) and NADH were highest.

Summary: The study demonstrated that sulfamethoxazole, chlortetracycline and amoxicillin have inhibitory effects on microbial denitrification performance, resulting in decreased nitrate removal efficiencies and decreased expression of important genes. Higher concentrations of antibiotics lead to stronger inhibitory effects, potentially causing changes in the abundance of denitrifying bacterial genera.

Summary: Soil microbes play a crucial role in biogeochemical processes in forest ecosystems. Soil pH is an important factor that positively affects these processes. However, our study found weak and/or curvilinear relationships between soil pH and microbial biomass and activity, suggesting that plant-microbial interactions and other complexities may inhibit or mask microbial response to changes in pH.
