Detailed explanation-1: -When plastics end up in the environment, they can bind with these pollutants, including persistent organic toxins such as PCBs (Polychlorinated biphenyls) and dioxins, both of which are not only very resistant to degradation but can also accumulate in animal fats and tissues.
Detailed explanation-2: -Ideonella sakaiensis is a bacterium from the genus Ideonella and family Comamonadaceae capable of breaking down and consuming the plastic polyethylene terephthalate (PET) using it as both a carbon and energy source.
Detailed explanation-3: -It works by secreting an enzyme (a type of protein that can speed up chemical reactions) known as PETase. This splits certain chemical bonds (esters) in PET, leaving smaller molecules that the bacteria can absorb, using the carbon in them as a food source.
Detailed explanation-4: -Among bacteria involved in bioremediation processes, most belong to the genera Alcaligens, Achromobacter, Acinetobacter, Alteromonas, Arthrobacter, Burkholderia, Bacillus, Enterobacter, Flavobacterium, Pseudomonas [22, 23].
