Identification of the best-performing novel microbial strains from naturally-aged graffiti for biocleaning research

Microorganisms that can act as biocleaning agents potentially be isolated from existing graffiti. In this study, a total of 30 different isolates bacteria, fungi and yeasts were obtained black, blue, red silver graffiti coatings exposed outdoors conditions for 10 years. An additional strain was samples black powdered under laboratory 5 Each the most prolific sources (i.e. graffiti) evaluated alone in combination with Tween® 20, to determine their potential agents, test tube assays. Two strains coating (identified Candida parapsilosis) one powered Rhodococcus erythropolis) performed best alone. The quantity live cells throughout trials biofilm formation indicated both able utilize paint substrate. When microorganisms combined increased notably incubation time, turbidity discoloration observed. Infrared spectroscopic examination revealed R. erythropolis alone, while addition 20 C. parapsilosis enhanced oxidative degradation
