SAFETY OF OUR PROJECT

Our project is to create a regulation system of gene expression in bacteria, only create new biobrick without producing any biosynthesis product. So it won't have new risks if we used our part in commerce or industry. We had discussed with National Chiao Tung University Environmental Protection and Safety Center.The committee agree us executing our project without any comment.

ORGANISMS WE USED

NEW OR MODIFIED CODING REGION WE USED

SAFETY PROCEDURE IN OUR LABORATORY

This year, we use E.coli DH5α, a bacteria that classified under Risk Group 1, as our classis. It's a non-hazardous and non-infective bacteria that generally used in labs and biological experiments. The safety problem of products in the project is also concerned. In our design, E.coli is engineered to produce various fluorescence proteins and some plant hormones, which are harmless to human and environment. Even so, we follow the standard safety procedure to guarantee a safe experiment environment without dangers. To sum up, we have confidence that our project will not raise any biosafety issue.

Researcher's Safety

In order to protect our researchers from infecting engineered organisms and contaminating the samples, we strictly require all the researchers to follow the rules:

1. Every participant has read Safety Guidelines for Biosafety Level 1 to Level 3 Laboratory , announced by National Chiao Tung University - Environmental Protection and Safety Center.
2. Researchers are fully trained before doing experiments individually. Teaching assistants will guide and supervise the experiments at the first few times.
3. Researchers must wear on lab coat and gloves while doing experiment.
4. No experiments is allowed to be done outside the biosafety cabinet, in order to minimize the possibility of releasing Genetically Modified Organisms (GMOs) .
5. Before and after conducting experiments, 70% alcohol is applied to sterilize hands, equiptments, platform, or anything direct contact E.coli.
6. Well designed hazard dealing protocol is applied in all labs in NCTU

Pubilc Safety

To ensure that the engineered organisms will not leak out and contaminate the environment, all stocks, wastes and cultures which contacted these bacteria should be sterilized, packaged and executed base on standard decontamination procedures. We also set up a strict door access system, preventing miscellaneous people acquiring E.coli. In fact, E.coli we used in lab is less competitive to wild type, because of the lost of the ability to form biofilms and to thrive in the intestine. As to our product, fluorescent proteins and plant hormones lose their function after autoclaving in high temperature and pressure. So, our project does not raise public safety issues according to above reasons.

Institutional Biosafety Committee

In our university, National Chiao Tung University (NCTU), Environmental Protection and Safety Center (ESC), is strictly responsible for the safety of all labs in the school. What we did in our project follows the rules they announced, and they manage all instruments and chemicals, especially for dangerous and toxic ones. The ESC is supervising our project and our advisors who are in charge of laboratory safety come regularly and check if the rules are fully followed. We started the project only if we got ECS’s permission. In fact, they support our project and think it will not raise any safety issues in terms of researcher, public, and even environment.
