1. Biofuel
By: Jamie Demers

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.
