AB  - This study examines the microbial colonization characteristics of microplastics 
      (MPs) in wastewater treatment plants (WWTPs), focusing on polymer types 
      (High-Density Polyethylene (HDPE) and Polyethylene Terephthalate (PET)) and 
      various stages of wastewater treatments. Through individual and sequential 
      deployment approaches, the research aimed to identify the determinants of 
      bacterial colonization on MPs, whether they were introduced at each stage of 
      treatment individually or in sequence from primary to tertiary stages. The study 
      revealed that the stage of wastewater treatment profoundly influenced bacterial 
      colonization on the polymer types MPs, with bacterial attachment being largely 
      niche-specific. HDPE showed increased sensitivity to wastewater composition, 
      leading to selective biofilm formation. For instance, in HDPE, Firmicutes 
      accounted for 25.1 +/- 0.04 % during primary treatment, while Alphaproteobacteria 
      increased significantly in the tertiary treatment to 19.8 +/- 0.1 %. Conversely, 
      PET exhibited a stochastic pattern of bacterial colonization due to differences 
      in surface hydrophilicity. Additionally, in sequential deployments, a notable 
      shift towards stochastic bacterial attachment on MPs, particularly with HDPE was 
      observed. The Shannon diversity values for MP biofilms were consistently higher 
      than those for wastewater across all stages, with PET showing an increase in 
      diversity in sequential deployments (Shannon diversity: 5.01 +/- 0.03 for tertiary 
      stage). These findings highlight the critical role of MPs as carriers of diverse 
      bacteria, emphasizing the necessity for strategies to mitigate their impact in 
      WWTPs. This study presents a significant advancement in our understanding of the 
      interactions between MPs and microbial populations in WWTP environments.
