Test method

Bacterial strain:Escherichia coli NBRC 3972、Staphylococcus aureus ATCC
6538
Culture medium:SCD Broth Soya BrothSCD Soybean Casein Digest Agar
Each test strain was grown in SDC bouillon medium and then transferred
to SDC agar medium and incubated at 35 °C for 24 hours.That bacteria
were suspended in sterilized saline solution to make the test solution.
Each test bacterial liquid prepared was plated on SDC agar medium.
These agar media were irradiated with JOKIN99 M-560 for 10 and 20 minof UVC .Untreated ones were used as controls (0 min), and these wereincubated at 35°
C for 24 hours, after which the colonies were checked.
In order to conﬁrm the number of bacteria in the inoculated test solution,
the SDC agar medium was inoculated with a suitable dilution of sterile
saline solution, incubated at 35 °C for 24 hours, and the colonies werecounted.

Test results

because of long-term irradiation of lowpower-UVC rays.
And, equipped with a 20-minute auto-oﬀ function.

Figures 1-2 below. The number of colonies counted was as shown in thetable below. The number of colonies in the test solution inoculated at theirradiation time of 0 minutes is shown as the number of colonies.
