We created an <i>E. coli</i> for long distance communication.

<i>Communicheria coli</i> has light sensors constructed using the light receptor domain of bacterial sensory rhodopsin or the cyanobacterial green light sensor CcaS. In response to light signals, cells will induce their own lux operon to send the message to other distant cells, for example in a separate flask, which will in turn relay the message to other distant cells.

To improve the effectiveness of our new signal delivery system, we set out to enhance the light intensity, change the light color, and shorten the response time.

<p>  We will only use typical laboratory E. coli strains (e.g., DH5α) and the engineering experiments we plan to carry out will not introduce any genes that are related to pathogenicity or virulence, or confer any selective advantage were they to be inadvertently or intentionally (maliciously) released into the environment.

<br>  Our laboratory work will be carried out in the laboratories of Prof. Sode (Chief instructor), Prof. Ikebukuro (instructor), Associate Prof. Tsugawa, and Assistant Prof. Ferri (Organizer), which have a biosafety level 2 facility to handle microorganisms and perform genetic engineering experiments.

<br>No,they don’t. Our BioBrick parts do not possess any safety risk for environment and researches. We will make a new BioBrick part that emits bioluminescence. This part is natively expressed in Photobacterium that is non-harmful marine bacterium and we will clone it from that bactera. We are also trying to make light receptor to regulate gene expressing network. We will use BioBrick parts that have already registered as a material to make the network. Thus our new BioBrick part will not raise any safety issues.

<br>Yes, our institution has own biosafety rules. The Gene Research Center of the Tokyo University of Agriculture and Technology Research Center for Science and Technology [http://www.tuat.ac.jp/%7Eidenshi/index.html (only in Japanese)] deals with biosafety issues. All students have to read the provided guidelines and apply for permission to do genetic engineering before we actually start experiments. All our members had read the guidelines and signed for agreement, and we all have been permitted to carry out genetic engineering experiments.

We did not discuss our project directly with our Institutional Biosafety Committee, but we do follow their regulations and guidelines. Our instructors are monitoring our experiments closely, and they have not identified any safety issues.

<br>We think that there is a need to consider safety in three different aspects: researcher’s safety, public safety, environmental safety.

<br>Finally, for environmental safety, we should make a check list that each team MUST check, before carrying out any experiments or registering new iGEM parts.
