Health-relevant microorganisms present in natural surface waters and engineered treatment
systems that are exposed to sunlight can be inactivated by a complex set of interacting …

Enterococci are common, commensal members of gut communities in mammals and birds,
yet they are also opportunistic pathogens that cause millions of human and animal infections …

Fecal pollution of recreational waters can cause scenic blight and pose a threat to public
health, resulting in beach advisories and closures. Fecal indicator bacteria (total and fecal …

Sunlight inactivation in fresh (river) water of fecal coliforms, enterococci, Escherichia coli,
somatic coliphages, and F-RNA phages from waste stabilization pond (WSP) effluent was …

Fecal microorganisms can enter water bodies in diverse ways, including runoff, sewage
discharge, and direct fecal deposition. Once in water, the microorganisms experience …

Enteric bacteria exposed to the marine environment simultaneously encounter a variety of
abiotic and biotic challenges. Among the former, light appears to be critical in affecting …

Potential fecal contamination of sand in the wave-washed zone of public bathing beaches is
overlooked in beach monitoring programs. Activity in this zone can bring pathogens to the …

In recent years, there has been a tremendous amount of research and development in the
area of photocatalysis, a process included in a special class of oxidation techniques defined …

Bactericidal action of illuminated TiO2 on pure culture of Escherichia coli K12 and bacterial
consortium was studied. Photocatalytic E. coli inactivation rate was dependent on the …

Sunlight exposure is considered to be the most important cause of “natural” disinfection in
waste stabilisation ponds (WSPs). We examined the influence of dissolved oxygen (DO), pH …
