Plastic degradation in marine bacteria describes when certain pelagic bacteria break down polymers and use them as a primary source of carbon for energy. Polymers such as polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET) are incredibly useful for their durability and relatively low cost of production, however it is their persistence and difficulty to be properly ...
Specifically, the study examined the edible tissue of fish often fished along the Oregon coast or sold in the state's markets: black rockfish, lingcod, Chinook salmon, Pacific herring, Pacific ...
These microplastics are frequently consumed by marine organisms at the base of the food chain, like plankton and fish larvae, which leads to a concentration of ingested plastic up the food chain. Plastics are produced with toxic chemicals, so these toxic substances enter the marine food chain, including the fish that some humans eat. [39]
A study in 2023 tested some fish species and found that “about 80% of the MPs detected were fibrous in shape and were made of polyethylene (25%), polyester (20%), and polyamide (10%). Most microplastic particles observed were black (61%) or blue (27%) in color.” [ 162 ]
Some of these toxic chemicals are discharged into lakes, rivers, the ocean, and groundwater. Animals, plants, and water surfaces can also be exposed from airborne chemical emissions caused from cities, factories, and fires (Fantke, 2020). Chemical sludge often gets into agricultural and industrial soils as well. [citation needed]
In 1996, Monsanto discovered a method of producing one of the two polymers in plants and acquired Biopol from Zeneca, a spinout of ICI, as a result of the potential for cheaper production. [ 11 ] As a result of the steep increase in oil prices in the early 2000s (to nearly $140/barrel US$ in 2008), the plastic-production industry finally sought ...
iStockWhether it's salmon, cod, mackerel, or tuna, eating more fish has many health benefits. For example, a 2021 meta-review found that increased fish consumption is linked to improved ...
Once formed, these two compounds can be further biodegraded into carbon dioxide by I. sakaiensis or other microbes, or purified and used to manufacture new PET in an industrial recycling plant setting. [1] [7] Ideonella sakaiensis is being studied for its PET-degrading capabilities in sewage-fed fisheries. Various strains of this bacterium have ...
