Inactivation of animal viruses during sewage sludge treatment.
Using a previously developed filter adsorption technique, the inactivation of a human rotavirus, a coxsackievirus B5, and a bovine parvovirus was monitored during sludge treatment processes. During conventional anaerobic mesophilic digestion at 35 to 36 degrees C, only minor inactivation of all three viruses occurred. The k' values measured were 0.314 log10 unit/day for rotavirus, 0.475 log10 u...
متن کاملVirus Inactivation - Evaluation of Treatment Processes for Food and Biowaste
Animal by-products and manure contain valuable plant nutrients that could be recycled onto arable land, as fertiliser. If these materials contain pathogenic microorganisms, such as viruses, transmission to domestic animals, wildlife and the food chain could occur. Virus contamination of food may further occur during all production phases, from slaughter to packaging and distribution. To reduce ...
متن کاملThe Impact of Capsid Proteins on Virus Removal and Inactivation During Water Treatment Processes
This study examined the effect of the amino acid composition of protein capsids on virus inactivation using ultraviolet (UV) irradiation and titanium dioxide photocatalysis, and physical removal via enhanced coagulation using ferric chloride. Although genomic damage is likely more extensive than protein damage for viruses treated using UV, proteins are still substantially degraded. All amino ac...
متن کاملVirus inactivation mechanisms in human urine and fecal sludge
Water, sanitation and hygiene interventions are among the most significant health interventions addressing the worldwide burden of diarrheal disease and environmental enteropathy. Sanitizing human excreta and animal manure (HEAM) is a critical step in reducing the spread of disease and ensuring microbially safe reuse of waste materials. From the perspective of human excreta, it was recently est...
متن کاملEndocrine Disruptors in Wastewater and Sludge Treatment Processes
Background: Human immunodeficiency virus (HIV-1) preferentially selects tRNALys,3 as the primer for reverse transcription. HIV-1 can be forced to select alternative tRNAs through mutation in the primer-binding site (PBS) and a region upstream of the PBS designated as the A-loop. Alteration of the PBS and A-loop to be complementary to the 3' terminal nucleotides and anticodon of tRNAHis results ...
