摘要

Vegetative cells and spores of bacteria were treated by ozonation, by ozonation and sonication, by sonication, or by sonication during oxygenation. Vegetative cells and spores of Bacillus cereus and Clostridium perfringens were suspended in either phosphate buffered saline or secondary effluent for inactivation studies. Vegetative cells of B. cereus and C. perfringens were rapidly inactivated by ozone alone when suspended in phosphate buffered saline, while longer contact tines were required for inactivation when bacteria were suspended in secondary effluent. Simultaneous treatment by ozonation and sonication significantly reduced the time for complete inactivation in secondary effluent. Since sonication alone and sonication during oxygenation did not inactivate bacteria, the enhanced inactivation through simultaneous treatment with ozone and sonication is interpreted as a synergistic effect. Spores of B. cereus and C. perfringens were more resistant than vegetative cells and required longer contact times with ozone or ozone and sonication for complete inactivation when suspended in phosphate buffered saline or secondary effluent.
