Summary of "Removing Escherichia coli from water using zinc oxide-coated zeolite."

The removal of Escherichia coli (E. coli) from water by zinc oxide-coated zeolite (ZOCZ) and ZOCZ's antibacterial properties were examined in laboratory experiments using plate counting method and tests of cell apoptosis. Batch experiments showed that ZOCZ has a maximum removal capacity for E. coli of about 4.34 × 10 CFU g at 25 °C. Element mappings confirm that zinc ions accumulate in the E. coli cells causing cell death. Pseudo-second-order kinetics and Freundlich isotherms were found to best describe the removal of E. coli, suggesting that a multilayer of E. coli cells forms on the surface of ZOCZ particles.

Medical and Biotech [MESH] Definitions

Strains of ESCHERICHIA COLI that are a subgroup of SHIGA-TOXIGENIC ESCHERICHIA COLI. They cause non-bloody and bloody DIARRHEA; HEMOLYTIC UREMIC SYNDROME; and hemorrhagic COLITIS. An important member of this subgroup is ESCHERICHIA COLI O157-H7.

Strains of Escherichia coli that possess virulence traits which allow them to invade, colonize, and induce disease in tissues outside of the GASTROINTESTINAL TRACT. They are a cause of URINARY TRACT INFECTIONS (UROPATHOGENIC ESCHERICHIA COLI); neonatal MENINGITIS; SEPSIS; PNEUMONIA; and SURGICAL WOUND INFECTION.

An enterohemorrhagic Escherichia coli of the O subfamily that can cause severe FOODBORNE DISEASE. The H4 serotype strain produces SHIGA TOXINS and has been linked to human disease outbreaks, including some cases of HEMOLYTIC-UREMIC SYNDROME, resulting from contamination of foods by feces containing E. coli O104.

A species of gram-negative, rod-shaped bacteria belonging to the K serogroup of ESCHERICHIA COLI. It lives as a harmless inhabitant of the human LARGE INTESTINE and is widely used in medical and GENETIC RESEARCH.

A verocytotoxin-producing serogroup belonging to the O subfamily of Escherichia coli which has been shown to cause severe food-borne disease. A strain from this serogroup, serotype H7, which produces SHIGA TOXINS, has been linked to human disease outbreaks resulting from contamination of foods by E. coli O157 from bovine origin.
