Can fungi contribute to decompose of plastic?

Plastic (polymer) is not only an inexpensive and convenient material in the living environment, it is also an essential agricultural material in agriculture. After the farming is over, plastics waste does not decompose naturally in the soil, causing obstacles to growth in crops and pollution of soil. Recently, interest in the decomposition of polymers using microorganisms continues to increase. In this study, we intend to investigate the distribution of microorganisms that are parasitic on both soil and polymer through NGS (Next-Generation Sequencing) analysis. Base on the 1,485,129 sequences for the classification, the OTU (Operational Taxonomic Unit) distribution showed the 763 bacteria strains and 522 fungi strains. Mortierella sp. is a dominant species in both polymer and soil. Plectosphaerella sp. and Fusarium sp., known as decomposing the polymer, are existed on polymer and soil. The result suggests that 1) Based on NGS data, it is possible to identify microorganisms that are capable of polymer decomposition. 2) Microorganisms analyzed from soil and polymer can be isolated. 3) We will analyze to characteristics of polymer decomposes microorganisms by using microorganisms of the isolate from the soil and plastic waste. These results will provide a new experimental field of perspective for bioremediation.
