Maximum bacteria like eyelashes

Bacteria are usually small, and they can be seen with the help of microscope. However, a bacteria found in the Caribbean area are visible to the naked eye, and the shape and length are similar to human eyelashes. It is currently known as the largest bacteria.

"Mount Everest" in bacteria

According to the papers published by Science Magazine on the 23rd, this bacteria is called "Gorgeous Sulfuria" and found in the Gwadelu Islands in the Leez Islands of Xiaoan, Caribbean. The average length of this bacterial cells exceeds 9,000 microns, which is almost 1 cm. Most of the bacteria length is only 2 microns, even if it is only 750 microns.

One of the authors of the research report, the United States Department of Energy's Joint Genome Research Institute Marine Biologist Jean Mali Wallan, said that gorgeous sulfurium can grow to the maximum of 2 cm. For example, he said that this bacterial bacteria are thousands of times larger than the "normal body type", "discovering this bacteria like a person who is as tall as Mount Everest."

According to the United States Cable Television News Network, due to the huge body, only a gorgeous sulfurium surface can accommodate more than 625,000 E. coli. However, researchers have found that the surface status of gorgeous sulfur pearls is "especially primitive", and there are no bacteria that usually live on the surface of the plant or animal surface.

Unique cell structure

Scientists have previously believed that bacteria cannot grow up to the point where the naked eye can be visible. Gorgeous sulfur can grow into a "big head" in bacteria, which may be related to its unique cell structure.

Most of the bacteria are single -cell creatures, and genetic materials flow freely in cells. The cells of gorgeous sulfur pearls have a membrane sac, loading genetic materials like pockets. According to Voli, this situation is very rare in bacteria. He said that this more complicated structure is more common in cells such as humans, animals and plants. Researchers hope to learn more about this membrane and study whether they affect the shape of gorgeous sulfur.

The research report another author Olivier Gross saw a white silk on the leaves sinking into the water in the mangroves of Guadelop Island in 2009. He brought them back to the laboratory and found gorgeous. Sulfuria.

This huge bacteria can also grow in the mud containing sulfur, which can also grow. The chemical energy of the sulfur is used to generate sugar in the water, and it can also use carbon dioxide to synthesize energy. Volland said that the discovery of gorgeous sulfur and pearlite shows that Earth creatures still have more surprises waiting for discovery. (Yuan Yuan)
