Abstract
Paint is mainly used for two purposes like decoration and protection but it is the main source of volatile organic compounds which may cause short or long term impacts on environment, which also leads to health problems such as nerve and kidney damage. Ozone is formed when nitrogen oxides, carbon monoxide, and VOCs react in atmosphere in the presence of sunlight these chemicals cause respiratory problems and carcinogenic. Bacterial organisms such as Pseudomonas spp, Bacillus spp and Staphylococcus spp were isolated from the paint flakes. Shake flask experiment was carried out to assess the paint degradation ability of these microbes. The experiment was carried out for 14 days under 37°C with continuous shaking to provide good aeration to for the degradation and growth of microorganism. Characterization of paint sample before and after treatment were studied using FT IR and SEM analysis. FTIR analysis reflected a shift in the functional groups, due to degradation activity of microbes. SEM analysis clearly showed the adherence and bacterial growth on paint flakes. The treated samples evidently showed distorted / ruptured surface when compared to the untreated samples which had intact structures of the paint compounds.
