ClearMicroplastics under siege: Biofilm-forming marine bacteria from the microplastisphere and their role in plastic degradation
Researchers isolated and screened bacteria from microplastics collected along coastal beaches of the Andaman and Nicobar Islands to assess their ability to degrade plastic. One bacterial strain achieved over 10% degradation of low-density polyethylene, with surface analysis confirming physical breakdown of the plastic. The study suggests that naturally occurring marine bacteria colonizing microplastics may play a role in plastic biodegradation in ocean environments.
Marine bacteria capable of enzymatic degrading of low- and high-density polyethylene: Toward sustainable mitigation of marine microplastic pollution
Scientists discovered ocean bacteria that can break down common plastic types found in marine pollution, with some bacteria destroying up to 17% of the plastic in lab tests. These naturally occurring bacteria could potentially be used to help clean up the tiny plastic particles that contaminate our oceans and eventually enter our food chain through seafood. While still in early research stages, this finding offers hope for a biological solution to reduce the microplastics that may pose health risks when we consume contaminated fish and shellfish.

Bacterial screening in Indian coastal regions for efficient polypropylene microplastics biodegradation
Researchers screened marine bacteria from two coastal regions in India for their ability to break down polypropylene microplastics. They identified several bacterial strains that caused measurable weight loss and structural changes in polypropylene particles over a 60-day period. The study suggests that naturally occurring marine bacteria could potentially be harnessed for biological approaches to reducing microplastic pollution in ocean environments.
Biodegradation of untreated plasticizers-free linear low-density polyethylene films by marine bacteria
Researchers isolated marine bacteria from the Tyrrhenian Sea and found that several strains — including Bacillus velezensis and two Vreelandella species — could break down untreated polyethylene plastic films in seawater, causing mass losses of up to 2.6% over 60 days. This is the first study demonstrating that these bacterial species can biodegrade plasticizer-free, unmodified polyethylene, an important step toward understanding natural plastic degradation in oceans.
The Role Of Bacteria In Microplastic Bioremediation And Implications For Marine Ecosystems
This literature review summarizes how bacteria can be harnessed through bioremediation to break down microplastics in marine environments, cataloging the bacterial species and mechanisms involved. While biological degradation is slow and not yet a practical cleanup solution at scale, identifying effective bacteria is an important step toward developing tools to reduce the long-term accumulation of microplastics in ocean ecosystems.
Biodegradation assessment of polymer-based films by bacterial species in the marine environment and its correlation with microplastic production and toxicity
Researchers tested five polymer-based film materials in marine environments and measured biodegradation, bacterial colonization, and microplastic formation, finding that polymer composition strongly determines both marine biodegradability and the amount of microplastic debris generated during degradation.
Isolation and Characterization of Polyethylene and Polyethylene Terephthalate-degrading Bacteria from Jakarta Bay, Indonesia
Researchers isolated bacteria from Jakarta Bay, Indonesia, that showed the ability to degrade polyethylene and polyethylene terephthalate microplastics in laboratory conditions. They identified the most effective bacterial strains and confirmed plastic degradation through weight loss measurements and surface analysis. The study supports the potential of using naturally occurring marine bacteria for bioremediation of plastic-polluted coastal environments.
Putative degraders of low‐density polyethylene‐derived compounds are ubiquitous members of plastic‐associated bacterial communities in the marine environment
This study compared bacterial communities on plastic debris from the Pacific, North Atlantic, and northern Adriatic to identify potential plastic-degrading microbes, finding that putative LDPE-degraders are widespread and common members of ocean plastic biofilms. The widespread distribution of plastic-degrading bacteria in ocean environments suggests that biological plastic breakdown is occurring in the ocean, but at an unknown rate.
Biofilm development as a factor driving the degradation of plasticised marine microplastics
Researchers investigated how natural marine biofilms drive the degradation of plasticized microplastics. The study found that biodegradation was dependent on polymer type, plasticizer type, and time, with polystyrene containing bisphenol A showing the most degradation, coinciding with increased abundance of putative biodegradative bacteria in the colonizing biofilm.
Bacterial Abundance, Diversity and Activity During Long-Term Colonization of Non-biodegradable and Biodegradable Plastics in Seawater
Biofilm communities on conventional (polyethylene and polystyrene) and biodegradable plastics were tracked over 7 months of seawater immersion, finding highly abundant and diverse plastisphere communities on all polymer types but limited evidence of active plastic biodegradation under natural marine conditions.

Biodegradable plastics in Mediterranean coastal environments feature contrasting microbial succession
Researchers incubated biodegradable and conventional plastics in three Mediterranean coastal environments for 22 months and found that the surrounding habitat — not the plastic type — primarily shaped which microbes colonized the surface. Despite some putative plastic-degrading bacteria being present, there was no consistent community of microbes clearly linked to biodegradable plastic breakdown in natural marine settings.
Degradation of subµ-sized bioplastics by clinically important bacteria under sediment and seawater conditions: Impact on the bacteria responses.
Researchers found that clinically important bacteria colonized submicron-sized bioplastic particles in both seawater and sediment and showed biochemical stress responses to the bioplastics. The ability of pathogens to form biofilms on bioplastic surfaces in marine environments raises concerns that bioplastics, like conventional plastics, could act as vectors for disease-causing microorganisms.
