You may not know it but on our biosphere (生物圈)— Earth — there is also a relatively unknown world hiding in plain sight. It is made up of microbes (微生物) that live on floating pieces of plastic floating on the ocean.
This "Plastisphere" of microbial organism living on ocean plastic was first discovered last year and it is now getting studied. When researchers first examined the Plastisphere, they found at least 1,000 different types of microbes living on the tiny plastic islands, and worried that they might cause a risk to larger animals and humans. They also found that the Plastisphere ' s microbes included bacteria known to cause diseases in animals and humans. Since then, researchers have been trying to figure out why these potentially dangerous bacteria live on the Plastisphere, how they got there and how they are affecting the surrounding ocean.
New evidence suggests that " super-colonizers" form seeable clusters ( 叢) on the plastic in minutes. Other findings indicate that some types of harmful bacteria favor plastics more than others. And, scientists are exploring if fish or other ocean animals may be helping these pathogens ( 病原體) develop quickly by taking in the plastic. That could allow bacteria to acquire additional nutrients as they pass through the guts(腸子) of the fish, said Tracy Mincer, an associate scientist at Woods Hole Oceanographic Institution in Woods hole. Mass.
Showing this information could help scientists better understand how much of a potential threat these harmful bacteria cause and the role the Plastisphere plays in the largest ocean ecosystem, including its potential to change nutrients in the water. That information could also help reduce the impact of plastic pollution in the ocean, Mincer said.
