Managed aquifer recharge (MAR) is known to increase available water quantity and to improve water quality. However, its implementation is hindered by the concern of polluting aquifers, which might lead to onerous treatment and regulatory requirements for the source water. These requirements might make MAR unsustainable both economically and energetically. To address these concerns, we tested reactive barriers laid at the bottom of infiltration basins to enhance water quality improvement during soil passage. The goal of the barriers was to (1) provide a range of sorption sites to favor the retention of chemical contaminants and pathogens; (2) favor the development of a sequence of redox states to promote the degradation of the most recalcitrant chemical contaminants; and (3) promote the growth of plants both to reduce clogging, and to supply organic carbon and sorption sites. We summarized our experience to show that the barriers did enhance the removal of organic pollutants of concern (e.g., pharmaceuticals and personal care products). However, the barriers did not increase the removal of pathogens beyond traditional MAR systems. We reviewed the literature to suggest improvements on the design of the system to improve pathogen attenuation and to address antibiotic resistance gene transfer.

“…The problem of drug resistance has escalated over the years because of the high isolation rate of clinical multidrug‐resistant (MDR) strains. The mechanism of drug resistance is complex and variable, leading to great challenges during treatment . Carbapenems have been the main treatment for MDR Gram‐negative bacterial for over a decade.…”

Development of an Intelligent Photosensitive Antibacterial Wound Dressing: Simultaneous Detection and Treatment of Bacterial Infection for Accelerated Wound Healing

Antibacterial photodynamic therapy (APDT) is an encouraging therapy modality for bacterial infection. In this work, trithiophene aldehyde (3T‐CHO) as a new photosensitizers was isolated from Herba Ecliptae, and tryptophan (Trp) modified 3T‐CHO improve water solubility and reduced phototoxicity. The photosensitizer‐loaded vesicles were incorporated into a gel scaffold to obtain a wound dressing with detection and antibacterial function. Detection of the presence of pathogenic bacteria, such as Pseudomonas aeruginosa, based on the fluorescence signals was highly efficient and sensitive. The cytotoxin produced by the pathogenic bacteria to induce vesicle lysis, thereby the photosensitive antibacterial agent was released from the vesicle to realize the simultaneous intelligent detection and treatment of pathogenic bacteria. Compared with traditional dressings coated with antibiotics, the synthesized dressing avoids the drawback of pathogenic bacteria developing drug resistance. The proposed microbiologically responsive wound dressing could be used as a general methodology for the design and fabrication of bacterium‐responsive functional biomaterials.

“…Meanwhile, the abundance of Bryobacter is positively correlated to TP [46]. Arenimonas [48], Iamia [49] and Roseiflexus [50] were frequently detected in activated sludge belonging to heterotrophic bacterium; Thiobacillus was both heterotrophy nitrate-reducing bacteria and also autotrophic sulfide-oxidizing [51]. Zhang et al [52] found the predominance of Thiobacillus in different sulfur-based denitrification systems after treating nitrate-contaminated wastewater, and its existence was related to the sulfur cycle.…”

To study the removal performance of a constructed rapid infiltration (CRI) system and its microbial community characteristics, we took the demonstration project of a CRI system that has successfully operated for 15 years as an example, aiming to analyze the CRI system's removal performances for COD, NH 4 +-N, TN and TP. Meanwhile, high-throughput sequencing technology was used for the first time to study the microbial community diversity and structure in the CRI system. The results showed that the average removal efficiencies for COD and NH 4 +-N were 75.52% and 92.94%, and the average removal efficiencies for TN and TP were respectively 39.74% and 42.78%. High-throughput sequencing technology indicated that a variety of bacterial phyla were found in CRI's bacterial communities, including Bacteroidetes, Actinobacteria and Acidobacteria, among which Proteobacteria dominated. At the genus level, a spatial variation was illustrated for the diversity and structure of bacterial communities. The dominant genera on the surface layer (0 cm) of CRI were mainly Nocardioides, Sphingomonas, Bryobacter and other microorganisms that can degrade organic matter, and the dominant genera in the inside (30-120 cm) were mainly microorganisms that play an important role in removing nitrogen. This study provided a theoretical basis for the long-term operation of a CRI system.
