As water reuse applications expand, there is a need for more comprehensive means to assess quality. Microbiome analysis could provide the ability supplement fecal indicators and pathogen profiling toward defining "healthy" drinking microbiota while also providing insight into impact of treatment distribution. Here, we utilized 16S rRNA gene amplicon sequencing identify signature features in composition across wide spectrum types (potable conventional, potable reuse, nonpotable reuse). A clear distinction was found as function intended use (e.g., vs nonpotable) very broad range U.S. systems at both point compliance (Betadisper

Currently, there is a growing concern about water scarcity. The rising demand for wastewater treatment systems that facilitate the reuse of has resulted in focus on use microalgae sustainable treatments. These methods not only eliminate nutrients from but also produce biomass can be used to obtain high-value products. This study aimed observe effect different hydraulic retention times (HRTs) and treated urban (TUWW) percentages growth nutrient consumption membrane photobioreactors. Microalgae increases with HRT regardless percentage TUWW. Biomass concentration stabilises at between 40% 60% TUWW significantly when 100% used, resulting highest concentrations. As increases, ammonium total nitrogen rise. A positive trend was observed increasing TUWW, reaching its peak optimal conditions removal are achieved 7-day as influent, which confirmed response surface methodology.

The emergence plastic an alarming pollutant poses significant threat the sustainability agricultural ecosystems, worldwide food security This study aimed explore efficacy biochar-based synthetic community (SynCom) in mitigating RC-MPs-induced stress on plant growth, soil physicochemical properties microbial communities peanuts cultivated RC-MPs contaminated soil. findings revealed that significantly reduced peanut shoot dry weight, root vigor, nodule quantity, enzyme activity, urease dehydrogenase well available potassium, bacterial abundance (p < 0.05). Moreover, identified highly effective growth-promoting rhizobacteria (PGPR) from rhizosphere, which were subsequently integrated into SynCom immobilized within biochar. Application increased biomass, number, antioxidant alongside enhancing activity rhizosphere Interestingly, under high-dose treatment, there was increase diversity, exhibiting distinct clustering patterns. However, application did not induce alterations this regard. In summary, investigated proved be potential amendment for deleterious effects preserving functionality. presents promising solution challenges posed by soil, offering novel avenues remediation.
