In arid and semi-arid regions, the use of treated wastewater (TWW) for irrigation is gaining ground to alleviate pressure on natural water sources. Despite said treatment, existing methods fail eliminate potentially dangerous contaminants. As such, this study assessed impact long-term TWW (5 25 years) soil physicochemical properties bacterial resistance heavy metals (Pb, Cu, Cd) antibiotics (tetracycline amoxicillin).

Deciphering unclear microbial interactions is key to improving biological wastewater treatment processes. Microbial predation and parasitism in ecosystems are unexplored survival strategies that have long been known recently attracted attention because these interspecies may contribute the reduction of excess sludge. Here, community profiling 600 activated sludge samples taken from six industrial one municipal processes (WWTPs) was conducted. To identify shared lineages WWTPs, constituents were defined as family level taxa had ≥ 0.1% average relative abundance detected all The analysis assigned 106 families WWTPs. Correlation showed 98 significantly correlated with total carbon (TC) and/or nitrogen (TN) concentrations, suggesting they remediation. Most possible predatory or parasitic bacteria belonging phyla Bdellovibrionota, Myxococcota, Candidatus Patescibacteria found be negatively TC/TN; thus, frequently present WWTPs could involved removal carbon/nitrogen derived cell components. Shotgun metagenome-resolved metabolic reconstructions indicated gene homologs associated conserved Ca. genomes (e.g., host interaction (hit) locus, Tad-like secretion complexes, type IV pilus assembly proteins).

Phosphogypsum (PG) is the largest by-product of phosphate industry. Nearly 300 M tons PG are annually discarded, which 58% dry stacked. The exposure stacks to rainwater and processed waters moisture creates hydraulic pressure, generating acidic leachates into nearby aquifer systems. Because its elevated levels sulfates, phosphorus (P) heavy metals, water leachate can negatively affect surrounding environments. This work investigates effect activity on leaching, by studying different PG:Water ratios leaching process, followed anaerobic bioremediation through biological sulfate removal (BSRA). later involves using sulfate-reducing bacteria consortium within an bioreactor, allowing a simultaneous monitoring leachate's biochemical changes, impurities removal, microbial community dynamics results determined highest sulfates from with ratio 1:200 (w:v).

Habitat and temporal variation can both influence microbial community dynamics, although their relative importance in reservoir buffer zones with complex hydrology regimes dramatically altered environments remains controversial. To elucidate this, we investigated spatiotemporal soil bacterial diversity ecological processes from the flooding period to dry (April June, respectively) using high-throughput 16S amplicon sequencing three habitats (abandoned cropland, grassland, woodland) within Chushandian Reservoir's strip, China. The results showed that habitat was more important than shaping zone. Bacterial communities responded terms of species composition function; affected mostly by altering abundance shared causing resurgence or extinction specific taxa same habitat. main driver these changes resilience capacity changing moisture environment. magnitude underlying mechanisms differed markedly between habitats, owing characteristics vegetation, thus allocation ratios different vegetation types landscape should pay attention for zone management, improving integrated benefits ecosystem a multiscale.
