Fig. 2 — Background level (BG) bacteria colonies and residual bacteria colonies in winter and summer periods for two application modes (SM and TM), two disinfectants (ClO₂ and WAHW) and two application rooms (SR and DR). Note that for each disinfection combination (CSR, CDR, WSR and WDR), significant differences (p < 0.05) among BG, SM and TM are annotated with different letters (a–c) according to MANOVA and Duncan's tests. Note also that the bars represent the mean ± SD. CSR (ClO₂ used in SR), CDR (ClO₂ used in DR), WSR (WAHW used in SR) and WDR (WAHW used in SR)
