https://www.selleckchem.com/products/azd0364.html Helminth eggs are among the most important biological contaminants in environmental engineering. They pose a significant health risk associated with poor sanitation, the use of contaminated water for irrigation, and the disposal of excreta or sludge to land. Helminths are parasitic worms transmitted to humans via their eggs, which is the infective stage of their life cycle. They are therefore relevant to public health and environmental fields due to their low infectious dose, their persistence in the environment (up to several years), and their high resistance to conventional disinfection processes. The evaluation of the efficiency of any process of inactivation, through the determination of the viability of these parasites, is fundamental, but the traditional incubation technique requires 20 days to determine both the viability and the infectivity of nematode eggs. However, the present study found that, using an inactivation process at a temperature of 60 °C for 1 hour and incubation at 28 °C and 34 °C, the absence of division of the nucleus of eggs of species from two genera, Ascaris lumbricoides and Toxocara canis, showed them to be inactivated following only 48 hours of incubation. Similar inactivation results were observed using an automatic system as long as the eggs were inactivated. The minimum time required to evaluate the inactivation of nematode eggs through the incubation technique was 48 hours.Anaerobic co-digestion of sewage sludge with organic wastes has recently gained attention in small facilities. For small facilities, high solids sludge is suitable for transportation to a centralized co-digester, and direct utilization of the digested sludge as liquid fertilizer is recommended. Effects of high solid and hyperthermophilic pretreatment (80 °C, 24 hr) on anaerobic digestion at low temperatures and utilization as fertilizer are investigated by anaerobic/aerobic digestion and paddy soil incubation exper
