“…Two types of PCL-degrading bacteria were isolated from deep seawater at 320 m depth in Toyama Bay. The isolated strains were identified as the Pseudomonas genus and were able to degrade PCL at 4 °C (Sekiguchi et al 2009 ). Moreover, Sekiguchi et al isolated bacteria belonging to the Shewanella , Moritella , Psychrobacter , and Pseudomonas genera from deep-sea sediment samples obtained from a depth of 5000–7000 m. Six isolated strains showed degrading abilities against a biodegradable polyester PCL.…”

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

“…For example, Pseudomonas spp. isolated from seawater in Toyama Bay (320 m depth) can degrade PCL at 4 °C [ 199 ]. Brevibacillus thermoruber isolated from Bulgarian hot spring degrades PCL at 55 °C, with a weight loss of 19.8% over four weeks [ 200 ].…”

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

“…Screening for PCL degrading bacteria from the deep-sea environments was accomplished by using a PCL-granule agar medium with a slight modification 22) . The medium of 1.0 L contained: 1.87 % MB, 1.5 % NaCl, 0.35 % KCl, 5.4 % MgCl 2 .6H 2 O, 2.7 % MgSO 4 .7H 2 O, 0.5 % CaCl 2 .2H 2 O and 1.2 % low-melting point agar (gelling temperature 30~31°C, Nacalai Tesque co., Japan).…”
