We couldn't turn off the nitric oxide.

Well, that's just mercury and nitric acid.

Bacteria.

Pasteur experimented with bacteria.

I collaborate with bacteria.

Hey, these are bacteria.

We genetically engineer bacteria.

We throw in bacteria.

Hey look, this bacteria should, you know, I am some bacteria said

The esca holds bioluminescent bacteria.

The bacteria see the danger.

How does nature repel bacteria?

And they were the first people to describe this new chemical transmitter, nitric oxide.

So this represent this would be just a few little bacteria here, many, many bacteria...

Bacteria will not breed in alcohol.

Bacteria are just tiny cells, harmless.

Viruses are much smaller than bacteria.

You say bacteria, those are germs.

They attack bacteria, they kill them.

We heard that bacteria eat oil?

In a petri dish, bacteria grow.

These bacteria live in a bottle.

This is a bacteria right here.

Roughly 1 100 of a bacteria.

But since bacteria have hard walls, they will just inject the DNA inside of the bacteria.

What nitric oxide does is it dilates blood vessels, so it lowers your blood pressure.

So now that we found bacteria that could break down phthalates, we wondered what these bacteria were.

The first time I ever heard of a lung specialist experimenting with cellulose and nitric acid.

And I started doing research, and we found, very excitingly, that the skin produces nitric oxide.

It seemed we couldn't turn off the production of nitric oxide in the skin of humans.

Bacteria are invisible to the naked eye.

The smallest bacteria is about 200 nanometers.

It's a small virus that kills bacteria.

We use bacteria to clean our water.

And it's killing bacteria. It's eating them.

Bacteria always control pathogenicity with quorum sensing.

Like produce washes, running water doesn't kill bacteria but it can be effective in helping wash bacteria away.

Some bacteria figured out how to stay away from penicillin, and it went around sort of creating its little DNA information with other bacteria, and now we have a lot of bacteria that are resistant to penicillin, because bacteria communicate.

What was actually interesting to us was not that the bacteria made light, but when the bacteria made light.

And the reason for this, it turned out, after two or three years' work, was that in the skin we have huge stores not of nitric oxide, because nitric oxide is a gas, and it's released (Poof!) and in a few seconds it's away, but it can be turned into these forms of nitric oxide nitrate, NO3 nitrite, NO2 nitrosothiols.

These vibrios, these bacteria, can actually infect people.

Mud and minerals become substrate there are bacteria.

So, the bacteria grows hair on the crab.

Bacteria are incredibly multi drug resistant right now, and that's because all of the antibiotics that we use kill bacteria.

Because viruses that attack bacteria might sometimes the bacteria is far worse for the virus but these are called bacteriaphages.
