  ④ Connect electrode and wire with silicon waterproof adhesive.<br>

            　(We used 2cm*5cm carbon paper with coated back)<br>
+
−
    ⑤ Attach ①, ③, ④ with silicon adhesive. You should paste it very well. <br>

−
          　Two 50mL tube's cap should be arranged opposite. 50mL tubes will be linked from 　outside.<br>

    ⑥ Prepare catholyte and anolyte at 50mL tube each. <br>

      ⑦ Add 175mM Sodium Chloride and Agar(15g/L) in DW, and autoclave it. <br>

          　Next, put a lid on ①'s 15mL tube and fill it with salt bridge solution.<br>

<p> <font size=4>      ① Make a pure culture of bacteria(MR-1, BW25113, BL21, etc) in LB solid medium 　with antibiotics. You can use ampicillin for culturing <em>Shewanella oneidensis</em> MR-1.<br>

      ② Make a seed culture with 4mL LB culture medium from single colony, add 　antibiotics, and culture 12 hours. <br>

−
      ④ Put the cell down using centrifuge(3,000 RPM, 20 minutes, and 4°C).<br>
+
−
      ⑤ If you need cell disruption, use sonicator(ultrasonic processor). Turn on 2 second, 　turn off 10 second for 1 minute. Total time is 4 minutes. <br>
+
−
      ⑥ Add mediator(30μM methylene blue) and substrate. It is convenient if you prepare 　mediator as a stock solution.<br>
+
−
      ⑦ Put 30mM Sodium ferricyanide(electron acceptor) in anolyte.</font><br>

<p> <font size=4>      ① We measured voltage every single minute by an electric measuring circuit using 　potentiometer(1,000 ohm) and Keithley Digital Multimeter <br>

Collaborations

Collaborations

Korea_U_Seoul had collaborated with ‘KoreaSonyeodul team from Hankuk Foreign Language High School. ‘KoreaSonyeodul’ is a team made up with 7 high school girls, and this year is their first time participating iGEM. We, Korea_U_Seoul team has participated iGEM since 2009, therefore our persistent experience on iGEM and synthetic biology-related activities could help them starting things up, through this collaboration.


The collaboration was mainly proceeded in two categories: mentoring new high school team, and experimental exchanges.


1. ColegioFDR_Peru

The members of KoreaSonyeodul came to our lab to look around and have a meeting with our PI. They consulted us about their project, and we helped them to schedule their experiments. Since they did not have their own lab, they shared the lab with us. They never had any experience with lab work such as cloning, so we taught them how things are done. We taught and helped with their part cloning(Restriction enzyme cloning) and LIC cloning. We also helped the with their part registration and submission.

2. Manchester

The members of KoreaSonyeodul came to our lab to look around and have a meeting with our PI. They consulted us about their project, and we helped them to schedule their experiments. Since they did not have their own lab, they shared the lab with us. They never had any experience with lab work such as cloning, so we taught them how things are done. We taught and helped with their part cloning(Restriction enzyme cloning) and LIC cloning. We also helped the with their part registration and submission.

3. Gifu

The members of KoreaSonyeodul came to our lab to look around and have a meeting with our PI. They consulted us about their project, and we helped them to schedule their experiments. Since they did not have their own lab, they shared the lab with us. They never had any experience with lab work such as cloning, so we taught them how things are done. We taught and helped with their part cloning(Restriction enzyme cloning) and LIC cloning. We also helped the with their part registration and submission.

4. NCTU Formosa

The members of KoreaSonyeodul came to our lab to look around and have a meeting with our PI. They consulted us about their project, and we helped them to schedule their experiments. Since they did not have their own lab, they shared the lab with us. They never had any experience with lab work such as cloning, so we taught them how things are done. We taught and helped with their part cloning(Restriction enzyme cloning) and LIC cloning. We also helped the with their part registration and submission.
