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 ...
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]

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 ...

Aquatic toxicology is the study of the effects of manufactured chemicals and other anthropogenic and natural materials and activities on aquatic organisms at various levels of organization, from subcellular through individual organisms to communities and ecosystems.

They produced and patented one of the first polyester fibers which they named Terylene, also known as Dacron, equal to or surpassing nylon in toughness and resilience. [8] ICI and DuPont went on to produce their own versions of the fiber. The world production of synthetic fibers was 55.2 million tonnes in 2014. [9]
The larvae hatch and eat the sloth poop. When they are adults, they fly up to the sloths living in the trees and colonize their hair. The moths are weak fliers and once they land on a sloth, they ...
Textile fibres or textile fibers (see spelling differences) can be created from many natural sources (animal hair or fur, cocoons as with silk worm cocoons), as well as semisynthetic methods that use naturally occurring polymers, and synthetic methods that use polymer-based materials, and even minerals such as metals to make foils and wires.
