Nightmare bacteria

Once finished, that saving layer will help the spore become one of the best protected creatures on the planet.

Probably there is no other way of life more resistant to the extremes of the environment than a spore.

In that way a bacterium can withstand the most extreme conditions without losing the breath of life inside the spore. Thus, a microbe can survive eons (long periods). In fact, some biologists think that under these conditions a bacterium can survive more than 100 thousand years.

See how they manage to survive
Studies conducted with Echericha coli – the common intestinal bacteria – which in many ways has come to be like ‘the microbial guinea pig’, have led to a new perspective on bacteria.

Regardless of how you look at it, a colony of E. coli ‘is not made up of the same organisms’, but constitutes a highly differentiated group in which there are many types of cells: they have different sizes, shapes and enzymes.

Although a colony of bacteria begins to be created by cellular duplicates, ie individuals carrying identical DNA, differences can occur if conditions change and if other bacteria try to interact with them

Then, some bacteria will start to have mutations that allow them to adapt to the new environment or new organisms. But in that attempt to change many bacteria can die. For example, when nutrients become scarce, colonies of some species of bacteria gather to form an observable structure with the naked eye, called ‘fruit pulp’, in which 10 to 20 percent of the bacterial population is concentrated. .

When there is a problem in the environment, the bacteria of the ‘fruit pulp’ are the only ones that manage to survive. The rest of the cells may collapse and die.

There is no solid explanation for these deaths, but some say that it is possible that the dead are simply cannibalized to obtain nutrients, and that the proteins of the collapsed bacteria may be necessary to form spores and thus survive until the environmental conditions be better

Now you can understand why they do it: they do it to protect the survival of at least a small group that ensures the perpetuation of the species.

In other words, when it comes to the survival of the species, the bacteria can become spores and survive the threats of the environment.

This is how bacteria have managed to survive the attacks that humans have created against them to try to destroy them through antibiotics. In other words, this is how they have become resistant to antibiotics and have turned the heads of researchers trying to destroy them. (Vanguard Selector)
