Abstract In the present study, organic waste materials, like coconut shell, orange peels, and banana peels were used to produce activated carbon. Chemical activation was carried out using phosphoric acid (H 3 PO 4 ). The temperatures selected at range of 200–300 °C. Surface morphology different carbon derived from materials investigated scanning electron microscope. Pollution removal efficiency carbons by Jar test. jar test 120 rpm, 20 °C temperature for 1 h. Three sizes; 75 μm, 150 μm 425...
Abstract Bacterial communities in wastewater treatment plants (WWTPs) affect plant functionality through their role the removal of pollutants from wastewater. vary extensively based on operating conditions and influent characteristics. The capacity WWTPs can also bacterial community via variations organic or nutrient composition influent. Despite importance considering capacity, characteristics that control assembly are largely unknown. In this study, we discovered Korea Vietnam, which...
Acid Blue 113 (AB113) is a typical azo dye, and the resulting wastewater toxic difficult to remove.The experimental culture was set up for biodegradation of dye AB113, cell growth decolorization were monitored. Transcriptome sequencing performed in presence absence AB113 treatment. The key pathways enzymes involved degradation found through pathway analysis enrichment software (GO, EggNog KEGG).S. melonis B-2 achieved more than 80% within 24 h (50 100 mg/L dye). There positive relationship...
Despite progress in monitoring and modeling Asian dust (AD) events, real-time public hazard prediction based on biological evidence during AD events remains a challenge. Herein, both classification regression tree (CART) multiple linear (MLR) were applied to assess the applicability of for potential urban airborne bacterial hazards using metagenomic analysis qPCR. In present work, Bacillus cereus was screened as pathogenic candidate positively correlated with PM10 concentration (p < 0.05)....
Although extensive efforts have been made to investigate the dynamics of occurrence and abundance antibiotic resistance genes (ARGs) in wastewater treatment plants (WWTPs), understanding acquisition based on WWTP scale potential effects WWTPs is relatively less interest. In this study, metagenomic analysis was carried out whether could be affected by prevalence persistence ARGs mobile genetic elements (MGEs). As a result, 152 ARG subtypes were identified small-scale samples, while 234...
The phase transformation from anatase to rutile in nanocrystalline TiO2 nanorods comprised of length and diameter approximately 35 4 nm, respectively, has been investigated. were synthesized at 100 °C with titanium isopropoxide as a presusor, oleic acid (OLEA) surfactent, trimethylamine catalyst. Characteristic absorption peaks OLEA observed the OLEA-caped after synthesis disappeared annealing process. No (from rutile) 750 for 2 h.

Wastewater treatment plants (WWTPs) have been considered hotspots for the development and dissemination of antibiotic resistance in environment. Although researchers reported a significant increase bioaerosols WWTPs, associated bacterial taxa, genes (ARGs), mobile genetic elements (MGEs) remain relatively unknown. In this study, we investigated abundance occurrences ARGs MGEs, as well community compositions activated sludge (AS), dewatered (DS) (BA) WWTP. total, 153 ARG subtypes belonging to...
This study investigated the potential role of concentration, shape, size, and polymer type microplastics (MP), in addition to microbial community six coastal areas Busan city, South Korea. The results showed that average MP concentration was 94 ± 41 particles·m -3 , particles sized 20 μm –300 accounted for 67.5 9.6% total abundance throughout sites. Further, polyethylene (PE), polypropylene (PP), polystyrene (PS) polymers were abundant among collected fragment- fiber-shaped MPs, implying...
The magnetoresistances (MR's) and magnetic properties of layered manganese oxides, ${\mathrm{Sr}}_{1.6}{R}_{1.4}{\mathrm{Mn}}_{2}{\mathrm{O}}_{7}$ ($R=\mathrm{L}\mathrm{a},\phantom{\rule{0ex}{0ex}}\mathrm{P}\mathrm{r},\phantom{\rule{0ex}{0ex}}\mathrm{N}\mathrm{d},\phantom{\rule{0ex}{0ex}}\mathrm{G}\mathrm{d}$; $R$-327), have been investigated. La-, Pr-, Nd-substituted compounds show metal insulator transitions below 150 K, whereas isostructural Gd-327 compound is semiconducting paramagnetic....
In this study, we performed microbial community analysis to examine diversity and structure in fuel cells (MFCs) seeded with activated sludge from a municipal wastewater treatment plant South Korea. Because anode-attached biofilm populations are particularly important electricity transfer, the ecological characteristics of microbes were explored compared those grown suspension an anode chamber. 16S rDNA-based showed that degree biofilms was greater than originally as well suspension-grown...
Hepatic ischemia/reperfusion (I/R) injury is one of the leading causes mortality following partial hepatectomy, liver transplantation, hypovolemic shock and trauma; however, effective therapeutic targets for treatment hepatic I/R are lacking. Recent studies have shown that diminazene aceturate (DIZE) has protective effects against inflammation, oxidative stress cell death, which main pathogenetic mechanisms associated with injury. However, mechanistic DIZE exerts on remain unknown. C57BL/6...
