Sustainable Development Goals (SDGs) as a Framework for Corporate Social Responsibility (CSR)

Sustainability, Год журнала: 2022, Номер 14(3), С. 1222 - 1222

Опубликована: Янв. 21, 2022

Corporate Social Responsibility (CSR) has been an articulated practice for over 7 decades. Still, most corporations lack integrated framework to develop a strategic, balanced, and effective approach achieving excellence in CSR. Considering the world’s critical situation during COVID-19 pandemic, such is even more crucial now. We suggest subsuming CRS categories under Sustainable Development Goals (SDGs) be used that they subsume CSR since SDGs are comprehensive agenda designed whole planet. This study presents new drivers model novel model. Then, it highlights advantages of integrating framework. The proposed benefits from both SDGs, addresses current future needs, offers better roadmap with measurable outcomes.

Key considerations for pathogen surveillance in wastewater

The Science of The Total Environment, Год журнала: 2024, Номер 945, С. 173862 - 173862

Wastewater surveillance (WWS) has received significant attention as a rapid, sensitive, and cost-effective tool for monitoring various pathogens in community. WWS is employed to assess the spatial temporal trends of diseases identify their early appearances reappearances, well detect novel mutated variants. However, shedding rates vary significantly depending on factors such disease severity, physiology affected individuals, characteristics pathogen. Furthermore, may exhibit differential fate decay kinetics sewerage system. Variable affect detection wastewater. This influence interpretation results conclusions studies. When selecting pathogen WWS, it essential consider it's specific characteristics. If data are not readily available, fate, decay, should be assessed before conducting surveillance. Alternatively, these can compared those similar which available.

Bacteriophages in sewage: abundance, roles, and applications

FEMS Microbes, Год журнала: 2022, Номер 3

Опубликована: Янв. 1, 2022

The raw sewage that flows through systems contains a complex microbial community whose main source is the human gut microbiome, with bacteriophages being as abundant bacteria or even more so. Phages infect common strains of bacteriome and transient bacterial pathogens have been isolated in sewage, other phages corresponding to non-sewage inputs. Although do not seem replicate during their transit sewers, they predominate at entrance wastewater treatment plants, inside which dominant populations undergo swift change. sheer abundance virome prompts several questions, some are addressed this review. There growing concern about potential role horizontal transfer genes, including those related pathogenicity antibiotic resistance. On hand, used indicators fecal/viral water pollution tracking markers introduced quality legislation. Other applications enteric control undesirable impede efficacy treatments, biofilm formation on membranes, still researched.

Isolation and characterization of a lytic bacteriophage against Pseudomonas aeruginosa

Scientific Reports, Год журнала: 2021, Номер 11(1)

Опубликована: Сен. 29, 2021

Abstract In recent years, the use of bacteriophages (or 'phages') against multidrug-resistant (MDR) bacteria including Pseudomonas aeruginosa has drawn considerable attention, globally. this work, we report isolation and detailed characterization a highly lytic Pseudomonasphage DRL-P1 isolated from wastewater. Under TEM, appeared as member phage family Myoviridae . featured rapid adsorption (~ 5 min), short-latency 30 large burst size 100 PFU per infected cell). can withstand wide temperature range (4 °C to 40 °C) pH (5.0 10.0) conditions. The 66,243 bp genome (MN564818) encodes at least 93 ORFs, which 36 were functionally annotated based on homology with similar proteins available in databases. Comparative analyses related genomes suggest an independent evolutionary history discrete taxonomic position within genus Pbunavirus No toxin or antibiotic resistance genes was identified. is tolerant lyophilization encapsulation techniques retained activity even after 18 months storage. We also demonstrated decontaminating potentials vitro, artificially contaminated cover-slip model. To best our knowledge, first be reported India. Our study suggests potential candidate for various applications.

Bacteriophages in Biological Wastewater Treatment Systems: Occurrence, Characterization, and Function

Frontiers in Microbiology, Год журнала: 2021, Номер 12

Опубликована: Сен. 30, 2021

Phage bacteria interactions can affect structure, dynamics, and function of microbial communities. In the context biological wastewater treatment (BWT), presence phages alter efficiency process influence quality treated effluent. The active role in BWT has been demonstrated, but many questions remain unanswered regarding diversity these engineered environments, dynamics infection, determination bacterial hosts, impact their activity full-scale processes. A deeper understanding phage ecology lead improvement monitoring control, promote higher influent quality, potentiate use as biocontrol agents. this review, we highlight suitable methods for studying adapted from other research fields, provide a critical overview on current state knowledge effect structure communities, gaps, opportunities, priority to be addressed future research.

Global diversity and biogeography of DNA viral communities in activated sludge systems

Microbiome, Год журнала: 2023, Номер 11(1)

Опубликована: Окт. 21, 2023

Abstract Background Activated sludge (AS) systems in wastewater treatment plants (WWTPs) harbor enormous viruses that regulate microbial metabolism and nutrient cycling, significantly influencing the stability of AS systems. However, our knowledge about diversity viral taxonomic groups functional traits global is still limited. To address this gap, we investigated biogeography DNA communities using 85,114 operational units (vOTUs) recovered from 144 samples collected across 54 WWTPs 13 different countries. Results their exhibited distance-decay relationship (DDR) at scale latitudinal gradient (LDG) equator to mid-latitude. Furthermore, it was observed community gene structures were largely driven by geographic factors types, which more important. Carrying disseminating auxiliary metabolic genes (AMGs) associated with degradation polysaccharides, sulfate reduction, denitrification, organic phosphoester hydrolysis, as well lysis crucial microbes govern biogeochemical cycles two major ways could functions. It worth noting study revealed a high abundance antibiotic resistance (ARGs) genomes, suggesting key reservoirs ARGs Conclusions Our results demonstrated highly diverse Viral host virus-mediated HGT can cycles, thus affecting performance These findings provide important insights into diversity, function, ecology on scale.

One solution to current water scarcity is the reuse of treated wastewater. Water systems have be examined as a whole, including efficacy water-reclamation treatments and operation steps from wastewater inlet into WWTP irrigation endpoint, irrigated crop. In this study, monitoring human enteric viruses coliphages were assessed in two reused systems. The presence hepatitis A virus (HAV) noroviruses genogroups I II (GI GII) analyzed by real-time RT-PCR (RT-qPCR) (n = 475) leafy green samples 95). Total double-layer agar plaque technique. prevalence HAV was very low (c.a. 2%), mostly linked raw sewage, while for samples, none positive HAV. greens, norovirus (less than 5–6%). highest reductions observed taken reservoirs used growers near growing field. die-off during storage due solar radiation could considered an additional improvement. Reclamation significantly reduced counts GI GII reclaimed water. However, coliphage 5 log) do not comply with specifications included new European regulation on (≥6.0 log). Correlations between found only high concentrations (>4.5 log PFU/100 mL). percentage (20–25%) negative total showed moderate (1–3 logs), indicating that are most suitable indicator possible viruses.
