Application of response surface methodology for modeling and optimization of Bacillus subtilis spores inactivation by the UV/persulfate process
Stronger disinfection techniques are required to inactivate Bacillus subtilis spores as surrogate microorganisms for Cryptosporidium parvum oocysts. In this study, the effects of UV and persulfate separately and also in combination were investigated on B. subtilis spore inactivation. Central composite design and response surface methodology were used to optimize target microorganism ...

Cryptosporidium spp. andGiardia spp. in surface water supply of Campinas, Southeast BrazilSurface water contaminated by domestic sewage discharges is a potential source of pathogens, including protozoa. During 2005–2006, the source water (Atibaia River) of the Surface Water Treatment Plant (WTP) of Campinas city, São Paulo, Brazil was sampled to obtain an assessment of Cryptosporidium oocyst and Giardia cyst concentrations. Calcium carbonate flocculation (CCF) and membrane filtration ...

Immunomagnetic separation study applied to detection of Giardia spp. cysts and Cryptosporidium spp. oocysts in water samples
In this work we studied the IMS purification comparing acid (n = 12) and heat (n = 12) dissociation procedures and investigated the possible losses of target organism in this step. Reagent water samples were directly inoculated with Giardia spp. cysts and Cryptosporidium spp. oocysts (BTF Easy Seed™). Acid dissociation showed higher mean recovery efficiency and precision than heat ...
