The new bacterium, named Thiomargarita namibiensis, or the "Sulfur pearl of Namibia," has cells three-quarters of a millimeter in diameter and consumes sulfide and nitrate.
Since then at least one person has remained on the international space station theguy4785 , nasa Report A woman once jumped off the 86th floor of the Empire State Building but the wind pushed her back and she fell on a … Thiomargarita namibiensis.
November 2, 2000 was the last time all humans were on the planet together. This Gram-negative Proteobacterium is found in the ocean of the continental shelf of Namibia – reflected in the bacterium’s name. The researchers named the new bacteria Thiomargarita namibiensis, which means "Sulfur Pearl of Namibia." This bacterium was first discovered in 1999 off the Namibian coast, thus was named T. namibiensis. Those electrons are eventually used to generate energy for the cell.
On average it is 0.1-0.3mm in size, but it can grow as big as a whopping 0.75mm.
The cell was photographed next to a fruit fly Drosophila viriles) of 3 mm length to give a sense of its size. Its cells are large spheres, arranged in chains, each chain enclosed in a mucous sheath. The bacteria, which Ms. Schulz named Thiomargarita namibiensis, or sulfur pearl of Namibia, reach a diameter of up to one-thirtieth of an inch or … Above there is an empty part of the sheath, where the two neighboring cells have died.
For it to function properly, your digestive system depends on these microorganisms. (e.g., cellular slime molds, myxobacteria) benefit from improved metabolic potential and perhaps better dispersal at the cost of the genomes of cells that play a supporting role (64, 65).
Source. Probiotic bacteria help your body break down nutrients, stimulate your immune system, and protect your intestines from harmful toxins and organisms. Basically, Thiomargarita namibiensis gets necessary electrons from sulfates.
Discovered in 1999 off the coast of Namibia, Thiomargarita namibiensis has the distinction of being the largest bacterium in the world, at a remarkable volume of 3 million times that of a normal bacterial specimen.

The Benefits of Probiotics. This refers to the appearance of the cells; they contain microscopic sulfur granules that scatter incident light, lending the cell a pearly lustre.
(A) The white arrow points to a single cell ofThiomargarita, 0.5 mm wide, which shines white because of internal sulfur inclusions. Non-motile Thiomargarita uses a different tactic. Lactobacillus acidophilus is a common probiotic that is available as a dietary supplement and is an ingredient in yogurts and other fermented foods. Cell Structure and Metabolism:-Thiomargarita namibiensis' environment poses the necessity for a unique adaptation: they have to be able to oxidize nitrate into sulfide in the low-nitrate conditions of their oxygen-poor habitat.This bacterium has accomplished this by having the ability to store both sulfur and nitrate. Description and Significance. It gets its enormous size because it stores huge amounts of nitrates to hold onto these electrons. Thiomargarita namibiensis!
It then uses nitrates to grab onto the electron instead of oxygen. The sulfur bacterium Thiomargarita namibiensis is a close relative of the filamentous sulfur bacteria of the genera Beggiatoa and Thioploca.It was only recently discovered off the Namibian coast in fluid sediments rich in organic matter and sulfide ().The large, spherical cells of Thiomargarita (diameter, 100 to 300 μm) are held together in a chain by mucus that surrounds each cell (Fig. Unlike other bacteria, T. namibiensis can grow so large in fact, that it is visible to the naked eye – no microscope needed! Thiomargarita means "sulfur pearl".
There are many benefits of probiotics.
