Abstract

The mass of air breathed by a human per day is equivalent to 10-times the mass of food consumed in that time. However, fundamental safety measures for atmospheric bacterial control have not yet been implemented. The purpose of our research is to develop a cell wall lytic filter using a cell wall lytic enzyme, which can inactivate the bacteria in air that cause infectious diseases by decomposing their cell envelope. In this study, the use of lytic enzyme mixture was suggested, including glycosidase, protease and lipase. The performance of the lytic enzyme mixture was evaluated using lysozyme, a typical lytic enzyme, as a control. The substrate that we used was Micrococcus luteus, a gram-positive bacteria. The experimental results showed that the use of the lytic enzyme mixture exhibited a lytic rate per hour that was 13 - 39% greater than the control. Furthermore, although there are some different phases during bacterium multiplication, the lytic rate per hour improved for all of the phases when the lytic enzyme mixture was used.
