Zitat des Tages über Bakterien / Bacteria:
I actually believe that you should not wash your jeans, ever. In Japan, they actually put them in the freezer. That kills the bacteria and makes them not smell anymore.
Think of the earth as a living organism that is being attacked by billions of bacteria whose numbers double every forty years. Either the host dies, or the virus dies, or both die.
Understanding how Cas9 is able to locate specific 20-base-pair target sequences within genomes that are millions to billions of base pairs long may enable improvements to gene targeting and genome editing efforts in bacteria and other types of cells.
You can find bacteria everywhere. They're invisible to us. I've never seen a bacterium, except under a microscope. They're so small, we don't see them, but they are everywhere.
Here at the Cold Spring Harbor Laboratory, we have genetically rearranged various viruses and bacteria as part of our medical research. In fact, we have been able to create entirely new types of DNA molecules by splicing together the genetic information from different organisms - recombinant DNA.
Biology will relate every human gene to the genes of other animals and bacteria, to this great chain of being.
Life on earth is such a good story you cannot afford to miss the beginning... Beneath our superficial differences we are all of us walking communities of bacteria. The world shimmers, a pointillist landscape made of tiny living beings.
From dead plant matter to nematodes to bacteria, never underestimate the cleverness of mushrooms to find new food!
The Safe Drinking Water Act was passed in 1974 after tests discovered carcinogens, lead and dangerous bacteria flowing from faucets in New Orleans, Pittsburgh and Boston and elsewhere.
You live in intimate association with bacteria, and you couldn't survive without them.
I think the biggest thing is clean as you go. Wash all your knives, cutting boards, dishes, when you are done cooking, not look at a sink full of dishes after you are done. Cleaning as you go helps keep away cross contamination and you avoid having food borne bacteria.
We can, for example, be fairly confident that either there will be a world without war or there won't be a world - at least, a world inhabited by creatures other than bacteria and beetles, with some scattering of others.
My bacteria glow in the dark - no human being doesn't like that.
Symbiosis can fail in various different ways: if there's too much stomach bacteria in my stomach, I might have some problems. If there's too little, I might have some problems. There's a sort of dynamic system there.
Simple genome engineering of bacteria and yeast is just the beginning of the rise of the true biohackers. This is a community of several thousand people, with skill sets ranging from self-taught software hackers to biology postdocs who are impatient with the structure of traditional institutional lab work.
I've been collecting articles on extremophile bacteria for at least the last ten years. I find them fascinating, whether they live in boiling pools at Yellowstone, around thermal vents at the floors of the oceans, or on Mars, where NASA has been searching for them as the first evidence of life beyond Earth.
Salad bars are like a restaurant's lungs. They soak up the impurities and bacteria in the environment, leaving you with much cleaner air to enjoy.
I remember the day we found the gene for the inter-species signaling molecule like it was yesterday. We got the gene, and we plugged it into a database. And we immediately saw that this gene was in an amazing number of species of bacteria. It was a huge moment of realization.
Certain foods, such as meat, appear to harbour toxic bacteria - known as endotoxins - that can trigger inflammation in your arteries, even when food is fully cooked.
Every time someone uses a bathroom and they flush, all the bacteria is shot into the air.
As far as I am concerned, LGBT can only stand for leprosy, gonorrhea, bacteria, and tuberculosis, all of which are detrimental to human existence.
Most bacteria aren't bad. We breathe and eat and ingest gobs of bacteria every single moment of our lives. Our food is covered in bacteria. And you're breathing in bacteria all the time, and you mostly don't get sick.
The usual way of growing cotton is highly petrochemical-intensive, requiring 110 pounds of nitrogen fertilizer per acre. Some of the fertilizer is broken down by soil bacteria into nitrate, a toxic and highly soluble chemical that can leach into groundwater or get washed into lakes, creating oxygenless dead zones.
We mostly don't get sick. Most often, bacteria are keeping us well.
It's incorrect to think of bacteria as these asocial, single cells. They are individual cells, but they act in communities, exactly the way people do.
Bacteria live in unbelievable mixtures of hundreds or thousands of species. Like on your teeth. There are 600 species of bacteria on your teeth every morning.
When antibiotics became industrially produced following World War II, our quality of life and our longevity improved enormously. No one thought bacteria were going to become resistant.
With the exception of autotrophic bacteria, the green, or chlorophyll-bearing, plants are the only living forms on this planet capable of synthesizing organic matter out of inorganic elements and simple compounds.
Am I simply a vehicle for numerous bacteria that inhabit my microbiome? Or are they hosting me?
Think about multicellularity on this Earth. Every living thing originally came from bacteria. So, who do you think made up the rules for how to perform collective behaviors? It had to be the bacteria.
I do definitely believe that there is life away from this planet. I mean, we've kind of established that with the fact that we found bacteria on meteorites, and we've kind of used that to backtrack and show how this Earth, this planet, could have formed the ability to sustain life in the first place.
Bacteria evolve, and so they become resistant to existing drugs. Sometimes they revert, depending on how damaging the mutation is to the life cycle of the bacteria. Mutations that give rise to resistance against particular compounds do increase, and that is why you constantly have to have new ones.
If you look at the ecological circuitry of this planet, the ways in which materials like carbon or sulfur or phosphorous or nitrogen get cycled in ways that makes them available for our biology, the organisms that do the heavy lifting are bacteria.
If a bacterium is trying to infect you, it won't secrete alone, because your immune system will block it. Bacteria will hide until they can all act together and make an impact.
