Quest for Isolation and Identification of Plastic Degradingmicroorganisms: a Molecularapproach
AI summary Read the abstract
Researchers isolated soil microorganisms and tested their ability to biodegrade polyethylene and PVC plastics in vitro over one month, identifying both gram-positive and gram-negative bacterial species with degradation capability. The study highlights microbial biodegradation as a low-cost, eco-friendly strategy to reduce plastic waste accumulation in the environment.
Microorganisms havea very essential role in the biological breakdown of various organic matter in the natural environment, this process is known as biodegradation. Polyethylene waste and plastics from synthetic materials accumulate in the environment and represent a growing ecological threat. Biotic and abiotic methods have been used to turn polymers into monomers. This issue might be resolved by powerful microbial strains (robust) and the biodegradation of this plastic trash. In this study, in vitro, the biodegradation of polyethylene and PVC tapes was analyzed using microorganisms isolated from the soil after an incubation period of one month. Microbial species associated with degradation ability were identified as Gram-positive bacteria and Gram-negative bacteria. In the future, microbial-friendly plastics are safe for the environment and can reduce plastic waste on the environment Further research is underway and it will have good applications in the future due to its low cost and eco-friendly properties.

Isolation, Screening and Characterization of Plastic-Degrading Bacteria From Soil for PWM
AI summary Read the abstract
Scientists isolated bacteria from soil near garbage sites and identified strains capable of degrading plastic materials, with scanning electron microscopy revealing physical damage — holes and cracks — to plastic surfaces after bacterial exposure within 30 days. The study contributes to the search for soil microbes that could be harnessed for biological plastic waste management. Biodegradation by indigenous soil bacteria could offer a more environmentally friendly alternative to landfilling or incineration of plastic waste.
