Degradation of plastics and plastic-degrading bacteria in cold marine habitats

Applied Microbiology and Biotechnology, Journal Year: 2018, Volume and Issue: 102(18), P. 7669 - 7678

Published: July 11, 2018

Synthetic plastics present in everyday materials constitute the main anthropogenic debris entering Earth's oceans. The oceans provide important and valuable resources such as food, energy, water. They are also way of international trade stabilizer climate. Hence, changes marine ecosystem caused by influences plastic pollution can have a dramatic impact on global scale. Although problem still remains unsolved, different ways being considered to reduce their environment. One them is use microorganisms capable degradation plastic. A particularly interesting area application isolated from cold regions view unique characteristics. Nevertheless, interactions between poorly known. Here, we review current knowledge plastic-microorganism habitats. Moreover, highlight advantages this environment for eliminating waste ecosystems.

Marine microplastics as vectors of major ocean pollutants and its hazards to the marine ecosystem and humans

Progress in Earth and Planetary Science, Journal Year: 2021, Volume and Issue: 8(1)

Abstract Microplastic pollutes water, land, air, and groundwater environments not only visually but also ecologically for plants, animals, humans. has been reported to act as vectors by sorbing pollutants contributing the bioaccumulation of pollutants, particularly in marine ecosystems, organisms, subsequently food webs. The inevitable exposure microplastic humans emphasises need review potential effects, pathways, toxicity toward human health. Therefore, this was aimed reveal risks pollutant sorption humans, well dominant types sorbed microplastic, that are bioaccumulated living organisms ecosystem. possible factors influencing ecosystems were reviewed. revealed prevailing abundance geographical distribution aquatic environment globally. literature characteristics, chemical interactions, water properties played a role microplastic. evidence posing direct medical threat is still lacking albeit substantial health hazards microplastic-associated monomers, additives, pollutants.

Microbial Ecotoxicology of Marine Plastic Debris: A Review on Colonization and Biodegradation by the “Plastisphere”

Frontiers in Microbiology, Journal Year: 2019, Volume and Issue: 10

Published: April 25, 2019

Over the last decades, it has become clear that plastic pollution presents a global societal and environmental challenge given its increasing presence in oceans. A growing literature focused on microbial life surfaces of these polluants, called 'plastisphere', but general concepts ecotoxicology have only rarely been integrated. Microbial deals with (i) impact pollutants communities inversely (ii) how much microbes can influence their biodegradation. The goal this review is to enlighten 15 years related First, we focus marine various functions ensures ecosystems. In part, also discuss driving factors influencing biofilm development potential role debris as vector for dispersal harmful pathogen species. Second, give critical view extent which microorganisms participate decomposition oceans relevance current standard tests biodegradability at sea. We highlight some examples metabolic pathways polymer conclude several questions regarding gaps knowledge biodegration by identification possible directions future research.

Marine Plastic Debris: A New Surface for Microbial Colonization

Environmental Science & Technology, Journal Year: 2020, Volume and Issue: 54(19), P. 11657 - 11672

Published: Sept. 4, 2020

Plastics become rapidly colonized by microbes when released into marine environments. This microbial community—the Plastisphere—has recently sparked a multitude of scientific inquiries and generated breadth knowledge, which we bring together in this review. Besides providing better understanding community composition biofilm development ecosystems, critically discuss current research on plastic biodegradation the identification potentially pathogenic "hitchhikers" Plastisphere. The Plastisphere is at interface between its surrounding milieu, thus drives every interaction that synthetic material has with environment, from ecotoxicity new links food webs to fate plastics water column. We conclude so far not shown communities starkly differ other inert surfaces, particularly true for mature assemblages. Furthermore, despite progress been made field, recognize it time take plastic–Plastisphere–environment interactions step further identifying present gaps our knowledge offering perspective key aspects be addressed future studies: (I) physical characterization biofilms, (II) inclusion relevant controls, (III) study different successional stages, (IV) use environmentally concentrations biofouled microplastics, (V) prioritization gaining mechanistic functional communities.

Marine Microbial Assemblages on Microplastics: Diversity, Adaptation, and Role in Degradation

Annual Review of Marine Science, Journal Year: 2019, Volume and Issue: 12(1), P. 209 - 232

Published: June 21, 2019

We have known for more than 45 years that microplastics in the ocean are carriers of microbially dominated assemblages. However, only recently has role microbial interactions with marine ecosystems been investigated detail. Research this field focused on three main areas: (a) establishment plastic-specific biofilms (the so-called plastisphere); (b) enrichment pathogenic bacteria, particularly members genus Vibrio, coupled to a vector function microplastics; and (c) degradation environment. Nevertheless, relationships between microorganisms remain unclear. In review, we deduce from current literature, new comparative analyses, considerations adaptation concerning plastic microplastic particles should rather limited effects ecosystems. The majority growing seem belong opportunistic colonists do not distinguish natural artificial surfaces. Thus, pose higher risk life forms by potentially harboring bacteria. On other hand, represent recalcitrant substances insufficient support prokaryotic metabolism will probably be degraded any period time relevant human society. Because cannot remove ocean, proactive action regarding research alternatives strategies prevent entering environment taken promptly.

Microplastics provide new microbial niches in aquatic environments

Applied Microbiology and Biotechnology, Journal Year: 2020, Volume and Issue: 104(15), P. 6501 - 6511

Published: June 4, 2020

Abstract Microplastics in the biosphere are currently of great environmental concern because their potential toxicity for aquatic biota and human health association with pathogenic microbiota. can occur high abundance all environments, including oceans, rivers lakes. Recent findings have highlighted role microplastics as important vectors microorganisms, which form fully developed biofilms on this artificial substrate. therefore provide new microbial niches environment, developing may significantly differ composition compared to natural free-living or particle-associated populations surrounding water. In article, we discuss ecological function communities found microplastic biofilms. The factors that influence richness diversity such also evaluated. Microbe-microbe microbe-substrate interactions been little studied not well understood. Multiomics tools together morphological, physiological biochemical analyses should be combined a more comprehensive overview These so far unknown consequences ecology processes ecosystems. More knowledge is required community functions order better evaluate environment animal health, humans, especially since worldwide predicted dramatically increase. Key Points • Bacteria mainly analyses: fungi neglected. Microbial colonization depends substrate, location time. Community promising approach investigate colonization. Biodegradable plastics, roles biofilms, need analysis.
