Precipitation effects on parasite, indicator bacteria, and wastewater micropollutant loads from a water resource recovery facility influent and effluent.

Precipitation effects on parasite, indicator bacteria, and wastewater micropollutant loads from a water resource recovery facility influent and effluent. J Water Health. 2019 Oct;17(5):701-716 Authors: Tolouei S, Autixier L, Taghipour M, Burnet JB, Bonsteel J, Duy SV, Sauvé S, Prévost M, Dorner S Abstract The variability of fecal microorganisms and wastewater micropollutants (WWMPs) loads in relation to influent flow rates was evaluated for a water resource recovery facility (WRRF) in support of a vulnerability assessment of a drinking water source. Incomplete treatment and bypass discharges often occur following intense precipitation events that represent conditions that deviate from normal operation. Parasites, fecal indicator bacteria, and WWMPs concentrations and flow rate were measured at the WRRF influent and effluent during dry and wet weather periods. Influent concentrations were measured to characterize potential bypass concentrations that occur during wet weather. Maximum influent Giardia and C. perfringens loads and maximum effluent Escherichia coli and C. perfringens loads were observed during wet weather. Influent median loads of Cryptosporidium and Giardia were 6.8 log oocysts/day and 7.9 log cysts/day per 1,000 people. Effluent median loads were 3.9 log oocysts/day and 6.3 log cysts/day per 1,000 people. High loads of microbial contaminants can occur during WRRF bypasses following wet weather and increase with increasing flow ...

An attempt was made to understand the mechanism of pore formation by analyzing optical micrographs and SEM images in addition to solution viscosity of organic phase and interfacial tension values between organic and aqueous phases. The ...

Conclusion: The recombinant wild-type protein showed its maximal activity at pH 2, more acidic pH than that found in the crude venom. The glycosylation was predicted to be responsible for the pH optimum and thermal stability of the enzymes activity.

In order to assess the strength and reach of such evolutionary links, we need to have a broad understanding of the pinworm diversity associated with primates. Here, we employed an integrative taxonomic approach to assess pinworm divers...

The bidentate chelating ligands formed in the reaction (in situ) via the nucleophilic addition. The molecular structures of complexes [Cu(L1)2](ClO4)2 and [Cu(L3)2](ClO4)2 were determined by single crystal X-ray diffraction studies. In both structures, each Cu(II) adopts distorted square planar geometry bonded to the imine nitrogen atoms of two bidentate ligands. The DNA binding ca...

In this study, we used an E. coli system for the efficient production of recombinant proteins and developed a bicistronic design (BCD) expression construct consisting of two copies of the C-terminal (247–370) domain of the alpha toxin (CPA-C) in the first cistron, followed by Cholera Toxin B (CTB) linked with another two copies of CPA-C in the second cistron that is controlled by a single promoter. Rabbits were immunized twice with purified proteins (rCPA-C rCTB-CPA-C) produced in the BCD expression system, with an inactivated recombinant E. coli vaccine (RE), C. perfringens formaldehyde-inactivated alpha toxoid (FA-...

In this study, TiO2/Zn2TiO4/Ag nanocomposite was prepared using sol-gel method and characterized by FESEM, EDX, XRD, TGA, UV–vis spectrophotometry, and FTIR techniques. Different sunscreen creams were formulated by incorporating the nanocomposite and TiO2 nanoparticles and the Sun Protection Factor (SPF) against ultraviolet radiation and antibacterial activity were examined. The antibacterial activity of synthesized TiO2/Zn2TiO4/Ag nanocomposite was investigated against gram positive (S. aureus) and gram negative (Escherichia coli). TiO2/Zn2TiO4/Ag nanocomposite has a higher protective factor compared to TiO2 nanopar...
