Abstract
Pseudomonas sp. isolated from soil, are bioremediating microorganisms that are capable of degrading various types of plastics. Polyphenylene sulfide (PPS) has the most excellent structural stability among general plastics and thus is extremely difficult to break down using physical or chemical methods. This study demonstrates the efficient biodegradation of PPS by Pseudomonas sp., which exists in the gut of superworms. Compared with the conventional film-type of plastic, the degradation efficiencies to the bead form of plastic were significantly improved and thus the biodegradation time was dramatically shortened. Therefore, instead of film-type plastics, we used 300 μm diameter plastic beads for the measurement of Pseudomonas sp.-mediated biodegradation of PPS during a 10-day period. This method not only can be used for comparison and verification of the biodegradation efficiency of different types of plastics within a short reaction time of 10 days, but also provides the possibility to develop a new and more efficient screening system to rapidly identify the most efficient species of bacteria for the biodegradation of various types of plastics. © 2020 Elsevier B.V.
