Polyhydroxyalkanoates (PHAs) are biobased and biodegradable polymers that offer a sustainable alternative to conventional plastics, addressing the escalating concerns over plastic pollution. While their environmental advantages well-documented, efficient degradation of PHAs in natural engineered environments remains critical component lifecycle. This review provides comprehensive overview PHA-degrading bacteria isolated from diverse ecosystems highlights pivotal role PHA depolymerases achieving circularity. Microbial adaptation conditions, such as extreme temperatures, salinity, pH, significantly influences enzymes properties, including stability, activity, substrate specificity enzymes. These adaptations often enhance enzyme, performance, enabling functionality under challenging conditions. Consequently, extremophilic microorganisms invaluable resources for discovering engineering robust industrial applications. underscores urgent need further research improve ecological economic sustainability waste management.

Abstract Background Plastic is widely utilized in packaging, frameworks, and as coverings material. Its overconsumption slow degradation, pose threats to ecosystems due its toxic effects. While polyhydroxyalkanoates (PHA) offer a sustainable alternative petroleum-based plastics, their production costs present significant obstacles global adoption. On the other side, multitude of household industrial activities generate substantial volumes wastewater containing both organic inorganic contaminants. This not only poses threat but also presents opportunities get benefits from circular economy. Main body abstract Production bioplastics may be improved by using nutrients minerals feedstock for microbial fermentation. Strategies like feast-famine culture, mixed-consortia integrated processes have been developed PHA highly polluted with high loads. Various process parameters loading rate, content (volatile fatty acids), dissolved oxygen, operating pH, temperature critical roles accumulation biomass. Research advances are going on downstream recovery utilizing combination physical chemical (halogenated solvents, surfactants, green solvents) methods. review highlights recent developments upcycling resources into PHA, encompassing various strategies, processing methodologies, techno-economic analyses. Short conclusion Organic carbon nitrogen promising, cost-effective source producing bioplastic. Previous attempts focused enhancing productivity through optimizing culture systems growth conditions. However, despite technological progress, challenges persist, such low productivity, intricate processing, scalability issues, properties resulting PHA. Graphical

Industrial evolution and agricultural expansion, explained by continuing population growth, have rendered enormous problems for the world throughout past few decades, primarily because of waste generation. To reduce environmental impact dependence on fossil fuels, scientists explored replacing synthetic polymers with environmentally friendly sustainable alternatives in many emergent applications. In this regard, microbial biopolymers gained special attention. Many originating from various strains bacteria, fungi, algae been reported their possible applications increased rapidly. This review focuses wide range biopolymers, characteristics, factors influencing production. The present study also describes biopolymers. use these is very attractive as a value-added approach to wastewater treatment. By acting adsorbents, coagulants, flocculants well filters membrane processes, shine promising solutions beyond conventional methods. They can be integrated into stages treatment process, further enhancing efficiency Microbial biopolymer bioremediation soil stabilization are reviewed. Several studies demonstrated strong potential improvement due ability minimize permeability, eliminate heavy metals, stabilize soil, limit erosion. Challenges related scaling up downstream processing its future perspectives applications, discussed.
