Environmentally-related contaminants of high concern: Potential sources and analytical modalities for detection, quantification, and treatment

Environment International, Год журнала: 2018, Номер 122, С. 52 - 66

Опубликована: Ноя. 28, 2018

In recent years, emerging contaminants (ECs) of high concern are broadly distributed throughout the environmental matrices because various industrial practices and anthropogenic inputs, i.e., human-made activities. With ever increasing scientific knowledge, technological advancement, socio-economic awareness, people now more about widespread distribution environmentally related ECs concern. As, possess serious ecological threats potential risks to human health aquatic life, even at minor concentrations. The controlled or uncontrolled discharge long-term persistence that includes micro-pollutants, endocrine disruptors (EDs), pesticides, pharmaceuticals, hormones, toxins, industrially-related synthetic dyes dyes-containing hazardous pollutants, etc. pose a significant challenge policy regulators, engineers, community. conventional treatment technologies proved ineffective for complete elimination removal an array in biological samples. order overcome aforementioned threats, tremendous research efforts have been made boost efficiency remediation techniques develop new modalities detect, quantify treat samples efficiently. boom biotechnology engineering offers opportunities advanced innovative field water treatment. This review discusses hazards associated with bodies, surface water, groundwater, wastewater streams. Life-cycle (micro)-pollutants suitable examples from sources viewpoints is also discussed. later part focuses on cost-effective (removal) approaches phase-changing these

Опубликована: Июль 1, 2020

The levels of pesticides in water have increased due to their excessive use the modern agricultural domain. Choosing a suitable treatment method for pesticide removal depends on type and efficacy process. This review critically discusses provides detailed description variety chemical, physical, biological approaches from water, such as advanced oxidation processes, adsorption, activated sludge, membrane bioreactors, technologies. Both single-treatment hybrid methods are thoroughly described discussed. techniques offers potential opportunities develop innovative techniques. A thorough analysis influent composition recognition best technique is very important design plant that targets maximum possible rate different types pesticides. Furthermore, decentralization was also discussed which it an approach would lead better effluent quality lower prices. Many affordable sludge adsorption by adsorbents showed high treating

Advances in the Microbiology of Stenotrophomonas maltophilia

Clinical Microbiology Reviews, Год журнала: 2021, Номер 34(3)

Опубликована: Май 29, 2021

Stenotrophomonas maltophilia is an opportunistic pathogen of significant concern to susceptible patient populations. This can cause nosocomial and community-acquired respiratory bloodstream infections various other in humans. Sources include water, plant rhizospheres, animals, foods. Studies the genetic heterogeneity S. strains have identified several new genogroups suggested adaptation this its habitats. The mechanisms used by during pathogenesis continue be uncovered explored. virulence factors use motility, biofilm formation, iron acquisition mechanisms, outer membrane components, protein secretion systems, extracellular enzymes, antimicrobial resistance mechanisms. intrinsically drug resistant array different antibiotics uses a broad arsenal protect itself against antimicrobials. Surveillance studies recorded increases for maltophilia, prompting strategies developed opportunist. interactions environmental bacterium with microorganisms are being elucidated. products applications biotechnology, including agriculture, biocontrol, bioremediation.

Emerging contaminants affect the microbiome of water systems—strategies for their mitigation

Опубликована: Сен. 18, 2020

Abstract The presence of emerging contaminants (ECs) in the environment has been consistently recognized as a worldwide concern. ECs may be defined chemicals or materials found at trace concentrations with potential, perceived, real risk to “One Health” trilogy (environment, human, and animal health). main concern regarding pharmaceuticals particular antibiotics is widespread dissemination antimicrobial resistance. Nevertheless, non-antimicrobials also interact microorganisms both bulk phase biofilms. In fact, drugs not developed for chemotherapy can exert an action and, therefore, selective pressure on microorganisms. This review aims provide answers questions typically ignored epidemiological environmental monitoring studies focus water systems, particularly drinking (DW): Do exposure changes behavior microorganisms? May non-antibiotic affect tolerance antimicrobials? interfere biofilm function? Are ECs-induced microbial public health concern? Nowadays, these are still very limited. However, this study demonstrates that some have significant effects behavior. most studied pharmaceuticals, antibiotics, carbamazepine diclofenac. caused by antibiotic other agents acquisition spread resistance seems unquestionable. development biofilms, conclusions different controversial. dissimilar findings propose standardized tests needed accurate assessment microbiome systems. variability experimental conditions, combined mixtures well lack information about non-pharmaceutical constitute challenge overcome order improve prioritization.

The gut microbiome is emerging as a key regulator of brain function and behavior associated with symptoms several neurological disorders. There evidence that alterations in the microbiota are seen epilepsy response to seizure interventions. In this review, we highlight recent studies reporting individuals refractory exhibit altered composition microbiota. We further discuss antibiotic treatment infection microbiome-related factors influence susceptibility humans animal models. addition, evaluate how may mediate effects ketogenic diet, probiotic treatment, anti-epileptic drugs on reducing both frequency severity. Finally, assess open questions interrogating roles for address prospect continued research uncover fundamental insights understanding risk epilepsy, well novel approaches treating epilepsy.

Antimicrobial Activity of Non-steroidal Anti-inflammatory Drugs on Biofilm: Current Evidence and Potential for Drug Repurposing

Frontiers in Microbiology, Год журнала: 2021, Номер 12

Опубликована: Июль 27, 2021

It has been demonstrated that some non-steroidal anti-inflammatory drugs (NSAIDs), like acetylsalicylic acid, diclofenac, and ibuprofen, have anti-biofilm activity in concentrations found human pharmacokinetic studies, which could fuel an interest repurposing these well tolerated as adjunctive therapies for biofilm-related infections. Here we sought to review the currently available data on of NSAIDs its relevance a clinical context. We performed systematic literature identify most commonly tested last 5 years, bacterial species be responsive their actions, emergence resistance molecules. studies investigating NSAIDs’ against biofilms were vitro , frequently non-clinical isolates, may not adequately represent populations cause clinically-relevant Furthermore, concerning antibiotic are scarce, with divergent outcomes. Although potential use control infections seems exciting avenue, there is paucity using appropriate vivo models biofilm or controlled trials support agents.

An Overview of the Impact of Pharmaceuticals on Aquatic Microbial Communities

Antibiotics, Год журнала: 2022, Номер 11(12), С. 1700 - 1700

Опубликована: Ноя. 25, 2022

Pharmaceuticals are present as pollutants in several ecosystems worldwide. Despite the reduced concentrations at which they detected, their negative impact on natural biota constitutes a global concern. The consequences of pharmaceuticals’ presence water sources and food have been evaluated with higher detail for human health. However, although most pharmaceuticals detected environment had not designed to act against microorganisms, it is utmost importance understand environmental native microbiota. Microbial communities can suffer serious from environment, may directly public health ecosystem equilibrium. Among this class pollutants, ones that studied more antibiotics. This work aims provide an overview impacts different biofilms, specifically biofilms aquatic engineered systems. alterations caused biofilm function characteristics, well bacteria antimicrobial tolerance consequently associated risks health, also reviewed. information already available topic, need additional data urges assessment emerging microbial potential impacts.
