(A) Evaluation of fumigation with plant products to improve microbial air quality. Graphical representation of the effect of traditional natural plant fumigating agents on microbiological air quality. The graph shows statistically significant (***p ≤ 0.001) improvement of microbiological air quality in terms of cfu/m3 when fumigated with natural plant products mentioned in the graph compared to control or baseline readings. The data represents the average of experiments performed thrice in triplicates. (B) SEM analysis of surface disinfection of fumigation with garlic peel. The SEM figure shows the effect of garlic peel fumigation on MRSA3 strain compared to control slide at 5000× magnification. (C) MATLAB correlation images of control and fumigated sample's SEM images are shown as labeled. The correlation values are represented through colors. The value of correlation increases from blue to red as shown in color bar scale. In control sample there are peaks almost everywhere while in treated sample the height of peaks reduces significantly and many regions peaks are disappeared completely (blue region) which indicates there is reduction in correlation factor. The mean correlation values are 0.0794 and 0.0329 for control and treated samples respectively. The decrease in mean correlation values confirms the distortion of bacteria in treated sample.
