==Introduction==

Our ''Bee. coli'' expresses some antimicrobial peptides such as defensin and abaecin to fight against ''Nosema cerenae''. There is probability that ''Bee. coli'' contaminates the natural environment and cause death to other species. Therefore, light-induced lysis system was created to ensure our ''Bee. coli'' only lives inside of the bee.

We chose to use [http://parts.igem.org/Part:BBa_K592016 K592016] as our light sensing device. [http://parts.igem.org/Part:BBa_K592016 K592016] consists two parts: YF1 and FixJ. YF1 IS a blue-light sensor protein. It works in conjunction with its response regulator, FixJ. When exposed to blue-light, they can activate [http://parts.igem.org/Part:BBa_K592006 K592006], the blue-light sensing promoter.

The lysis device is composed of promoter [http://parts.igem.org/Part:BBa_K592006 K592006], the blue-light sensing promoter, and the lysis protein K896999, which is a lethal 91 amino acid membrane protein that induces lysis in ''E. coli''.

All the biological materials used in our lab are safe to the workers in the lab. Every species we worked with belongs to BL1.

[http://parts.igem.org/Part:BBa_K592016 K592016] is cloned after constitutive promoter J23102, so the proteins YF1 and FixJ were continuing produced. When exposed to blue light, the inactive YF1 and FixJ will be change to their active form and induce the downstream gene of promoter [http://parts.igem.org/Part:BBa_K592006 K592006]. In our circuit, the lysis protein K896999 will be produced and kill our Bee. coli which escaped from the midgut of a bee.

Every species we worked with belongs to BL1. They do no harm to human.

'''Risks to the environment, if released by design or by accident?'''
 +
 
 +
Every species we worked with belongs to BL1. They do no harm to the environment. In addition, we have designed a lysis system to ensure our genetic modified E. coli will not survive in the natural environment.
 +
 
 +
'''Risks to security through malicious misuse by individuals, groups, or countries?'''
 +
 
 +
All the biological materials used in our lab are safe, and all the products of the coding sequences are innocuous to human, so the risk of malicious misuse is low.
 +
 
 +
==If our project moved from a small-scale lab study to become widely used as a commercial/industrial product, what new risks might arise?==
 +
If our design works and is introduced into a commercial/industrial product, it means the bees will be immune to certain pathogens. This might exert pressure on the survival of these pathogens. Also, pathogen-resistant bees would threaten the survival of natural bees.
 +
 
 +
==Does our project include any design features to address safety risks?==
 +
Light-inducible lysis system is created to ensure our Bee. coil only lives inside of the bee. In addition, we have decided upon encapsulation as being the method to send our Bee. coli into the bee. Since the capsule will only dissolve in a bee’s gut, our Bee. coli will not wantonly spread.

We received safety training by our instructors according to the Occupational Safety and Health Act of our country. [http://ces.web.ym.edu.tw/front/bin/ptlist.phtml?Category=18 Our institution’s safety training requirements]
