Anaerobic digestion for biogas production is reliant on the tightly coupled synergistic activities of complex microbial consortia. Members uncultured A6 phylotype, within phylum Chloroflexi, are among most abundant genus-level-taxa mesophilic anaerobic digester systems treating primary and surplus sludge from wastewater treatment plants, yet known only by their 16S rRNA gene sequence. This study applied metagenomics to obtain a complete circular genome (2.57 Mbp) representative taxon....
Abstract Enhanced biological phosphorus removal (EBPR) is a globally important biotechnological process and relies on the massive accumulation of phosphate within special microorganisms. Candidatus Accumulibacter conform to classical physiology model for polyphosphate accumulating organisms are widely believed be most player in full-scale EBPR systems. However, it was impossible till now quantify contribution specific microbial clades EBPR. In this study, we have developed new tool directly...
Members of the candidate phylum Acetothermia are globally distributed and detected in various habitats. However, little is known about their physiology ecological importance. In this study, an operational taxonomic unit belonging to was at high abundance four full-scale anaerobic digesters by 16S rRNA gene amplicon sequencing. The first closed genome from obtained differential coverage binning metagenomes scaffolding with long nanopore reads. Genome annotation metabolic reconstruction...
Enhanced biological phosphorus removal (EBPR) involves the cycling of biomass through carbon-rich (feast) and carbon-deficient (famine) conditions, promoting activity polyphosphate accumulating organisms (PAOs). However, several alternate metabolic strategies, without storage, are possessed by other organisms, which can compete with PAO for carbon at potential expense EBPR efficiency. The most studied glycogen (GAOs), utilize aerobically stored to energize anaerobic substrate uptake storage....
Biological degradation of azo-class industrial dye pollutants is the preferred method remediation due to its cost effectiveness and environmentally friendly nature. These however, are known xenobiotics that resist conventional biodegradation methods. The bacterial entails a two-step anaerobic-aerobic sequential process for complete degradation. This study explored possibility utilization microaerophilic mixed consortium from tropical lake sediment conduct single-step mineralization two dyes...
Per- and polyfluoroalkyl substances (PFAS) are persistent organic pollutants of growing environmental human health concern, widely detected across various compartments. Effective remediation strategies essential to mitigate their widespread impacts. This study compared the performance two types commercially available sorbent materials, granular activated carbon (GAC, Filtrasorb-400) organoclays (OC-200, modified Fluoro-sorb-100 Fluoro-sorb-200) for removal three representative PFAS...
Abstract Poly and per fluorinated substances (PFAS) are emerging contaminants of concern that thought to be involved in causing numerous adverse health effects, such as immunosuppression, increased chance cancer development, altered levels hepatic enzyme humans. However, PFAS considered highly persistent resistant biodegradation given the fact C-F bond can have a dissociation energy up 544 kJ/mol. Though many studies reported biodefluorination by bacterial isolates microbial communities,...
The scalability of any microbial fuel cell (MFC)-based system is vital importance if it to be utilized for potential field applications. In this study, an integrated MFC–aerobic bioreactor was investigated its with the purpose treating a simulated dye wastewater and industrial wastewaters originated from textile dyebaths leather tanning. influent containing real fed into reactor in continuous mode at ambient temperature. Three MFC units were act unison as single module treatment continuously...
The use of novel and inexpensive catalysts as replacements for platinum is desirable. In this study, we demonstrate the first time that cost-effective metal oxide nanomaterials conductive polymer polyaniline (PANI) can be directly chemically synthesized on carbon microfiber electrodes to improve performance lake sediment inoculated MFCs. Nanomaterial MnO2, MnO2/polyaniline (PANI), ZnO/NiO ZnO/NiO/PANI attachments were material used cathode electrodes. maximum power densities recorded...

Although phytoremediation is the main method for P-removal and maintaining ecosystem balance in geological phosphorus-enriched soils (PES), little known about structure function of microbial communities PES. Interactions between plants soil microorganisms mainly occur rhizosphere. The aim this work was to investigate composition diversity bacterial found rhizosphere associated with following three dominant plant species: Erianthus rufipilus, Coriaria nepalensis, Pinus yunnanensis.

Abstract Methanogenesis conducted by archaea acts as a competing metabolic pathway that diverts available carbon and electrons away from exo-electrogenic metabolism in mixed culture inoculated microbial fuel cells (MFCs). Statin-class compounds are known to selectively inhibit eukaryotic archaeal versions of HMG Co-A reductase (class-I) enzyme the bacterial version same (class-II) is be unresponsive statins. The results this study demonstrated two model statin Simvastatin Atorvastatin were...
Abstract Marine photosynthetic Microbial fuel cells (mpMFCs) can utilize marine microorganisms to drive electrical energy generating electrochemical reactions.
