2. Intro
Biofuels
used to be taking farming and
using the crops as fuel
Now, bacteria is used
3. How it works
Bacteria with recombinant DNA
The bacteria uses common foods
And makes ethanol or diesel as a waste
4. Different uses
Some bacteria make electricity
Some make ethanol
Some make diesel
5. Diesel
Using sugar, and even better, cellulose
Most recently, E. Coli is used
They also used E. Coli to create an
enzyme that breaks down plants into the
cellulose they need.
6. Ethanol
The materials and methods are the same
or similar to making biodiesel
The only difference is that the gene is
different
7. Electricity
Microbial fuel cells convert glucose to
electricity
Thebacterial colonies create an
electrode surface up to 3.6 W m
8. How it works
Scientistsfirst take genes from various
plants or bacteria
There are three genes they take
One to break down cellulose
One to tell the bacteria to secrete the
enzyme
And one to convert the sugar to biodiesel
9. What about electricity?
The gene is taken from various bacteria
Only one gene sequence is used for this
It uses glucose to drain off their electrons.
10. Ethical concerns
Fortunately for biofuel producers
There are relatively no ethical issues with
biofuels
Only one
Some people don’t like scientists messing
with genetic code
11. Impact
Thiscould have a huge impact on the
world
We would no longer need to use fossil
fuels
And the fear of running out of oil will be
gone.
