1. technique; in case of applying on surfaces, LALF protein can work like a new sterilization material like gluteraldehyte or alcohol that are commonly used for hospital and lab sterilization.
2. Alternative cure for septic shock; after gram negative bacterial infections; LPS, which is the main component of cell wall of gram negative bacteria, can cause deathly conditions that is generally called “septic shock”. In our project, our LALF protein binds this material strictly, thus LALF can be used as an alternative cure method for such condition.
3. Possible new structure of antibiotic-like drug; antibiotics commonly effect on production of cell wall of bacteria. This is done by inhibiting the source of production. On the other hand, our LALF protein directly binds the cell wall material and stops the bacteria growth. Thus, a new antibiotic like drug made of LALF may be produced and used in some infections.
4. Possibility of producing longtime sterile layers; if any kind of object is produced by covering with LALF, that object can stay sterile for long time because of gram negative bacteria protection of LALF. In case of a possible infection on surface, LALF will stop bacteria growth.
5. Alternative cure method for bacterial diseases; diseases like urinary system infection or gastritis are caused by gram negative bacteria. In the course of applying our bacteria that produce LALF in the infectious cite, infection of harmful bacteria can be prevented or stopped. This may suggest an alternative cure for such diseases.
On the other hand, our secondary protein, reflectin, can be used in varying applications.
1. Camouflage material; this protein allows its host, cephalopod, to hide when cephalopod hunts or to defend itself from its hunters. In the course of development of reflectin protein, a new camouflage material may be produced for humans.
2. New material of dye for varying applications; Dye that changes its color can be used almost every colorful application. From fireworks to wall paints, from windows of buildings to road signs, this ability can be very useful.
3. Possibility of producing specialized light colors; in some circumstances, a unique light color may be necessary in order to gain maximum output like in greenhouses or dark rooms in photography industry. Reflectin reflects the light by changing its wavelength; therefore the light that is reflected has only one color. This ability can be applied in such application that mentioned above.
COLLABORATION
With friendly communications teams can take some useful advises and learn some
important points. Also with helping to other groups friendly feelings increase
and the team’s motivation increases. During our lab working we were always
keeping touch with other teams. We were helping each other and making some
activities together.
We helped to Bilkent_UNAM_Turkey team when they needed our part 1001 and they
helped to us with giving LB Agar. Also the Team Michigan asked helping to us
about board game. We designed the Canvas Town Game and the Team Michigan wanted
some points about preparing and designing. And we were being glad to help them.
Association of Synthetic Biology – METU-Ankara Team invited our team to
Synthetic Biology Turkey Meetings 1.0 of Igem Turkey Teams. This meeting was
really funny and informative.
We are planning a little tournament of Canvas Town Game in the Asia Religion
Jamboree. For this organization we help from Religion Asia Organization
Committee and they helped us very quickly and politely.
For the tournament four teams will determine with drawing. 2 teams will play
together and the other 2 teams will play together. Just 6 persons can play our
game so every team should play with their 3 members. Then the winner teams will
play together in the end of this game 3 finalist member of the last winner team
will be presented.
With these activities we were really enjoyed and informed.
For our project lab executions;
1. LALF based anti-LPS factor system has been worked expectedly
2.we have constructed and submitted 12 biobrick. Three devices working in two for
B.subtilis one for E.coli work expectedly.
3. Our B.subtilis specific promoter with SacB- extracellur signal- has been seen
working well.
4. We have synthesized Reflectin 1a protein in E.coli; however, because we did not
have enough time to purify it to visualize via aid-eye, we could not use
Reflectin 1a device as biosensor for our lalf-LPS interaction in B.subtilis-
E.coli mixed culture.

There are b.subtilis with LALF in our B1 plate and b.subtilis without LALF in our B2 plate.For working of our LALF protein ,count of e.coli with RFP in B1 is lower than B2.
https://static.igem.org/mediawiki/igem.org/f/fd/Sss2.png
We spread fresh E.coli which produce RFP and put them onto 100uL Bacillus Subtilis supernatant which include LALF (plate D1) and no LALF protein producing Bacillus Subtilis supernatant(plateD2).As you can see where Bacillus supernatant with LALF exist ,there wasn’t any E.coli with RFP.

We saw that size of colonies with LALF protein is smaller than size of colonies without LALF protein and also antibiotic didn’t changed the results.
THE SUICIDE EXPERIMENT OF E. COLI
IPTG was caused of suicide of E.coli.Our promoter is IPTG inducable.So when we added IPTG in the media LALF synthezised.Result of this experiment we can say that E.coli kills itself.
For Human Practice; We have performed the activities as follows;
1. Providing Sporocide Method for prevention from spores of B.subtilis in further
B.subtilis synthetic biology project.
2. On the other hand, our secondary protein, reflectin, can be used in varying applications.
3. Preparing a novel board game `Canvas Time` to inform people from any distinct
education level about features of our project, laboratory equipments and
interesting Biobrick of iGEM competition.
.
4.Performing open-lab to public meetings such as gifted children studying in
several schools of Ankara, undergraduate students from Hacettepe University
Medical School and postgraduate students from Ankara University Medical School
5.Kindergarten synthetic biology trip to teach synthetic biology to five-year-old
children.
