Pathogenic bacteria are bacteria that can cause infection.

The bacteria see the danger.

The cells that it came in contact with, it pierced them.

Some fruits get some insect damage.

111. The shifting of the location of environmental damage caused by trade may affect total global environmental damage by either increasing or decreasing it.

I collaborate with bacteria.

We genetically engineer bacteria.

And I'm going to explain exactly what damage is in concrete biological terms in a moment.

And when the molecule hits a certain amount that tells the bacteria how many neighbors there are, they recognize that molecule and all of the bacteria turn on light in synchrony.

Without water, the bacteria won't survive.

Bonnie Bassler on how bacteria talk

These bacteria live in a bottle.

let's find a way to break them down with bacteria.

Really only two things, bacteria are going to be prokaryotic and the the archaea bacteria,

I'll say bacteria as a function of time.

How does nature repel bacteria?

It's a race between you and the bacteria.

Well, that is the bacillus which causes leprosy!

Symbiotic bacteria on the exterior surface of the ants produce antibiotics that kill bacteria introduced into the nest that may harm the fungi.

As with bacterial classification, identification of bacteria is increasingly using molecular methods.

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

They wished they knew how to prevent their food supply from sometimes failing, and how they could rest when they were tired without risking starvation, be warmer, cooler, safer, in less pain.

And you'll see, there's some damage to the surface of the coral.

But it turns out, you don't need something six miles across to do a lot of damage.

In general, viruses are much smaller than bacteria.

Bacteriology is the study of bacteria.

And this is where my collaboration with bacteria comes into play.

It goes on in nature today, and the bacteria die as soon as we stop feeding them.

Hey, these are bacteria.

We heard that bacteria eat oil?

JY

It's probably a good source of bacteria.

They also kill bacteria essential to the proper balance of the aquatic environment, endangering the survival of species dependent on those bacteria.

One of the interesting things about these particular guys is that they're in the actinomycete and streptomycete groups of the bacteria, which is where we get most of our antibiotics.

And when the molecule hits a certain amount that tells the bacteria how many neighbors there are, they recognize that molecule and all of the bacteria turn on light in synchrony.

It's also, by the way, a characteristic of certain kinds of brain damage.

Wonderful the damage one of these little machines can do you'd never believe it.

So we went back to molecular biology and started studying different bacteria, and what we've found now is that in fact, bacteria are multilingual.

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

Bacteria as a function of time is going to be equal to the initial bacteria, or the initial of whatever we have for doing compound interest is the amount we start with, e to the kt.

And these metals accumulate as minerals on the surface of the bacteria.

These vibrios, these bacteria, can actually infect people.

The shell protects the eggs from predators, bacteria, damage, and drying out.

Our gut is a wonderfully hospitable environment for those bacteria.

We use bacteria to clean our water.
