THU TeamIntroductionAs the school motto “Self-discipline and Social Commitment” reflects, Tsinghua University iGEM 2007 team is focusing on endeavor and creativity as well as teamwork and responsibility in the process of cooperating with the others to accomplish a goal. The team consists of two supervisors, three advisors, eight members and the desire to explore the world of synthetic biology.

Preliminary Proposals
How much can we disturb or control the communication between microorganisms in tremendous amount? Perhaps a chain carrying signals that we want to bruit is possible to be constructed in the society of E. coli. Then we can gain a closer insight into those tiny lives.
According to former work in the realm of Oscillator, we are inspired to design special gene sequence that can endow E. coli periodical reaction in certain forms to certain signals, which can be derived from other cells or be opposed artificially.

TJU TeamTeam one
Team twoIntroductionWe come from Tianjin University, one of the most famous universities in China. Our team is composed of fifteen creative young people with enormous passion for synthetic biology. The solid foundation of professional knowledge provides us firm confidence, and the enthusiastic research spirit gives us the courage to challenge the mystery of science. We believe that everything can be possible with our endeavor and wisdom. Members
Binbin Han PHD of biochemical engineering
Xiaowen Hou major in biological engineering
Prof. X.M. Zhao Lab and fundingProf. X.M. Zhao is kind enough to provide ‘wet’ experiments environment and ‘dry’ experiment equipment for us. Project 1ene circuit The aim of our project is to simulate electrocircuit in series and parallel connection by gene elements. Series circuit and parallel circuit are the simplest circuits in physics. There are three eletments in it: switch, power and resistance. What we should do is to construct three kinds of bacterials functioning as the three elements in electrocircuit, seperately: one for power, the other two for resistances(R1 and R2). Light is used as a switch. The gene circuit is connected when the bacterials are supposed to light so that the flurescence proteins with different colors in the three kind of bacterials are all expressed, while the circuit is cut when we turn the light off. In series circuit, If we cut any of the resistances or power, it will result in the disconnection of the whole circuit, while in parallel circuit, the lack of one resistance will not influence the other one. Three different kinds of HSL are used as the cell to cell signals. Project 2Bacterial neon light In this project ,we use gene circle to create a bacterial neon light with three different colors. the first repressor protein, LacI from E. coli, inhibits the transcription of the second repressor gene, tetR from the tetracycline-resistance transposon Tn10, whose protein product in turn inhibits the expression of a third gene, cI from λ phage. Finally, CI inhibits lacI expression, completing the cycle. The three repressors are connected with red, green, and yellow luc genes (a kind of luminescent gene) seperately. With the oscillation of the gene circle, the three colors of light will show up circularly, just as a neon light. ContactThe following is the contact of the iGEM TJU 2007 team. Your advices and suggestions are welcome and highly appreciated.

USTC TeamIntroductionWe come from USTC, one of the most famous universities in China. We are the combination of the exact tradition of USTC and the exact vitality of the young. Rigorous daily schoolwork has provided us with a solid foundation of basic knowledge, and an innovative spirit enables us to stand on the frontier of the modern science. Our belief is'Never to say failur'.

ProposalDespite the exciting advancement in recent years, phage contamination is still one of the headaches that nowadays the food and fermentation industries mainly confront. Some strains with genotype like TonA is resistant to T1-like bacteriophages, but the productive performance of these strains is low because of the slow growth rates. Therefore, the producer is facing a dilemma: how can we deal with the strains lacking phage resistance, but with high productivity, and strains with certain kind of phage resistance but the productivity of which is rather low.
