We developed a new microwave sterilization system that can rapidly raise filter temperature by microwave irradiation with a low microwave power. We prepared filters made of A 2 O 3 wool to trap microorganisms. The filters were coated with TiO 2 (anatase) by the sol-gel method before use. The filters were impregnated with each of two kinds of metals, Pt and Ag. We also prepared Tyranno-fiber (SiC continuous fiber containing small amounts of Ti, O) cloth and honeycomb SiC as filters. Two microorganisms, Escherichia coli and Bacillus subtilis were the targets in the present study. Cells of E. coli and B. subtilis loaded on the Ag-impregnated filter can be sterilized within 5 s by microwave irradiation. Tyranno-fiber cloth and honeycomb SiC were also effective for microwave sterilization. These results indicated that this technique enables rapid sterilization of E. coli and B. subtilis, and that microwave absorption materials, such as SiC and graphite, are effective for microwave sterilization filters.

Recently, airborne virus infections have emerged as some of the most challenging medical problems. To prevent the threat of infection, the processes of sterilization have been studied widely. Microwave sterilization has many advantages in comparison with conventional methods. It is able to raise the temperature of a material in a short time and selectively heat the material. This results in the reduction of usage and the rapid completion of sterilization. We developed a novel microwave sterilization system that can raise the temperature in quite a short time using a lower microwave power (100 W). Filters made with Kao wool (Al 2 O 3 ) were coated with TiO 2 (anatase) by sol-gel method and used to trap microorganisms. In addition, these filters were coated with Pt or Ag by impregnated method. We also prepared a Tyranno-fiber textile filter and a honeycomb SiC filter. Two microorganisms, Bacillus subtilis ATCC 9372 and Bacillus stearothermophilus ATCC 7953, were used in this experiment, where either microorganism was loaded onto a filter. After irradiation, filters loaded with B. subtilis and B. stearothermophilus were incubated for 48 h in a TSB medium (Bactoe Tryptic Soy Broth, Becton, Dickinson and company sparks, MD) at 37 and 56 8C, respectively. B. subtilis and B. stearothermophilus loaded on to Ag-impregnated filters were sterilized in 30 and 15 s, respectively. The Tyranno-fiber textile filter and the honeycomb SiC also filter showed effective microwave sterilization. These results showed that this system could sterilize B. subtilis and B. stearothermophilus in quite a short time and that microwave absorbable materials are effective as microwave sterilization filters. q
