“…The key objective for farmers is to raise their production by using wastewater as a rich nutrient and increasing their net return on agriculture. Present new and creative regulations influence wastewater management costs (Priya et al 2021 ; Stentoft et al 2021 ). Small-scale industries and corporations can apply effluent standards and fees to improve wastewater management.…”

Environmental rethinking of wastewater drains to manage environmental pollution and alleviate water scarcity

The conservation of water resources in developed countries has become an increasing concern. In integrated water resource management, water quality indicators are critical. The low groundwater quality quantitates mainly attributed to the absence of protection systems for polluted streams that collect and recycle the untreated wastewater. Egypt has a limited river network; thus, the supply of water resources remains inadequate to satisfy domestic demand. In this regard, high-quality groundwater is one of the main strategies for saving water supplies with water shortage problems. This paper investigates the critical issues of groundwater protection and environmental management of polluted streams, leading to overcoming water demand-about 18 × 10 3 km of polluted open streams with a discharge of 9.70 billion Cubic Metter (BCM). We have proposed proposals and policies for the safe use of groundwater and reuse of wastewater recycling for agriculture and other purposes. This study was carried out using the numerical model MODFLOW and MT3DMS—(Mass Transport 3-Dimension Multi-Species) to assess the Wastewater Treated Plant's (WWTP) best location and the critical path for using different lining materials of polluted streams to avoid groundwater contamination. The three contaminants are BOD, COD, and TDS. Five scenarios were applied for mitigating the impact of polluted water: (1) abstraction forcing, (2) installing the WWTP at the outlet of the main basin drain with and without a lining of main and sub-basin streams (base case), (3) lining of main and sub-main streams, (4) installing WWTP at the outlet of the sub-basin streams, and (5) lining of the sub-basin and installing WWTP at the outlet of the sub-basin. The results showed that the best location of WWTP in polluted streams is developed at the outlets of sub-basin with the treatment of main basin water and the lining of sub-basins streams. The contamination was reduced by 76.07, 76.38, and 75.67% for BOD, COD, and TDS, respectively, using Cascade Aeration Biofilter or Trickling Filter, Enhancing Solar water Disinfection [(CABFESD)/(CATFESD)] and High-Density Polyethylene lining. This method is highly effective and safe for groundwater and surface water environmental protection. This study could be managing the water poverty for polluted streams and groundwater in the Global South and satisfy the environmental issues to improve water quality and reduce the treatment and health cost in these regions.

“…However, desirable outcomes were not consistently achieved, and most of the variation in clinical outcome might relate to our yet inability to properly understand and predict the fundamental basis and outcomes of community coalescence. Likewise, coalescence has also been used to engineer soil microbial assemblages capable of steering restoration in ex-arable lands ( Wubs et al, 2016 ), boosting crop production in organic agriculture ( Ramos et al, 2019 ), or enhancing biomethane production in anaerobic digesters ( Sierocinski et al, 2017 ), and has even been used to reduce nutrient flow-through and enhance recovery at wastewater treatment facilities ( Wagner et al, 2002 ; Priya et al, 2021 ). Recently, the concept of meta-gut was proposed as a conceptual framework that utilizes coalescence to integrate the gut microbiome of excretion with the function these fecal microbiomes provide outside the host.…”

Ecological and Evolutionary Implications of Microbial Dispersal

Dispersal is simply defined as the movement of species across space and time. Despite this terse definition, dispersal is an essential process with direct ecological and evolutionary implications that modulate community assembly and turnover. Seminal ecological studies have shown that environmental context (e.g., local edaphic properties, resident community), dispersal timing and frequency, and species traits, collectively account for patterns of species distribution resulting in either their persistence or unsuccessful establishment within local communities. Despite the key importance of this process, relatively little is known about how dispersal operates in microbiomes across divergent systems and community types. Here, we discuss parallels of macro- and micro-organismal ecology with a focus on idiosyncrasies that may lead to novel mechanisms by which dispersal affects the structure and function of microbiomes. Within the context of ecological implications, we revise the importance of short- and long-distance microbial dispersal through active and passive mechanisms, species traits, and community coalescence, and how these align with recent advances in metacommunity theory. Conversely, we enumerate how microbial dispersal can affect diversification rates of species by promoting gene influxes within local communities and/or shifting genes and allele frequencies via migration or de novo changes (e.g., horizontal gene transfer). Finally, we synthesize how observed microbial assemblages are the dynamic outcome of both successful and unsuccessful dispersal events of taxa and discuss these concepts in line with the literature, thus enabling a richer appreciation of this process in microbiome research.

“…Pharmaceutical and personal care products are not completely removed by conventional wastewater treatment processes; therefore, biotechnology treatment needs to be applied to reach minimum concentration when disposal to water surface (Mohammed et al, 2021). Constructed wetlands (CWs) are the biotechnology to remove micropollutants via filtration, sedimentation, adsorption, and plant-bacteria interaction (Priya et al, 2021).…”

Pharmaceutical compounds have been introduced into the aquatic ecosystems in multiple ways and sources, which negatively affects the health of the environment and humans. The river near the hospital sewage disposal is host environment for drug-resistant bacteria (DRB). In this context, the aim of the research was to detect the presence of pharmaceuticals in hospital wastewater, after treatment, at river point followed by isolation of bacteria and test for resistant pharmaceutical compound. Fifteen species of bacteria isolated by angiogenic methods were identified and tested using the well diffusion test to determine the resistance of selected bacteria to ibuprofen by survival assessment. This study showed that the ibuprofen detected by GC-mass was available in all selected points at a concentration of 3 to 120 mg/L. Lecuco. mesen.cremris and Koc.rosea have a high ability to break down the ibuprofen compound. Thus, the bacteria isolated from hospital wastewater can biologically degrade ibuprofen.
