Today is our 1st meeting. We are a team of 9 consisting of 2 junior year students and 7 sophomore year students.
Today we discussed about team organization and task allocation. Ting-Ting was given the chance to the team leader while Steven and Li-Yi are the in-charge of system designation. We also plan our schedule so that we could make it in time.
It was quite an awkward meeting because somehow it was like when we were small going to kindergarten the 1st week. Though we study in the same campus, but due to different courses, we barely know each other. But it was very fun making new friends.
2011.06.24
It’s already end of June but we still did not get any professor to be our team advisor. Today Prof. Ingrid from Dept. of Molecular Biology and Human Genetics want to interview us before she promise us to be our team advisor. We present to her our whole project and how our idea comes up. Later on we had a little chat with her on our idea and also the whole iGEM. Finally, she accepts our invitation!
Team organization - checked !
2011.06.27
Summer is finally here! Weather is so hot and humid.
We had lunch together before we start our meeting. We were solving the problem of carbon dioxide produced by oxidation of carbon monoxide. The most ideal method is to use either plants or algae to convert the CO2 to biomass which is then processed to produce biofuels. However after long discussion with Professor Chen, we realized that we couldn’t reach that goal in such short period but we can design the host bacteria to use the Carbon Monoxide as one of the carbon source. It’s not a bad idea after all =D
2011.06.30
We all did some research on how Carbon Monoxide affects human body and what concentration level of CO is a concern. Carbon monoxide exposure levels are measured in parts per million or ppm. Steven and Joanne found out that different country has different standards. It was quite confusing because the figure is of big difference. However, after discussion with professor we knew that the risk allowance is also included in it, which is why the safety limits are not the same. Therefore, we can know conclude that, the safety standard is affected by the ppm of carbon monoxide and also the risk allowance.
We also start to do our powerpoint presentation slide which we going to show during the preliminary round.
Everyone is so focus now! Because we believed together we can achieve more. Hopefully we can keep the spirit up =D
2011.07.04
Today we had our meeting in the afternoon. The weather is so hot. It was like barbeque ourselves under the sun so we decided not to have meeting in the afternoon anymore. The topic today is the oxidation of CO to CO2 – we found out that Rhodospirillum rubrum can undergo Calvin Cycle to obtain their energy from sunlight and use CO2 as their carbon source, however cyanobacteria or other bacteria is needed for CO2 fixation and production of biofuels. But it would be much more sophiscated if we add on the cyanobacteria into the system. Hmmm … looks like we have to improve more on our system design !
2011.07.05
We talked to the microbiologist Prof. Chen CY yesterday evening and stunned us with 3 questions. The time factor, the mutation factor and the gene expression rate. The experiment of CO2 fixation requires at least half a year to complete so we probably couldn’t just simply add in our project. Besides that, we also have to think of the mutation of the gene. If the gene mutated then the product would be useless. And the most important is the rate of the protein to turn fluorescent. Lastly, if the gene size is getting bigger it would be more difficult to insert into the plasmid. Consequently, we would need more time in cloning and that would be time-costing. Uhh … we really need to find the resolution soon ! Any way, Prof. Ingrid is really very busy. We have not see her for the past 2 weeks. Gotta check out with her lab assistant.
2011.07.06
Today we had meeting in the afternoon again. Thanks god the weather is windy. We downloaded all the sequences and CDS of the gene we need. On the other hand we also search the sources of R. Rubrum which we planned to use in our project. There is a few proffesor in taiwan doing the research about R.Rubrum. So Joanne will help the letter to them to request a sample of it. And the worst case we can buy it from biotech corporation. Steven need somebody to be the in-charge of wikipedia. Leo volunteered. Found out that 2 enzymes are available : CODH–Nickel, OM5 –Molybdenum; CODH is has a higher rate of binding with CO, but OM5 can bind with CO in enormous amount at one time. Say no to procrastination ! Next meeting on Friday. A day off tomorrow =D
2011.07.09
Discussion regarding the presentation slide during the preliminary round. Task allocated to all the members. While Joanne and Steven had to write the project proposal ASAP. Not much were done today. But TGIF !! Had some photo session after the meeting. Joanne go crazy with the effect thingy on the MacBook. Stressed up after one week of intensive meeting.
2011.07.12
We are all so excited today because we having a photoshooting session this afternoon. We asked another classmate of us, Jason to be our professional photographer. It looks like all of us are good model. It started to drizzle when we were moving to another spot. Too bad we only can do indoor photoshoot. Nevermind, we can have another one in the laboratory next time. In the evening, we also had a meeting with Prof. Ingrid. We did a rehearsal about our preliminary round with her. We really have to speed up to improve our slideshow so that we could stand a chance in the coming competition.
2011.07.15
We had our second rehearsal. And we checked the email, too bad there’s no reply from the 3 professors who we send them the request letter. I think we should stalk the professor in the facebook.
2011.07.18
We had a quick briefing with Steven today. We just got the instructions to attend a meeting with our organizer on 26th of July.
Our preliminary is fixed on 22th July 12 noon. It’s only a week left, we have to work hard !!
2011.07.20
It’s the final rehearsal before our competition. Everyone is well-prepared already. Today we even wore our formal wear to the rehearsal. Steven and Leo look so smart. Practice makes perfect, now everyone can explain the slide very well. I believed that together we can achieve more.
2011.07.25
We make it to the next round! It was the big day today. The professors are impressed by our idea and really like ours creativity. However, our main problem is still the system design which is that the concentration of Carbon Monoxide which will be the inducer of the operon. Also, another problem is that we have to renew the host bacteria regularly.
2011.07.27
Finally, the deputy director of the national museum of marine biology and aquarium replied us. Too bad he doesn’t have the sample of R.Rubrum. Anyway, we’re quite motivated by his words. Thanks Prof. CS Chen
