Abstract The perpetual disposal of plastic waste, combined with ineffective waste management strategies, has resulted in widespread environmental pollution. Microbial biodegradation represents an emerging solution to this problem. However, studies tend overlook the fundamental prerequisite initial surface colonization via biofilm formation. This study had two independent but connected aims relating by microorganisms: enhance formation known degraders, translational potential for improved degradation, and isolate microorganisms from microplastic contaminated environments ability colonize surfaces. Planktonic responses diverse carbon energy sources were investigated over 7 days, using Bacillus subtilis 168, Fusarium solani (Martius) Saccardo, Ideonella sakaiensis 201-F6, Pseudomonas putida KT2440, Rhodococcus ruber C208. enabled optimal conditions each strain be determined. In parallel, samples containing synthetic or natural polymeric substances (anaerobic digestate, landfill leachate, compost) incubated polyethylene terephthalate films, capable colonizing their yielded eight bacterial isolates three genera: Bacillus, Lysinibacillus, Proteus. These genera contain species that have been shown degrade plastics other recalcitrant polymers, demonstrating success our approach. also suggests discrete types may create different ecological niches which can exploited unique colonizers. Our findings underscore importance considering microbial biofilms context biodegradation.
