Large Bacterium Visible to the Naked Eye Found in Mangroves of France

In an astonishing discover, scientists have found the largest bacterium that’s 5,000 instances bigger than most recognized micro organism and is even seen to the bare eye. The organism, Thiomargarita magnifica, seems as skinny white filaments measuring roughly 1 cm in size. It was found by Olivier Gros, a marine biology professor at the Universite des Antilles in Guadeloupe, in 2009. Gros was finishing up a analysis on the marine mangrove methods when he stumbled upon the unusually huge bacterium in Guadeloupe, France. It was noticed on the surfaces of decaying mangrove leaves in the area.

Following the encounter, the bacterium was analysed in labs and microscopic research have been undertaken over the years to conclude that it was a sulphur-oxidising prokaryote.

“When I saw them, I thought, ‘Strange’. In the beginning, I thought it was just something curious, some white filaments that needed to be attached to something in the sediment like a leaf,” mentioned Gros.

Silvina Gonzalez-Rizzo, an affiliate professor of molecular biology at the Universite des Antilles and co-first creator of the new examine revealed in Science, additionally carried out the 16S rRNA gene sequencing to establish the organism.

In the new examine, a group of researchers from the JGI and Berkeley Lab, LRC, and Université des Antilles in Guadeloupe amongst others, described the large bacterium and make clear its genomic options.

Gonzalez-Rizzo mentioned that originally, she thought the organisms have been eukaryotes as they have been too huge and had quite a bit of filaments. “We realized they were unique because it looked like a single cell. The fact that they were a ‘macro’ microbe was fascinating!” Gonzalez-Rizzo added after figuring out the micro organism.

According to Jean-Marie Volland, scientists and co-author of the examine, whereas most of the micro organism have their DNA floating freely in the cytoplasm, the found bacterium had saved them organised. “The big surprise of the project was to realize that these genome copies that are spread throughout the whole cell are actually contained within a structure that has a membrane,” he added. It was learnt that the micro organism had thrice extra genes than most recognized bacterium.
