(A) Clear zone test for 14 days on solid medium containing PBS plastic emulsion in TSB. (B) GC-MS results for degradation yield of PBS according to degradation time (days 0, 3, 5, and 7). (C) The visual appearance of PBS films undergoes alterations as a result of degradation. Changes in the degradation of PBS films are observed at different incubation periods (0, 3, 5, and 7 days). Representative images of surface changes observed by (D) scanning electron microscopy (SEM).
