Abstract Recently, there has been increased attention to hydrocarbonoclastic bacteria in the plastisphere. One particular genus, Alcanivorax , is reported biodegradation of several polymers literature. In this study, we further explored role early colonization poly(3‐hydroxybutyrate‐co‐3‐hydroxyhexanoate) (PHBH), nylon 6/69, and a novel plastic B4PF01. Starting from enrichments one‐year experiment with maximum relative abundance 58.8% two parallel experiments were set up. followed growth activity during first 21 days incubations, other same parameters on different material fractions plastics, such as leachables pure polymer. For all types, highest microbial was associated total plastics compared fractions. A 62.7% 6/69‐enriched community observed. This, combined data activity, suggests that 6/69 potentially degraded by genus. Two isolates obtained, closely related A. borkumensis SK2 sp. DG881. The axenic cultures resemble their community. conclusion, study contributes knowledge plastic‐enriched communities.

Abstract The unprecedented surge in the demand for personal protective equipment (PPE) worldwide during covid pandemic resulted a significant increase PPE consumption and subsequent waste generation. Despite importance of PPE, its widespread usage disposal have sparked worries about environmental impact long-term sustainability. increasing awareness challenges, resource scarcity, urgent need to mitigate climate change necessitates paradigm shift product design, manufacturing process, management PPE. To address these challenges sustainable future, development degradable polymers natural fibers offers promising alternative traditional plastics. Additionally, recycling upcycling methods can convert into valuable alternate products or energy sources, thereby reducing their impact. Better systems, comprehensive policy frameworks, international collaborations are essential effective promotion practices. collaborative efforts across governments, manufacturers, research institutions, authorities crucial transitioning more industry circular economy, ultimately benefiting both environment society.

Despite the promise of a reduced environmental impact, bioplastics are subjected to dispersion and accumulation similarly traditional plastics, especially in marine coastal environments. The impact is attracting increasing attention due growing market demand. ability supralittoral amphipod Talitrus saltator ingest survive on pristine starch-based bioplastic has already been assessed. However, involvement gut microbiota this key species making dietary supplement, remains unknown. In study, we investigated modification T. following ingestion effect change their chemical composition. Groups adult amphipods were fed with: 1 - two different kinds bioplastic; 2 50 %/50 % chitosan-starch mixture; 3 paper dry-fish-food. Freshly collected, unfed individuals used as control group. Faecal pellets from collected characterized using ATR-FTIR spectroscopy. DNA was extracted samples for metagenomic analysis. Spectroscopic investigation suggested partial digestion polysaccharide components experimental polymeric materials. analysis revealed that feeding induced sandhopper's microbial communities, shifting abundance specific genera present gut, towards bacterial associated with plastic/bioplastic degradation, groups bioplastics. Overall, our results highlight saltator's modification, providing new insights into potential role consortia sandhoppers management.

Since the mid-20th century, quantity of microplastics (MPs) has increased significantly, becoming a persistent environmental pollutant widely distributed in global water bodies, soils, and atmosphere. While plastic materials have brought significant convenience to daily life, MPs resulting from their degradation pose increasing threats ecosystems human health. This comprehensive review examines sources, migration pathways, ecological impacts MPs, critically evaluates current separation techniques physical, chemical, biological perspectives. In particular, numerical simulations hydrocyclone technique reveal its unique flow characteristics, including turbulent velocity gradients axial pressure differences, with efficiency up 93%. offers advantages such as high efficiency, low energy consumption, friendliness. response growing microplastic pollution issue, this emphasizes that development future should prioritize sustainability, compatibility. Continued research field will provide theoretical support for optimizing control technologies contribute achieving protection sustainable goals.

Although massive studies have investigated the spatiotemporally occurring marine plastisphere, a new microbial ecosystem colonizing surfaces of plastics, resulting biofragmentation process and impacts plastics on biogeochemical cycles remain largely unknown. Here, we leverage synchrotron-based Fourier transform infrared spectromicroscopy (FTIR mapping) metagenomic sequencing to explore independent microcosms amended with petroleum-based polyethylene (PE) biobased polyhydroxybutyrate (PHB) plastic films. FTIR mapping results demonstrate unequal fragmentation scenarios by which PE rarely releases oxidized fragments while PHB disintegrates quickly, gradually forming composed extracellular polymeric substances resembling Metagenomic analysis shows critical role hydrocarbonoclastic lineages in biodegradation two fatty acid degradation pathway, where host different trajectories between plastisphere (dominated

Microplastics (MPs) and antibiotics (ATs) are emerging contaminants with recognized negative effects on marine ecosystems. MPs can adsorb transport ATs, posing combined toxic to organisms. Despite growing concerns, research remains limited the MP-AT co-contaminants in tidal zones, which home numerous aquatic species represent a particularly susceptible ecosystem. This study used polyethylene (PE) tetracycline (TC) investigate influence under various conditions, including sediment sizes, cycles, MP of zones using cycle simulation system, was designed replicate dynamics provide insights into movement behavior contaminants. It observed that sediments exist three distinct states. Smaller (State 1) pass through sand pores widely distributed upper layers, whereas larger 2) concentrate layers 1-5 due size limitations. Agglomerated 3), unable pores, accumulate at bottom. Tidal cycles enhance co-contaminant retention, while (125-212 μm) limitedly affects their distribution. played crucial role, settling smaller remaining more dispersed. These findings emphasize importance affecting contaminant environments. Results from this will contribute development models help predict long-term environmental impact co-contaminants.
