Interfacial behavior of RNA-free MS2 bacteriophage particles
… was investigated in this study. The RNA of bacteriophage MS2 was removed and the empty capsid characterized and compared to intact MS2. Transmission electron microscopy was used to ensure that the MS2 capsid was intact and RNA removed. Electrophoretic mobility, aggregation kinetics and …

Mechanisms of MS2 bacteriophage removal by ultrafiltration membrane with different foulants
… of 40 nm nominal pore size was used to study bacteriophage MS2 removal under different membrane conditions. The membrane conditions were subject to fouling of soluble microbial products (SMP), which was extracted from membrane bio-reactor (MBR) feed water, and cleaning methods including …

Polysulfone ultrafiltration membranes impregnated with silver nanoparticles show improved biofouling resistance and virus removal
… mendocina KR1, and enhanced the removal of MS2 bacteriophage. Nanosilver incorporation also increased membrane hydrophilicity, reducing the potential for other types of membrane fouling. Thus, the incorporation of nAg into polysulfone ultrafiltration membranes increases both membrane …

Iron oxide amended biosand filters for virus removal
… flow, small-scale glass columns showed high MS2 bacteriophage removal in an iron-amended sand column (5-log10) compared to a sand only column (0.5-log10) over 20 pore volumes. Additionally, two experiments with a column containing iron particles revealed 4 and 5 log10 removal of rotavirus in …

Mechanism of virus removal and nutrient reduction and modification of bio-sand filter
… in the feed water on the removal of bacteriophage MS2 using bio-sand filters (BSFs) and analyze the formation of the bacterial community in BSFs, and modify BSFs with different packing materials and structures. Five bench-scale BSFs were constructed from 4 inches PVC. Two BSFs were …

A global sensitivity analysis of solar virus inactivation modeling
… mechanistic model for three virus species (MS2 bacteriophage, phiX174 bacteriophage, and human adenovirus) and two water types (natural surface water, waste stabilization pond water), and a global sensitivity analysis was performed to quantitatively apportion the uncertainty of solar virus …

Development of novel bio/nano interfaces for materials science and biomedical applications
<p>Virus-like particles (VLPs) of MS2 bacteriophage possess a variety of characteristics that enable their use in biomedical and materials science applications. MS2 VLPs are perfectly monodisperse and possess a highly regular periodic structure. Their protein capsids can be modified in precise …

Generation and biological collection efficiency of MS2 bioaerosol for the evaluation of aerosol filtration devices
… activated carbon fiber cloth (ACFC) filter. MS2 bacteriophage was used as a model virus. Three tasks were conducted. The first task involved the development of a modified Liquid Sparging Aerosolizer (LSA) generator, which was fabricated to produce a stable supply of tested bioaerosol. The …

Roles of singlet oxygen and triplet excited state of dissolved organic matter formed by different organic matters in bacteriophage MS2 inactivation
Inactivation of bacteriophage MS2 by reactive oxygen species (ROS) produced by irradiation with simulated sunlight, containing visible light and ultraviolet light with wavelengths greater than 320 nm, was investigated. The results from experiments with synthetic sensitizers Rose Bengal, …

Control of viruses in drinking water with visible light-activated TiON/PdO photocatalyst: performance dynamics associated with regeneration and activation
… was able to achieve four-logs of viral surrogate MS2 phage removal, with both dark and photocatalytic effects. Sustained regeneration potential of the material was tested using ozonation, which has been shown to completely restore the removal capacity after repeated use without degradation. A …

Oxidative Treatment of Emerging Micropollutants and Viral Pathogens by Potassium Permanganate and Ferrate: Kinetics and Mechanisms
… for inactivation of a surrogate viral pathogen, MS2 bacteriophage. Survey tests show that permanganate and ferrate are both selective oxidants that target compounds with specific electron-rich moieties, including olefin, phenol, amine, cyclopropyl, thioether, and alkyne groups. Detailed kinetics …
