Microbial communities are groups of different microorganisms, like bacteria, fungi, viruses, phages or protozoa, that share a common place to live. These organisms can interact with each other to help or kill each other. Microbial communities are generally everywhere, as barely ever does only one species lives at a certain place.
Microbes are everywhere. And some have superpowers that allow them to grow in extremely challenging and harsh environments. Especially at the dark and cold bottom of the sea, extremophiles flourish since they interact with other microbes and eat pollutants and contaminants. Interestingly, their microbial activities can also impact our global climate.
Bacteria in your gut microbiome help you digest your food, strengthen your immune system and keep you healthy. For this, your gut bacteria keep you free from gut pathogenic bacteria by fighting them with different weapons. Here, we explore some ways gut bacteria defend pathogens and how you can help them protect you.
To feed the growing population on our planet, we need to improve our agriculture for plants to stay healthy and produce crops efficiently. One way to protect plants from diseases is to use biocontrol bacteria that actively kill intruding pathogens. Hence, by increasing our food supply, bacteria can help us save this planet.
Thiovulum majus is a large bacterium that needs a lot of nutrients and energy. To find the perfect location in shallow water, it builds white net-like veils. By attaching to these veils and fast rotation, the bacteria bring in freshwater with lots of new nutrients to keep the community alive.
Some nasty viruses can live in mosquitos and get transported into our bodies, when these infected mosquitos bite us. Luckily, some bacteria have superpowers that can fight off these viruses. Find out how the bacterium Wolbachia protects both mosquitos and us from these nasty viruses.
Pathogens and dirty particles contaminate our water supply. But helpful microbes can remove harmful bacteria and pollutants and thus clean our drinking water.
Some bacteria have special hair-like structures to connect to surfaces or other organisms. These bacterial pili help them move along that surface or pull themselves closer to a prey or host. Read about why bacteria need those pili when they are out hunting or infecting us.
Microbes produce nutrients and help promote plant growth to produce more bountiful crops and sustainable agriculture.
We live in an energy crisis in which non-renewable fossil fuels damage our planet. To switch to green biofuels as energy sources, we can rely on bacteria like Zymomonas mobilis, which produces bioethanol. Read on to find out how biofuel-producing bacterial communities can help us make this planet greener and healthier.
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.
We have created a lot of toxin pollution. Now we need microbe’s help to degrade and remove toxic materials from our environment to make our planet greener.
Bacteria are constantly attacked by other microbes like viruses. But also bacteria developed mechanisms that make them immune to viral intruders. Read on to find out how bacteria fight off viruses to protect themselves and the whole bacterial community.
Microbes are everywhere, including our favorite foods. Learn how microbes help preserve foods while also adding flavors, textures, and nutrients to our meals.
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.
Bacteria also don’t like being lonely and need to know they are not alone. And often they need to talk to other bacteria and interact with them. To do so, they use a mechanism called quorum sensing. Read on to find out more about this fascinating mechanism.
When we eat plant products, we cannot always digest all their components. Instead, our gut bacteria love plant ploymers and start degrading and digesting them. And they share the leftover food with other bacteria, so that all of them together produce some very healthy molecules for us.
Throughout your day, you’re likely using several pieces of plastics. All this plastic waste takes up space in our landfills and overflows into rivers and oceans. Luckily, some bacteria can eat and degrade plastic to help us get rid of all this clutter. Read on to learn how plastic-degrading bacteria may be the key to a greener and healthier planet.
When thinking of bacteria, you might have the picture of a single cell in your mind. But interestingly, some bacteria come as multicellular organisms with advanced functions. Here, we will learn what multicellular bacteria are and why bacteria form multicellular organisms. We will then look at some colourful examples of multicellular bacteria.
Magnetotactic bacteria have magnetosomes with which they can sense magnetic field lines. This allows magnetotactic bacteria to swim towards North or South to find the perfect location in the deep and dark water.
The bacteria and fungi living on cocoa beans degrade the sugars in the fruit. With this fermentation, the so-called cocobiota produces metabolites that give chocolate its delicious taste. Read about the microbes that are part of the cocobiota and why chocolate tastes the way it does.
