“…It follows that these microorganisms would have different optimal growth conditions, changing based on the biogeochemical setting. Understanding of marine microbe-plastic interactions stems from studies of microbes and plastics in terrestrial environments (Table 3) (Cosgrove et al 2007;Yoshida and Hiraga 2016;Auta et al 2017). Of particular interest is Ideonella sakaiensis, a novel bacterium isolated from a polyethylene terephthalate (PET) bottling plant landfill (Yoshida et al 2016).…”

Microorganisms drive the biogeochemical cycles that link abiotic and biotic processes in the aqueous environment and are intricately associated with plastic debris. The detection of microplastics in water and sediment introduces new concerns as small particle size allows for yet unconsidered pathways for plastics in the food web and element cycles. In this review, we present current knowledge of microbe-plastic interactions and summarize the potential impact of biogeochemical processes on plastic distribution, cycling, transport, and sedimentation. We explore how microbe-plastic interactions influence the exposure of consumers to plastics and plastic degradation products. Key methods used to elucidate biofilm development, microbial biodegradation, and plastic detection in the aqueous environment are discussed. Finally, we comment on potential future questions and research directions needed to further define the role of microorganisms in the environmental fate of microplastics.

“…From an evolutionary point of view, the time span of plastic production is rather short and therefore, only a very limited evolutionary pressure for organisms to evolve enzymes for efficient plastic degradation has occurred (Hopewell & Kosior, ; Tokiwa, Ugwu, & Aiba, ). However, several plastic degrading organisms are reported to depolymerize for instance polyethylene terephthalate (PET), polypropylene (PP), and polystyrene (PS; Auta, Emenike, & Fauziah, ; Cacciari, Zirletta, Vinciguerra, & Giovannozzi, ; Pathak & Navneet, ; Shah, Hameed, & Ahmed, ). To ensure efficient degradation of plastics, the organisms have to be in close proximity or to attach to the targeted polymer surfaces.…”

Accumulation of plastics in the environment became a geological indicator of the Anthropocene era. An effective reduction of long-lasting plastics requires a treatment with micro-organisms that release polymer-degrading enzymes. Polymer binding peptides function as adhesion promoters and enable a targeted binding of whole cells to polymer surfaces. An esterase A-based Escherichia coli cell surface display screening system was developed, that enabled directed evolution of polymer binding peptides for improved binding strength to polymers. The E. coli cell surface screening system facilitates an enrichment of improved binding peptides from a culture broth through immobilization of whole cells on polymer beads. The polypropylene (PP)-binding peptide liquid chromatography peak I (LCI) was simultaneously saturated at five positions (Y29, D31, G35, E42, and D45; 3.2 million variants) and screened for improved PP-binding in the presence of the anionic surfactant sodium dodecylbenzenesulfonate (LAS; 0.25 mM). The cell surface system enabled efficient screening of the generated LCI diversity (in total 10 million clones were screened). Characterization of identified LCI binders revealed an up to 12-fold improvement (eGFP-LCI-CSD-3: E42V/D45H) in PP-binding strength in the presence of the surfactant LAS (0.125 mM). The latter represents a first whole cell display screening system to improve adhesion peptides which can be used to direct and to immobilize organisms specifically to polymer surfaces (e.g., PP) and novel applications (e.g., in targeted plastic degradation).

“…Besides that, the extensive use of plastic contributes to negative impacts on the environment as it could create plastic pollution, deterioration of human health, disrupting the aquatic system, flora and fauna. The impact of plastic waste will disturb the water environments such as lakes, rivers, and ponds if plastic waste is not well managed [1]. The micro-plastic has been considered as a crucial issue in the world that cause environmental contamination.…”

“…Primary micro-plastic is made purposely for manufactures specific in domestic and industrial application comprise with raw polystyrene (PS), polyethylene (PE), polypropylene (PP) and polyethylene terephthalate particle (PET) [7]. The primary micro-plastic commonly used for cosmetics, cleanser in personal care product, toothpaste, cleaning product, textiles, clothing, and plastic industries [1]. This primary micro-plastic can enter the aquatic system through the household sewage discharge, industrial effluent, human activities and treatment plant [4].…”

Plastic waste has become a sensitive issue in the world since this material needs a longer time to degrade. This material will take a month to a thousand years to decompose. Thus, would contribute to the environment pollution, which will affect human health and aquatic life. This research study focused on the biodegradation process of micro-plastic (PE, PP, PET and PS) in the batch culture system using a colony of bacteria obtained from leachate in Ayer Hitam Landfill, Puchong. After the batch experiment of micro-plastic degradation, percentage removal of ammonia-nitrogen, chemical structure and percentage weight loss were examined and evaluated. Succeeding through the incubation of micro-plastic in batch culture for fourteen (14) days period, biodegradation was verified by the estimation of the dry weight loss. From the result obtained, dry weight loss of polyethylene (PE) is the highest (3.46%) in 14 days and polyethylene (PE) shows the greater removal of ammonia nitrogen (NH3 -N) (44.17%). Besides that, polystyrene (PS) micro-plastic showed a significant change in chemical structural which was obtained by Fourier Transform Infrared (FTIR). Here, the new absorption peak C=O (aldehydes) was present in PS micro-plastic. Furthermore, PS micro-plastic has a high percentage mass loss in the second stage of thermal degradation by Thermogravimetric (TGA) analysis. It can be concluded that incubation time is needed to optimize the micro-plastic in the biodegradation process.
