Instructions and Help about Which Form 8815 Ee

Hello I'm Hank green welcome to scishow where we love slime slime is great except when it's the wrong kind of slime and when I say the wrong kind I mean the kind that can kill you biofilm also sometimes referred to as slime is a type of bacterial colony that produces a sticky organic glue which anchors the microorganisms to whatever service they fancy and also to each other making them exponentially better / worse than they would otherwise be it's also the latest addition to my list of things I wish it didn't have to worry about we didn't think of bacteria as freewheel and loners making their way through the world all by themselves and sometimes they are that way those are called planktonic bacteria but scientists are beginning to realize that bacteria actually spend most of their lives as biofilm which makes them way way way better at doing what they do whether it's helping us digest food or killing us with cholera just as living in towns and cities makes us more effective as a species bacteria living together as biofilm allows them to divvy up labour protect each other and share food and that frees up more time and resources to do the stuff like digesting in the killing their secret is the slimy goo that many bacteria secrete made up mostly of complex sugars called polysaccharides along with some proteins to form this sort of infrastructure of these bacterial towns this concoction of chemicals is actually very similar to a substance our own bodies create and that you may be familiar with mucus through this slime different bacteria can share nutrients in water they can also send signaling proteins to let them communicate they can even swap DNA to pass along their genes...
