A Review on Biodegradation of Plastics by Using Different Microorganisms

Due to the frequent utilization of plastic in households and companies, there is now more plastic in the environment.Every aspect of life uses plastics, which are man-made polymers.Plastics take between 20 and 500 years to naturally degrade.Landfilling, incineration, and recycling are the standard strategies used to regulate plastic waste.These techniques have been used to release dangerous chemicals into the environment during incineration and to less efficiently breakdown polymers.Therefore, the right approach is required to solve this issue.The greatest solution to this problem is biodegradation, or microbial decomposition.To breakdown plastics, microorganisms isolated from landfills, dumps, and soil are employed.Plastics, or polymers, are used by microorganisms as a source of carbon for their energy.Plastics were partially degraded by microbes in the past.In contrast to cremation and other risky chemical treatments, microbial decomposition is the best method.Microbial deterioration is less expensive and environmentally beneficial.Enzymes generated by microorganisms are utilized to break down polymers.Depolymerisation, mineralization, and assimilation are the three steps that make up the multi-step process of plastic breakdown.This article provides a summary of the various microorganisms, their propensity for degrading plastic, and the enzymes involved.
