Investigation of surface topography and roughness parameters by AFM. Topography of plastic samples (A) control (untreated) and treated with (B) Stenotrophomonas sp. P2 and (C) Achromobacter sp DF22 after 45 days of incubation. (D) In comparison to Control (Black), increase in roughness parameters [average roughness (Ra), root mean square roughness (Rq), average height (Rz), maximum peak height (Rp), and maximum valley depth (Rv)] was observed for the LDPE films treated with Stenotrophomonas sp. P2 (orange) and Achromobacter sp. DF22 (brown).
