    • Biodegradable plastics in Mediterranean coastal environments feature contrasting microbial succession 

      de Vogel, Fons A.; Goudriaan, Maaike; Zettler, Erik R.; Niemann, Helge; Eich, Andreas; Weber, Miriam; Lott, Christian; Amaral-Zettler, Linda A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-04-08)
      Plastic pollution of the ocean is a top environmental concern. Biodegradable plastics present a potential “solution” in combating the accumulation of plastic pollution, and their production is currently increasing. While these polymers will contribute to the future plastic marine debris budget, very little is known still about the behavior of biodegradable plastics in different natural environments. ...

    • Plastic photodegradation under simulated marine conditions 

      Delre, Annalisa; Goudriaan, Maaike; Morales, Victor Hernando; Vaksmaa, Annika; Rachel Tintswalo, Ndhlovu; Marianne, Baas; Keijzer, Edwin; de Groot, Tim; Zeghal, Emna; Egger, Matthias; Röckmann, Thomas; Niemann, Helge (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-12)
      Ocean plastic pollution is a problem of increasing magnitude; yet, the amount of plastic at the sea surface is much lower than expected. Solar ultraviolet (UV) radiation can induce photodegradation, but its importance in determining the longevity of floating plastic remains unconstrained. Here, we measured photodegradation rates of different plastic types slightly larger than microplastics (virgin ...

    • A stable isotope assay with 13C-labeled polyethylene to investigate plastic mineralization mediated by Rhodococcus ruber 

      Goudriaan, Maaike; Morales, Victor Hernando; van der Meer, Marcel T.J.; Mets, Anchelique; Ndhlovu, Rachel T.; van Heerwaarden, Johan; Simon, Sina; Heuer, Verena B.; Hinrichs, Kai-Uwe; Niemann, Helge (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-30)
      Methods that unambiguously prove microbial plastic degradation and allow for quantification of degradation rates are necessary to constrain the influence of microbial degradation on the marine plastic budget. We developed an assay based on stable isotope tracer techniques to determine microbial plastic mineralization rates in liquid medium on a lab scale. For the experiments, <sup>13</sup>C-labeled ...
