14.4 Conclusion and Future Recommendations
This chapter has discussed extensively the practical application of beneficial microorganism that could degrade plastic and synthetic polymers. It was established in this
chapter that microbial degradation of plastic has several merits when compared to
physical and synthetic approaches. Furthermore, the application of engineered
biodegradation pathways should be encourage to enhance the biodegradability
capability of these potential strains. The modes of action through which these strain
break down the surface of the polymer were also discussed in details. The application of techniques such as atomic force microscopy and scanning electron microscopy was also elucidated for the validation of the role of these biodegradative strains
most especially their degradative role on the surface of these plastics. The application of Fourier transform infrared spectroscopy for the detection and monitoring of
the biodegradation of these plastic was also highlighted in detail. This chapter also
established that the application of potential strains isolated from landfill environment
could be utilized for the biodegradation of plastic wastes in a controlled environment
such as landfill or in dumped soil.
