Ethanol has already seen huge attention to be used in the typical otto cycle engine and in many places is already being blended with gasoline to create a hybrid fuel source.  However, running an engine on pure ethanol is beset by several major obstacles.  Firstly, ethanol is miscible with water at any concentration, which creates long term storage corrosion issues.  In addition, ethanol engines must be designed to expect water vapor unlike their gasoline counterparts.  Ethanol also has significantly different thermodynamic properties than gasoline such as a lower energy density and different vapor properties which would reduce the economical advantage of using ethanol as a primary fuels source.

We propose using a different fuels source to eventually replace gasoline, butanol.  Butanol is a superior to ethanol as a replacement for petroleum gasoline. With a low vapor pressure, high energy density, and a gasoline-like octane rating, it can be blended into existing gasoline at much higher proportions than ethanol without compromising performance, mileage, cold starting, or volatile organic pollution standards.  Blending butanol with gasoline also prevents modifications of the fuel-air ratio and modifications to the fuel system.  Butanol also is immiscible with water at concentrations higher than 7%, alleviating storage concerns.

The Butanerds wanted to further evaluate the use of butanol as a fuel in standard spark ignition engines.  With the assistance of The University of Alberta's Engine Control Lab in Mechanical Engineering we were able to run a peak power test comparing butanol to iso-octane, a standard test measurement.  Each fuel was burned at a stoichiometric air to fuel ratio at 4 different angular speeds.  The experimental setup and results can be seen below.

Genes encoding the enzymes in the ''C. acetobutylicum'' butanoate metabolism pathway were identified using the KEGG database (KEGG number-ca00650: http://www.kegg.com/dbget-bin/www_bget?path:cac00650).

II: Developing butanol tolerance with the mutagenic and toxic compound--Ethylnitrosourea ENU<br>

The concept is to make butanol-agar plates of various butanol concentrations and place an ENU disk in the centre.  We expect two ring-shaped kill zones.  The first where bacteria die due to the toxicity of ENU at the centre of the plate.  The second around the outer edge of the butanol-agr plate where bacteria die due to butanol toxicity.  In between these two zones we hope to see some cells that would be mutated in a benifical way to render them resistant to butanol.

Concurrently, we are investigating the possibiilty of introducing the butanol production pathway into a photoautotrophic bacterium, ''Chlorobium tepidum''. ''C. tepidum'' is a green sulfur bacterium that is strictly anaerobic and uses sulfur compounds as terminal electron donors. ''C. tepidum'' is a moderately thermophillic bacterium, growing at 40 degrees Celsius (104 degrees Fahrenheit), and requires low light conditions for optimal growth. These bacteria grow well in a defined medium, utilizing the reverse/reductive tricarboxylic acid (TCA) cycle to build up carbohydrates from carbon dioxide.  In addition, the genome of this bacterium has been completely sequenced.  For a more comprehensive overview of ''Chlorobium tepidum'' go to [[http://www.bmb.psu.edu/faculty/bryant/lab/chlorobiumtepidum/index.html ''here'']].  Images below from http://www.bmb.psu.edu/faculty/bryant/lab/chlorobiumtepidum/index.html

The advantage of manipulating this organism for butanol production is a matter of energy input and output. Rather than having to utilize vast amounts of food stocks, such as grains or sugars, a photoautotroph will fix carbon dioxide into the complex carbohydrates required for butanol production. Theoretically, if the only fuel on our planet was butanol, and it was produced in this manner, there would be little net carbon dioxide produced.

== '''Modeling Efforts''' ==
 +
 
 +
Initially our plan to model the efficiency of the butanol production hinged on developing a complete model for the entire glucose pathway in an ''E. coli'' cell using Michaelis-Menten kinetics. After further review, this proved to be beyond the scope of our project's timeline due both to the large number of species and reactions present in the system (as well as their non-linear behavior) and the relative difficulty in finding experimental kinetic information for some of the reactions in our pathway. <br>
 +
 
 +
 
 +
Therefore, to obtain a rough "first-order" approximation for the behavior of the pathway, we considered three factors:
 +
 
 +
1) Stoichiometric factors (both redox and carbon)<br>
 +
2) Compared the relative production rates of the various end products of the glucose pathway in ''E. coli'' as found in previous experimentation to the production rates of butanol in ''C. acetobutylicum''. <br>
 +
3) We have also a fuel E. coli Stoichometric Matrix, and intend to stoichiometrically model the system in order to optimize butanol production once the operon is in the system.
 +
 
 +
 
 +
From these factors we can obtain an indicator of how likely butanol will be produced.
 +
<br>
 +
 
 +
In order to further develop the system, we hope a full metabolic stochiometric model can be eventually realized for this project.  This would allow optimization of the system in order to maximize the flux through the butanol pathway.

Background: Biofuels

With growing concerns of global greenhouse gasses, the global energy market is in a continual push for the development of renewable energy sources. Specifically, two fuels have dominated the media: biodiesel and ethanol. However, both of these fuels have shortcomings in terms of being a viable fuel source.


Biodiesel is a fuel produced from the vegetable oils of crops that can be used in an engine system very similar to a traditional diesel engine. However, vegetable oils in crops only make up a small portion of the biomass of the plants, ultimately producing low yields of fuel per acre of crops. As such, it is more economically sound to use these resources for food production.


There has been huge attention to the use of ethanol in the typical auto cycle engine. In many places it is already being blended with gasoline to create a hybrid fuel source. However, running an engine on pure ethanol is beset by several major obstacles. Firstly, ethanol is miscible with water at any concentration, which creates long term storage corrosion issues. Secondly, ethanol engines must be designed to expect water vapor unlike their gasoline counterparts. Ethanol also has significantly different thermodynamic properties than gasoline such as a lower energy density and different vapor properties, which would reduce the economical advantage of using ethanol as a primary fuels source.


We propose using a different fuel source to eventually replace gasoline, butanol. Butanol is a superior to ethanol as a replacement for petroleum gasoline. With a low vapor pressure, high energy density, and a gasoline-like octane rating, it can be blended into existing gasoline at much higher proportions than ethanol without compromising performance, mileage, organic pollution standards. Blending butanol with gasoline also prevents major modifications of the fuel-air ratio and modifications to the fuel system. Butanol also is immiscible with water at concentrations higher than 7%, alleviating storage concerns as well as offering the possiblity of phase separation which would realize huge cost savings in terms of production.


More information on the summary of biofuels viability and the inspiration to our project can be found here.


The Butanerds wanted to further evaluate the use of butanol as a fuel in standard spark ignition engines. With the assistance of The University of Alberta's Engine Control Lab in Mechanical Engineering we were able to run a peak power test comparing butanol to iso-octane, a standard test measurement. Each fuel was burned at a stoichiometric air to fuel ratio at 4 different angular speeds. The experimental setup and results can be seen below.

The Project: Plan B

We propose the use of butanol as the leading biofuel for use in internal combustion engines. Specifically, we intend to genetically engineer Escherichia coli bacteria to convert biomass into butanol for use as an energy source. This will be accomplished by introducing the genes responsible for butanol production from Clostridium acetobutylicum (i.e. endogenous butanoate pathway) into E. coli. Furthermore, we hope to increase E. coli's tolerance to solvents such as butanol.

I: Transforming genes in C. acetobutylicum's butanoate pathway into E.coli
Genes encoding the enzymes in the C. acetobutylicum butanoate metabolism pathway were identified using the KEGG database (KEGG number-ca00650: http://www.kegg.com/dbget-bin/www_bget?path:cac00650). Our cloning stragegy is to incorporate all the genes in a single operon with respective inducible promoter and ribosome binding site in a plasmid. Such construct enables easy transformation of multiple genes simultaneously into E.coli and allows the coordinated expression of genes within the operon.

After receiving the commercially synthesized coding sequences of the genes of interest, the coding sequences are restricted with proper BioBrick prefixes and suffixes out of the original plasmid and cloned into B0034 (ribosome binding site). Double digest (Xba I and Spe I) as well as automated sequencing reactions are performed to verify the proper insertion of the coding sequences and the presence of a ribosome binding site at the 5' end of each coding sequence.

The operon, shown below, consists of all of the genes in the pathway (except E. coli's thiolase). Note that we purposedly added a Histamine tag to the carboxy terminus of each gene product such that we could use Nickel-NTA column to purify the tagged proteins and subsequently analyze protein expression and enzymatic activity.

The Butanol Operon

II: Developing butanol tolerance with the mutagenic and toxic compound--Ethylnitrosourea ENU
The concept is to make butanol-agar plates of various butanol concentrations and place an ENU disk in the centre. We expect two ring-shaped kill zones. The first where bacteria die due to the toxicity of ENU at the centre of the plate. The second around the outer edge of the butanol-agr plate where bacteria die due to butanol toxicity. In between these two zones we hope to see some cells that would be mutated in a benifical way to render them resistant to butanol.

Proposed Butanol-ENU Plate for Mutagenisis of E. coli


Concurrently, we are investigating the possibiilty of introducing the butanol production pathway into a photoautotrophic bacterium, Chlorobium tepidum. C. tepidum is a green sulfur bacterium that is strictly anaerobic and uses sulfur compounds as terminal electron donors. C. tepidum is a moderately thermophillic bacterium, growing at 40 degrees Celsius (104 degrees Fahrenheit), and requires low light conditions for optimal growth. These bacteria grow well in a defined medium, utilizing the reverse/reductive tricarboxylic acid (TCA) cycle to build up carbohydrates from carbon dioxide. In addition, the genome of this bacterium has been completely sequenced. For a more comprehensive overview of Chlorobium tepidum go to [[http://www.bmb.psu.edu/faculty/bryant/lab/chlorobiumtepidum/index.html here]]. Images below from http://www.bmb.psu.edu/faculty/bryant/lab/chlorobiumtepidum/index.html

The advantage of manipulating this organism for butanol production is a matter of energy input and output. Rather than having to utilize vast amounts of food stocks, such as grains or sugars, a photoautotroph will fix carbon dioxide into the complex carbohydrates required for butanol production. Theoretically, if the only fuel on our planet was butanol, and it was produced in this manner, there would be little net carbon dioxide produced.

Modeling Efforts

Initially our plan to model the efficiency of the butanol production hinged on developing a complete model for the entire glucose pathway in an E. coli cell using Michaelis-Menten kinetics. After further review, this proved to be beyond the scope of our project's timeline due both to the large number of species and reactions present in the system (as well as their non-linear behavior) and the relative difficulty in finding experimental kinetic information for some of the reactions in our pathway.


Therefore, to obtain a rough "first-order" approximation for the behavior of the pathway, we considered three factors:

1) Stoichiometric factors (both redox and carbon)
2) Compared the relative production rates of the various end products of the glucose pathway in E. coli as found in previous experimentation to the production rates of butanol in C. acetobutylicum.
3) We have also a fuel E. coli Stoichometric Matrix, and intend to stoichiometrically model the system in order to optimize butanol production once the operon is in the system.


From these factors we can obtain an indicator of how likely butanol will be produced.

In order to further develop the system, we hope a full metabolic stochiometric model can be eventually realized for this project. This would allow optimization of the system in order to maximize the flux through the butanol pathway.
