9/2 - Plans for Asia Jamboree

  • 14 members have decided to participate in the upcoming Asia Jamboree held in Hong Kong.
  • We decided that each member should book an airline ticket separately, because of the difficulty in booking seats for 14 people.
  • We have reserved rooms for 14 people at Regal Riverside Hotel.


9/18 - Briefing on experiment results

  • Overall result is as described below.
- It did not turn out very well as detection of hydrocarbon failed.
- We are not certain of the reason for the failure, but it must be either the compound's concentration was too minute to be detected or it was simply not produced.
- If detection failure is due to low concentration of the compound, we will have to concentrate the culture medium to increase the amount of hydrocarbon.
- TLC will not be useful for this task, so we will have to use GC to detect.
- The reason for using E.coli BW25113 is because of their promoter, Pbad. Bacteria that utilize Pbad utilizes arabinose as an inducer, and is not able to metabolize it.
  • To Hong Kong, one of our advisors, Han-Sung Roh will accompany us.
  • We formed teams for poster and powerpoint design, and organization of experimental results.

9/30 - Almost finished..

  • Current situation
- Codon optimization failed, resulting in low fluorescence
- We thought about using triton x-100(a type of detergent) on E.coli, which theoretically will weaken its membrane, letting hydrocarbon diffuse more easily. Our advisor however did not approve of the option.
- Other options available are
  1. Extraction from the media
  2. Extraction through cell lysis
