Two Newly-Discovered Manganese Eating BacteriasCan drinking water be detoxified more this time? That possibility was heightened at the first of two artisans' fairs to contaminate drinking water. It may be possible to filter the drinking water more accurately this time as the enemy has been identified.
These artisans are two new species of bacteria. Survivors eat the highly toxic metal manganese mixed in drinking water. Removing that toxic manganese from drinking water is still quite difficult. And after eating, they add more toxins to the drinking water. To breed them.

These two newly discovered species of bacteria have been named, ‘Candidatus manganitrophus noduliformis’ and ‘Ramlibacter lithotrophicus’.
How they were discovered?In an e-mail from Washington, Jared Ledbetter, a professor at the California Institute of Technology (Caltech), one of the leading researchers, told Enside Digital: ‘If we hadn’t thought of washing the glass jar in the lab with tap water, we might not have known about them one day!"
That shocking event ...Here is a summary of the story of Jared's discovery of two new species of bacteria.

Ledbetter was working on a pink compound in his lab. Its name is manganese carbonate. It was kept in a glass jar. Jared could not clean the jar at all. He thought he would wash the jar in water. The pink manganese carbonate will dissolve and the glass jar will be clean. With that thought, Jared filled a glass jar with tap water and went to study a short distance from the city. He returned to the laboratory after two and a half months. He was surprised to see that the glass jar had turned completely black. And there is a solid substance frozen in it. That substance is actually manganese oxide. From drinking water to groundwater, this manganese oxide is found all over the world.
Why did the glass jar turn black?"We guessed that the bacteria in the tap water had taken out the electrons from the manganese carbonate in the glass jar and made that black colored manganese oxide," Jared said. Otherwise, there is no other way to make black manganese oxide in a glass jar. Water contains manganese, it is not unknown to anyone.
Agnive Mitra, a post-doctoral researcher at Caltech, a member of the research team, said scientists had long suspected that some bacteria ate manganese to survive and thrive. More than a century ago, bacteria could remove electrons from nitrogen, sulfur, and iron. Scientists also had the idea that it was for their livelihood. But in the same way that bacteria can also remove electrons from manganese, there was no evidence in this hypothesis. Just as humans extract electrons from carbohydrates in their diet to fuel their bodies, so there is no direct evidence that bacteria also extract electrons from manganese to survive and thrive.
Of the 80 species, two were fancy"We found 60 species of bacteria in that glass jar," says Agnive. They most likely came from tap water in glass jars. In it, we find the traces of a pair of bacteria, which, when they are together, eat the manganese metal in a substance and reproduce rapidly. In doing so, it produces more toxic manganese oxide. As we have seen, those bacteria ingested manganese from the pink manganese carbonate in glass jars to form black manganese oxide. I also saw that as the number of those bacteria increases, so does the amount of manganese oxide. For which the color of the glass jar later turned completely black. From this, I realized that those bacteria are living on manganese, and their numbers are increasing rapidly. "
According to Agnive, this manganese oxide is highly toxic. Which is abundant in drinking water. For whom manganese oxide comes and mixes in the drinking water, this time it was known. As a result, the task of detoxifying drinking water seems to be easier this time.
However, Agnive also said that "it is not yet clear if the two species of bacteria live together, or whether they can do the same thing in different ways."
Whether alone or in pairs, experts do not disagree that the task of filtering drinking water has become easier this time after the enemies have been identified.
As a result, the discovery of two new species of bacteria paved the way for further filtration of drinking water.
