Biodegradation is an advanced method for reducing plastic waste in the environment, involving participation of microbial communities with plastic-degrading properties. Our study presents a novel halophilic community isolated from plastic-contaminated region Burgas Lake, Bulgaria. In medium containing 15% sodium chloride, can degrade significant amount polycaprolactone (PCL) as sole carbon source, well plastics polystyrene (PS) and polypropylene (PP), albeit to lesser extent. The showed high hydrophobicity ability form biofilm on PCL beads, esterase activity biodegradation capacity, demonstrated by measuring weight material after cultivation 4 8 weeks. Moreover, scanning electron microscopy (SEM) analysis revealed visible cracks, craters, holes surface polymer particles. metagenomic that Halomonas profundus dominated proportion 95.13%, followed Alloalcanivorax venustensis (2.73%), Chromohalobacter marismortui (0.72%), caseinilytica (0.78%). However, most species were not previously known PCL-degrading. Thus, studying diversity halophile significantly improve our fundamental understanding clarify their potential applications environmental water–plastic remediation.

Polyethylene terephthalate (PET), a widely used synthetic polymer in daily life, has become major source of post-consumer waste due to its complex molecular structure and resistance natural degradation, which posed significant threat the global ecological environment human health. Current PET-processing methods include physical, chemical, biological approaches, however each have their limitations. Given that numerous microbial strains exhibit remarkable capacity degrade plastic materials, degradation PET emerged as highly promising alternative. This approach not only offers possibility converting into valuable resources but also contributes advancement circular economy. Therefore this review, it is mainly focused on cutting-edge technologies key role specific such Ideonella sakaiensis 201-F6, can efficiently assimilate PET. Particularly noteworthy are catalytic enzymes related metabolism PET, been emphasized sustainable eco-friendly strategy for recycling within framework Furthermore, study elucidates innovative utilization degraded materials feedstock production high-value chemicals, highlighting path forward management waste.
