Biodegradation of Typical Plastics: From Microbial Diversity to Metabolic Mechanisms

International Journal of Molecular Sciences, Год журнала: 2024, Номер 25(1), С. 593 - 593

Plastic production has increased dramatically, leading to accumulated plastic waste in the ocean. Marine plastics can be broken down into microplastics (<5 mm) by sunlight, machinery, and pressure. The accumulation of organisms release additives adversely affect health marine organisms. Biodegradation is one way address pollution an environmentally friendly manner. microorganisms more adapted fluctuating environmental conditions such as salinity, temperature, pH, pressure compared with terrestrial microorganisms, providing new opportunities pollution. Pseudomonadota (Proteobacteria), Bacteroidota (Bacteroidetes), Bacillota (Firmicutes), Cyanobacteria were frequently found on biofilms may degrade plastics. Currently, diverse plastic-degrading bacteria are being isolated from environments offshore deep oceanic waters, especially Pseudomonas spp. Bacillus Alcanivoras Actinomycetes. Some fungi algae have also been revealed degraders. In this review, we focused advances biodegradation their enzymes (esterase, cutinase, laccase, etc.) involved process polyethylene terephthalate (PET), polystyrene (PS), (PE), polyvinyl chloride (PVC), polypropylene (PP) highlighted need study sea.

Water Quality Impact on Fish Behavior: A Review From an Aquaculture Perspective

Reviews in Aquaculture, Год журнала: 2024, Номер 17(1)

Опубликована: Ноя. 6, 2024

ABSTRACT Changes in water quality significantly shape fish behavior, a crucial index reflecting the growth and welfare status of fish. Given centrality this relationship to aquaculture practices, comprehensive understanding how dynamics influence behavior is imperative. While there have been some summaries effects parameters on physiology growth, few reviews their reported yet. This article several which are great concern from multiple facets actual production, including physical (water temperature turbidity), chemical (dissolved oxygen, salinity, pH, inorganic nitrogen), pollutants (microplastics crude oil), gained increasing attention researchers practitioners over past decades. Variations these can exert profound physiology, metabolism, internal tissues organs, sensory perception, influences behaviors such as swimming, schooling, feeding, predation, anti‐predation, aggression, courtship, well adaptive stress‐related exploration, avoidance response, anxiety‐like behavior. By synthesizing behavioral changes caused by specific parameters, review aims provide strong support for further quality‐related research, thereby fostering environments conducive both productivity.

Microplastic burden in marine benthic invertebrates depends on species traits and feeding ecology within biogeographical provinces

Nature Communications, Год журнала: 2023, Номер 14(1)

Опубликована: Дек. 4, 2023

Abstract The microplastic body burden of marine animals is often assumed to reflect levels environmental contamination, yet variations in feeding ecology and regional trait expression could also affect a species’ risk contaminant uptake. Here, we explore the global inventory individual for invertebrate species inhabiting sediments across 16 biogeographic provinces. We show that benthic invertebrates cannot be fully explained by absolute contamination environment, because interspecific differences behaviour strongly determine Our analyses indicate degree species-specific particle selectivity; likely associated with biology. Highest occurs Yellow Mediterranean Seas and, contrary expectation, amongst omnivores, predators, deposit feeders rather than suspension species. findings highlight inadequacy uptake assessments based on inventories alone, need understand how covary contamination.

Microplastic ingestion by deep‐pelagic crustaceans and fishes

Limnology and Oceanography, Год журнала: 2023, Номер 68(7), С. 1595 - 1610

Опубликована: Май 15, 2023

Abstract A size‐selective loss of smaller microplastics (< 1 mm) from surface pelagic waters has been reported, yet few surveys have studied biological ingestion by deep‐pelagic organisms as a sink for the “missing” plastic. Here, 557 individuals representing 35 species vertically migrating and nonmigrating mesopelagic crustaceans fishes were collected in Gulf Mexico discrete‐depth intervals (0–200 m; 200–600 600–1000 1000–1200 1200–1500 m) analyzed microplastic ingestion. We observed that 29% 26% crustacean fish individuals, respectively, ingested microplastics, with an average plastic length 0.59 ± 0.2 mm. subsample polymers was identified using Fourier Transform Infrared Spectroscopy, revealing alkyd resin (density 1.6 g cm −3 ) cellophane 1.42 mainly consumed. Our data indicate nonmigratory had significantly higher levels than migratory at all depths available comparison. While frequencies (0.28) (0.23), frequency increased depth highest m (0.40). Paired crustaceans, these observations suggest may be deeper depths. Feeding strategy also appeared correlated to ingestion, rely on gelatinous materials marine snow energy Altogether, our highlight largely undescribed temporary reservoir implicate important transport pathways size fractions open ocean.

Microplastics in Brazilian coastal environments: a systematic review

Revista Brasileira de Ciências Ambientais, Год журнала: 2024, Номер 59

Опубликована: Янв. 1, 2024

This systematic review aimed to evaluate the current scenario of research on microplastics (MPs) in Brazilian coastal environments, considering beaches and also environments not yet reported previous reviews, such as estuaries, mangroves, reefs. Five databases were consulted, 102 articles subject published between 2018 2023 selected. The universities institutions that most this period from Southeast region (37.3% articles), followed by Northeast (34.3%). Universities states Rio de Janeiro (15.7%) Pernambuco lead number publications, São Paulo (11.8%), Grande do Sul Espírito Santo (7.8%). About studied, 70% studies evaluated presence MPs beaches, 26% 2% coral Studies its marine biota corresponded 43% articles, sediment (42%), water (14%). studied organisms bony fish bivalves (17%), crustaceans (7%), seabirds turtles microfauna (5%). Despite growing, distribution study locations is still uneven related length coastline each state. As for origin, works compiled infer main sources PMs are tourism, fishing, river discharge, while action waves winds contributes dispersion these particles less urbanized remote locations.
