Bacteriophage inactivation at the air-water-solid interface in dynamic batch systems.
Bacteriophages have been widely used as surrogates for human enteric viruses in many studies on virus transport and fate. In this investigation, the fates of three bacteriophages, MS2, R17, and phiX174, were studied in a series of dynamic batch experiments. Both MS2 and R17 readily underwent inactivation in batch experiments where solutions of each phage were percolated through tubes packed wit...
متن کاملRole of the air-water-solid interface in bacteriophage sorption experiments.
Batch sorption experiments were carried out with the bacteriophages MS2 and phi X174. Two types of reactor vessels, polypropylene and glass, were used. Consistently lower concentrations of MS2 were found in the liquid phase in the absence of soil (control blanks) than in the presence of soil after mixing. High levels of MS2 inactivation (approximately 99.9%) were observed in control tubes made ...
متن کاملOrganic ions at the air/water interface
Direct spectroscopic evidence of the presence of organic phenolate ions at the air/aqueous interface has been established using the nonlinear spectroscopic technique of vibrational sum frequency generation (SFG). By probing the phenol C–OH and the phenolate C–O vibrational stretches, which occur in the range of 1200–1300 cm and are distinguishable, we have succeeded in determining the identitie...
متن کاملHydrated electrons at the water/air interface.
The dynamics of hydrated electrons at the water/air interface are investigated using time-resolved second-harmonic generation spectroscopy. Initial solvation occurs in approximately 1 ps, and the electron remains at the interface for >750 ps. The location of the electron relative to the dividing surface is investigated using surfactants, which show that the electron is hydrated in the interfaci...
متن کاملBacterial Accumulation at the Air-Water Interface
Accumulation at the air-water interface of four bacterial strains with different hydrophobicities was studied. To exclude system influences, both a static batch system and a dynamic system involving rising bubbles were used. All bacteria accumulated at the air-water interface in both systems. Generally, attachment to the air-water interface increased with bacterial surface hydrophobicity. Accum...
