Bacteria have many superpowers

The incredible superpowers of bacteria: unveiling nature’s tiny heroes

Microbes and bacteria touch every aspect of our lives. They have so many superpowers that impact the environment, food production, bioremediation and even the climate. Here, we will look at 20 of the most fascinating bacterial superpowers and tell you where you might encounter them throughout your day. But don’t forget, there are plenty more.

Chromombacterium transports violacein within outer membrane vesicles to kill other bacteria

Bacteria firing toxic bubbles

Bacteria can form outer membrane vesicles and fill them with antibiotics. They then send these toxic bubbles off to kill competing bacteria.

Bacteria like Desulfovibrio vulgaris produce scissors that cut the bacteria free from their biofilms.

Bacteria breaking free from home

To protect themselves from the environment, bacteria build shielding biofilms houses. But once such a house gets old, bacteria need to break out it. For that, bacteria produce special scissors that can break biofilms and set free the bacteria.

Whenever a bacterium delivers a toxin into a prey bacterium, it wants to hurt it real bad. This means, that a toxin generally targets any of the essential components of the prey bacterium to make sure there is no chance of survival.

The bacterial armoury

Bacteria developed lethal killing machines to deliver toxins into other organisms. These toxic bullets have different functions to break up essential components of the prey. Independent on what the target of the toxin is, the prey surely will not come out happy after that!
