A cup of clean water contains ... 10 million bacteria

The clean water everyone is using to eat and drink every day may not be as clean as we thought. According to a new study, tap water used in our daily activities contains up to 10 million bacteria.

However, you should not be too worried, because all the "terrible" bacteria in fact can improve our water quality.

Researchers from the University of Lunch (Sweden) discovered that these micro-microbes grow at the water treatment plant and face in the water pipes. Although harmless but over time, they can form a thin, sticky membrane inside the pipes, called "biofilms" (biofilm).

The new discovery also reveals a great variety of bacteria that reside in water pipes and that they play a more important role than long-term conjecture.

"A previously unknown ecosystem has exposed itself to us. Previously, it was difficult for us to see any bacteria, but now, thanks to techniques, such as Solving large-scale DNA sequences and analyzing cell flow, we suddenly observed 80,000 bacteria in each ml of drinking water.

All like being in the dark with a flashlight, we are now in a room lit with lights. But this is just a room. How many rooms in the house is an interesting question , ' explains researcher Catherine Paul.

According to experts, there are at least 2 thousand different species of bacteria in water biology t. They also discovered a link between the composition of bacteria and water quality.

The team suspects that "good" bacteria help purify water and keep water safe, similar to what happens inside our bodies. For example, our intestines are full of bacteria and most of the time when we are healthy, they help us digest food and fight disease.

Researcher Catherine Paul took the example of Sphingomonas - bacteria found only in high quality drinking water . This bacterium can absorb unwanted organic materials, chlorine tolerance and even eliminate other toxins and plastic forms that can block them in water.

Other types of bacteria also imply that something is not good in the water, which leads to a pipeline rust or reduced chlorine concentration.

The researchers now hope, we can finally control the composition and quality of water in the water supply, to promote the development of potential "good" bacteria to help. Water purification is even more effective today.
