This is a test that compares the inhibiting and suppressing effect of mold development with an antibacterial processing test piece and a non -processed test piece by measuring the amount of ATP before and after the culture by inoculating mold spore fluids and culturing the specimen. It can be implemented with water -absorbing specimen, such as textile products and paper. ISO13629-1 is a similar test method. * ATP is a substance in which living bacteria live. You can also arrange the test method. If you would like to consider changes such as test conditions, test bacteria species, sample properties, etc., please contact us. ■ Examination method ① Preparation of test spore solution In the provisions, it is prepared using 1/20 Sablo Dexstrose liquid medium. This nutritional conditions may be changed for the test purpose. * Use a single paraline solution. Unlike mold resistance tests, mixture cysts cannot be used. ② Preparation of sample Prepare a test sample and contrast sample cut to 0.20 ± 0.03g. * 1 Examination is performed using three samples each before and after the culture. * The sterilization of the sample is not done unless there is instructions. If you wish, please let me know. * The contrast sample refers to the same base as the test sample, which is not anti -carbed. * It is also possible to use a test piece that has been processed using a liquid or the like as a test sample and test it. If it is a cotton piece, we can prepare it. ③ Inoculation and culture of test spore fluids Test spore solution is inoculated into the sample and cultured at 25 ± 2 ° C for 42 ± 2 hours. ④ ATP amount measurement, evaluation ・ Use a special reagent to measure the amount of ATP in mold cells before and after culture. ・ Compare the ATP amount measurement result in the test sample and the contrasting sample, and evaluate the anti -mold effect. ■ Test bacterial species ・ ASPERGILLUSNIGERNBRC105649 (Kurokoujikabi) ・ PENICILLIUMCITRINUMNBRC6352 (Aokabi) ・ CLADOSPORIUMSPHAEROSPERMUMNBRC6348 or CladoSporiumCladoSPORIIDESNBRC6368 (black mold) ・ TRICHOPHYTONMENTAGROPHYTESNBRC32412 (Trichophyton) Such * Although it is selected from the above, it is possible to use other bacteria species other than the rules for test purposes. ■ The required amount of the sample If possible, prepare more than 10g per sample, including spares. If you cut to 0.20 ± 0.03g and prepare, you can test more smoothly. ■ Information necessary for the test implementation It is smooth if you can get the following information when quoting. ・ Number of specimens ・ Test bacteria species ・ Presentation of specimens corresponding to the contrast sample ・ Requested effects * (except for the Japanese Report) ・ How to make a test piece (when you want to test using a test piece processed with liquid or wet wipe) ・ Test conditions that you want to change (if any) * If you do not have any requests, only the Japanese report (the test method and test result (determination result of the test condition, ATP amount, anti -activity value), no image) will be on. ■ Delivery date 4 weeks ~ ※Please contact us for more information. ■ Expenses Please contact us.
