Fig. 1From: A UV-LED module that is highly effective at inactivating human coronaviruses and HIV-1Kinetic analysis of Bacillus pumilus growth after UV exposure. Stainless steel discs inoculated with Bacillus pumilus spores were exposed to UV for the specified times after which the discs were used to inoculate liquid cultures. After seven days in culture, optical density (OD, 600 nm) readings were taken. Log-reduction was calculated by taking the base-10 logarithm of the quotient (N0/N), where N0 and N represent the untreated and irradiated discs, respectively. Data are mean ± SD of four experimental replicates across two independent experiments. OD measurements were done in triplicatesBack to article page
