BiofuelBy: Jamie Demers

Intro Biofuels used to be taking farming and

using the crops as fuel

Now, bacteria is used

How it works Bacteria with recombinant DNA

The bacteria uses common foods

And makes ethanol or diesel as a waste

Different uses Some bacteria make electricity

Some make ethanol

Some make diesel

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.

Ethanol The materials and methods are the

same or similar to making biodiesel

The only difference is that the gene is different

Electricity Microbial fuel cells convert glucose to

electricity

The bacterial colonies create an electrode surface up to 3.6 W m

How it works Scientists first 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

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.

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

Impact This could 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.
