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

Applied Microbiology and Biotechnology, Год журнала: 2018, Номер 102(18), С. 7669 - 7678

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.

Environmental Factors Support the Formation of Specific Bacterial Assemblages on Microplastics

Frontiers in Microbiology, Год журнала: 2018, Номер 8

While the global distribution of microplastics (MP) in marine environment is currently being critically evaluated, potential role MP as a vector for distinct microbial assemblages or even pathogenic bacteria hardly understood. To gain deeper understanding, we investigated how different situ conditions contribute to composition and specificity MP-associated bacterial communities relation on natural particles. Polystyrene (PS), polyethylene (PE), wooden pellets were incubated 2 weeks along an environmental gradient, ranging from (coastal Baltic Sea) freshwater (waste water treatment plant, WWTP) conditions. The associated well applying high-throughput 16S rRNA gene sequencing. Our setup allowed first time determine MP-dependent -independent assemblage factors subject one system. Most importantly, plastic-specific found develop solely under certain conditions, such lower nutrient concentration higher salinity, while genus Erythrobacter, known ability utilize polycyclic aromatic hydrocarbons (PAH), was specifically across broader section gradient. We discovered no enrichment pathogens PE PS; however, abundant colonization WWTP by commonly with antibiotic resistance suggests possible hotspot horizontal transfer. Taken together, our study clarifies that surrounding prevailingly shapes biofilm communities, but MP-specific exist. These findings point ecological significance specific MP-promoted populations aquatic environments particularly plastic accumulation zones.

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

Frontiers in Microbiology, Год журнала: 2019, Номер 10

Опубликована: Апрель 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.

Plastics in the marine environment are reservoirs for antibiotic and metal resistance genes

Environment International, Год журнала: 2018, Номер 123, С. 79 - 86

Опубликована: Ноя. 28, 2018

Plastics have been accumulated offshore and in the deep oceans at an unprecedented scale. Microbial communities colonized plastisphere, which has become a reservoir for both antibiotic metal resistance genes (ARGs MRGs). This is first analysis of diversity, abundance, co-occurrence ARGs MRGs, their relationships within microbial community, using metagenomic data plastic particles observed North Pacific Gyre obtained from National Centre Biotechnology Information Sequence Read Archive database. The abundance MRGs on plastics were ranges 7.07 × 10 −4 –1.21 −2 5.51 −3 –4.82 copies per 16S rRNA, respectively. Both Shannon-Wiener indices richness microbiota significantly greater than those seawater via one-way variance. Multidrug multi-metal main classes detected microbiota. There no significant differences or diversity between macroplastics biota microplastics biota, indicating that particle size had effect genes. Procrustes suggested community composition was determining factor ARG profile but not MRG. Some higher incidence non-random co-occurrence, suggesting co-effects selection are important factors influencing resistome particles. • Plastic does influence Metal abundances Bacterial driving MRG Flavobacteriaceae family bacteria potential host MRGs.

Marine Plastic Debris: A New Surface for Microbial Colonization

Environmental Science & Technology, Год журнала: 2020, Номер 54(19), С. 11657 - 11672

Опубликована: Сен. 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, Год журнала: 2019, Номер 12(1), С. 209 - 232

Опубликована: Июнь 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.
