Bacteria produce antibiotics to fight off microbial competitors. Antibiotics are chemical molecules that inhibit a certain cellular machine to kill the competitor.
Here you will learn which antibiotics bacteria produce and how they help the bacteria survive.
Antibiotics are often described as ‘magic bullets’, but bacteria will surely disagree. To them, antibiotics are molecules that try to kill them by disrupting essential cellular processes. In this post, we’ll discuss how antibiotics work and why bacteria experience so-called stress upon an antibiotic attack.
Our world as well as the bacterial world are full of vibrant colours. These colours exist thanks to biopigments; molecules able to capture light and reflect the corresponding colour. Many organisms, as well as bacteria, learned to use biopigments to harvest energy from sunlight, fight foes and adapt to new and challenging environments. Read on to learn what makes the bacterial world so colourful and why biopigments are the Earth’s life savers.
We use antibiotics to kill bacteria and fungi. Yet, antibiotics are produced by these microbes to ensure their own survival in the environment. But not only microbes that produce antibiotics benefit from them, but often even other organisms. Read on to find out how antibiotics can help many players.
Bacteria divide by measuring their middle and forming a ring. They then extend their cells while the ring tightens. Like this, two daughter cells grow out of one mother cell. However, the daughter cells do not always look the same…
A deadly fungus kills many exotic amphibians. Luckily, some bacteria antibiotics to kill the fungal intruder and thus protect the animal. With this colourful strategy, the right microbial community might even save whole species from extinction.
In bacterial battles, there is more than just direct killing. Some bacteria even fight by destroying the houses of their opponents. We could learn a lot from these bacterial wars for our own fights against bacterial superbugs.
For a bacterium to understand what is going on in the environment, it needs some sophisticated mechanisms. One of these includes destroying proteins. Here, we will look at why bacteria destroy proteins and how it helps them to survive.
The players in the microbial world always interact with each other driving ecology and evolution forward. Bacteriophages thank their bacterial hosts for their production in a very special way: They protect bacteria from antibiotic attacks by forming shielding walls around the cells. While the microbial world gets more and more complex with such mechanisms, it also represents another strategy for antimicrobial resistances.
Bacteria can form outer membrane vesicles and fill them with antibiotics. They then send these toxic bubbles off to kill competing bacteria.
Your gut microbiome is full of helpful and fascinating bacteria. They all work together to keep you healthy, digest your food and fight off intruders. Here, you will learn about what a healthy gut microbiome is, what it does and how to keep it.
Bacteria use one-component systems and two-component systems to sense their environment and adapt to changing conditions.
Bacteria can be major problems for human health. One of the reasons for that is because they have the ability to hide in their own houses. Such a house is called a bacterial biofilm which protect bacteria from harsh environments, toxic chemicals and to form a community within the biofilm.
Bacteria developed different antimicrobial resistance mechanisms to get rid of antibiotics. Here, you will learn what bacteria do with antibiotics so that they don’t harm them and what superbugs are.
