Where is the Plastisphere?

The Plastisphere is defined as the thin layer of life found on the outer surface of PMD. Plastisphere microbial communities on microplastics (<5 mm) collected from open ocean surface waters are distinct from the surrounding seawater and harbor a diversity of microbial species including potential pathogens.

Who coined the term Plastisphere?

The plastisphere was first described by a team of three scientists, Dr. Linda Amaral-Zettler from the Marine Biological Laboratory, Dr. Tracy Mincer from Woods Hole Oceanographic Institution and Dr. Erik Zettler from Sea Education Association.

What makes the Plastisphere an ecosystem?

In the plastisphere there are organisms that photosynthesise; there are predators and prey; symbionts and parasites, allowing for “a full gamut of interactions possible, as in other ecosystems”, says Amaral-Zettler.

Why do scientists worry about the Plastisphere as a way of spreading disease in the marine environment?

The plastisphere is a home for bacteria Microplastics (small plastic pieces) in the ocean are perfect for bacterial cells to grow. Scientists found that the plastisphere, the region surrounding microplastics, can serve as a ‘home’ for cells that cause disease, called pathogens.

What is the name of the Garbage Patch between Hawaii and California?

The Great Pacific Garbage Patch
The Great Pacific Garbage Patch, also known as the Pacific trash vortex, spans waters from the West Coast of North America to Japan. The patch is actually comprised of the Western Garbage Patch, located near Japan, and the Eastern Garbage Patch, located between the U.S. states of Hawaii and California.

How does the plastic in the barnacles affect the ecosystem?

“Barnacles may be at the lower levels of the food chain, but what they consume will be transferred to the organisms that eat them. In addition, plastics are capable of absorbing pollutants and chemicals from the water.

What is Mineralisation plastic?

– Mineralization is the ultimate step in the biodegradation of a plastic polymer and results in the excretion of completely oxidized metabolites (CO2, N2, CH4, and H2O).

Are there bacteria that eat metal?

Leptospirillum ferriphilum can “eat” a nail in three days flat. New metal-eating bacteria could help break down and reduce mining waste. The bacteria eat metal objects and discharge a metal-leaching fluid called a lixiviant. Through this process, bacteria can “eat” a metal nail in just three days.

What is the purpose of barnacles?

Because they are filtering organisms, they play an important role in the food chain. Barnacles are suspension feeders, consuming plankton and dissolved detritus suspended in seawater and are therefore essential in cleansing that water for other organisms.

Are there bacteria that eat gold?

An international team of researchers has figured out how one metal-gobbling bacterium, Cupriavidus metallidurans, manages to ingest toxic metallic compounds and still thrive, producing tiny gold nuggets as a side-effect.
