The widespread application of nanotechnology inevitably leads to an increased release engineered nanoparticles (ENPs) into the environment. Due their specific physicochemical properties, ENPs may interact with other contaminants and exert combined effects on microbial community metabolism anaerobic digestion (AD), important process for organic waste reduction, stabilization, bioenergy recovery. However, complicated interactions between as well AD are often overlooked. This review therefore focuses co-occurrence cocontaminants in process. key influences summarized from available literature, including critical mechanisms influencing factors. Some sulfides, coagulants, chelating agents have a dramatic "detoxification" effect inhibition AD. some antibiotics surfactants increase reasons these differences be related interactive cocontaminants, changes enzyme activities, adenosine triphosphate (ATP) levels, reactive oxygen species (ROS) production, communities. New scientific opportunities better understanding coexistence real world situations converging scale nanoparticles.

Anaerobic digestion (AD) plays a significant role in renewable energy recovery. Upgrading AD from thermophilic (50–57 °C) to mesophilic (30–38 conditions enhance process stability and reduce input remains challenging due the high sensitivity of microbiomes temperature fluctuations. Here we compare effects two decreasing-temperature modes 55 35 °C on cell viability, microbial dynamics, interspecies interactions. A sharp transition (ST) is one-step by 20 d−1, while mild (MT) stepwise 1 d−1. We find greater decrease methane production with ST (88.8%) compared MT (38.9%) during period. mode overproduced reactive oxygen species 1.6-fold, increased membrane permeability 2.2-fold, downregulated metabolism 25.1%, leading apoptosis anaerobes 1.9-fold release intracellular substances 2.9-fold, further constraining methanogenesis. The higher (1.6 vs. 1.1 copies per gyrA) metabolic activity acetate-dependent methanogenesis implied more efficient steady mesophilic, MT-mediated system. Metagenomic binning network analyses indicated that induced dysbiosis keystone greatly enhanced functional redundancy, causing loss syntrophic interactions redundant pathways. In contrast, interconnections (average degrees 44.9 22.1) at state suggested could better maintain necessary system functionality through syntrophy or specialized Adopting transform digesters into feasible potentially optimization broader application practical anaerobic engineering.

High salinity inhibits microbial activity in the bioremediation of saline wastewater. To alleviate osmotic stress, glycine betaine (GB), an osmoprotectant, is added to enhance secretion extracellular polymeric substances (EPS). These EPS are pivotal withstanding environmental stressors, yet intricate interplay between GB supplementation and responses through modifications—encompassing composition, molecular architecture, electrochemical features—remains elusive hypersaline conditions. Here we show strategies for endurance by investigating impact on dynamic alterations properties. Our findings reveal that at 3.5% elevates total (T-EPS) content from 12.50 ± 0.05 24.58 0.96 mg/g dry cell weight. The observed shift zeta potential −28.95 −6.25 mV 0% salinity, respectively, with treatment, indicates a reduction electrostatic repulsion compaction. Notably, protein secondary structure transition β-sheet α-helix, addition, signifies more compact configuration, less susceptible fluctuations. Electrochemical analyses, including cyclic voltammetry (CV) differential pulse (DPV), GB's role promoting release exogenous electron shuttles, such as flavins c-type cytochromes (c-Cyts). enhancement DPV peak areas (QDPV) addition implies increase available transfer sites. This investigation advances our comprehension adaptation mechanisms modifications facilitated habitats.
