Figure 1. SEM image showing the morphological characterization of the oxy-biodegradable plastic surface. (A) General view at the start of the experiment (T = 0); (B-D) Microbial colonization on the oxy-biodegradable bag substrate after 2 months of exposure (T = 1), where it is possible to see in detail the presence of diatom algae in different shapes (di), intense colonization by fungi (fu), and possible colonization by planktonic bacteria (arrow heads). (A-C) = 50 µm and (D) = 5 µm. SEM: Scanning electron microscopy.
