Scientists have discovered a new bacterium that is visible to the naked eye, making it the world’s largest brand.

Thiomargarita magnifica, found in the shallow mangrove swamps of the Caribbean, means that scientists are redefining what is possible for bacteria.

Unicellular organisms that do not cause disease are about 2 centimeters long and are contained within small sac bound to the membrane.

“It’s thousands of times larger than a normal-sized bacterium. Discovering this bacterium is like meeting a human as tall as Mount Everest,” said a marine biologist who published a biological study. Jean-Marie Boland says.

“This is an order of magnitude larger than what we thought was the maximum size possible for a single bacterium … they are about the same size and shape of eyelashes.”

They were discovered by Olivier Gross, a microbiologist and co-leader of research at the University of the French West, in many areas of sulfur-rich seawater in Guadeloupe, the Caribbean.

He states: “In 2009, I found long white filaments attached to the sunken leaves of a mangrove tree. Such filaments were intriguing. I went to the lab to analyze them. I put it back.

“I was very surprised to see the giant bacteria inhabiting the mangroves of Guadeloupe.”

The average bacterial species is 1-5 micrometers (equal to 0.001 mm) in length, but this species is 10,000 micrometers (4/10 inches or 1 cm) in length, doubling its length. is.

To date, the largest known bacterium was about 750 micrometers.

For a long time, Thiomargarita magnifica has not been known as the largest unicellular organism on the planet, with the aquatic alga Caulerpataxifolia occupying the top spot with a length of 15-30 cm.

Volland added that the new bacteria show that life on Earth is still awaiting discovery. “Life is fascinating, very diverse, and very complex. Curiosity and mind. It is important to keep it open. “
