Transcript of Green Bacteria

What First comes to Mind when you Hear "Bacteria?"
Green Bacteria
While some bacteria can be considered bad or harmful, there many examples of how bacteria is helpful to us and the environment

WRONG!!

Bioremediation
is the natural process of using microbes to break down pollutants.
It served as a way for prehistoric prokaryotes to obtain energy from simple compounds.
Scientists have used genetically modified bacteria to break down pollutants in water and soil.
.
Bioremediation
Some bacteria
break down
dead organisms

and waste to obtain nutrients
Bacteria that lives on dead organic matter is called
saphrotrophic
bacteria
Saphotrophic bacteria's grows in the soil
As dead matter reaches the soil, the bacteria "eat" it and produce compost, which allows soil to retain nutrients, air, and water for plants
Decomposition
Some bacteria digest toxic waste and
generate electricity
at the same time
They use appendages called
nanowires
that can be pricked with platinum electrodes to carry a current
They could one day be used in waste and water treatment plants to simultaneously digest waste and power the facilities.
Electricity
A bacteria that lives in soil, called
Geobacter bacteria
, uses its nanowires to make
uranium
insoluble in a process called
electroplating
That way it can't dissolve into groundwater
Radioactivity
There are many more!!

How it Works
Alcanivorax bacteria take oxygen and nutrients out of seawater as fuel for breaking down oil.
Waste is broken down and CO2 and water are emitted.
The rate of bioremediation must be monitored to control the amount of damage done by depletion of oxygen in seawater and the addition of carbon in the atmopsphere.
Carbon produced by bioremediation contributes to global warming, while taking nutrients and oxygen from the ocean kills marine life, creating dead zones.

Pseudomonas
Break down plastic bags
T-103
Makes the biofuel, butanol, out of paper
Clostridium sporogenes
Delivers drugs in cancer therapy
Microbes in panda feces
Make Biofuel from broken down plant matter ,called lignocellulose
Brocadia anammoxidans
Makes hydrazine, or rocket fuel
