Safety Regulations
All personnel receives a tour and are informed of the rules upon entering the lab, the main rules include:
- No running, sudden moves within the lab.
- No eating within the premises of the lab.
- All experiment waste must be thrown in a special bin then put through a machine for sterilization.
- All pipettes must be sanitized after use.
- All equipment use must follow the using manual.
- Performing experiments with a pipette while wearing a lab coat and gloves.
- To enter the laboratory, all personnel must wash hand, as well as wear full lab suits and shoes.

The BIOLAB of Mingdao High School.
Eating and Drinking are not Allowed in the Lab.
The Laminar Flow Clean Bench in the BIOLAB, MDHS.
Warning Signs are Posted in the LAB.
The Emergency Eyewash and Autoclave in the BIOLAB, MDHS.
Our Goal
High concentration of carbon dioxide in enclosed space make people feel sleepy and even dizzy. While driving, drivers may fell asleep, causing accidents to happen. To solve this problem, we plan to use the high photosynthesis efficiency of Cyanobacteria to reduce the concentration of CO2. But the solubility of CO2 in water is not high, so we modified bacillus to produce CA, which can increase the solubility of CO2 in water.
Possible Risks
Organisms Used
E. coli DH5alpha, Bacillus subtilis (Generally Regarded As Safe (GRAS) Bacillus subtilis 168) 168; organisms: Synechococcus elongatus PCC 7942, Spirulina spp.
Risks of Selected Organisms
We use two kinds of algae: Synechococcus elongatus PCC 7942 (non-toxic lab strain, recognized as a safe organism and exists in nature) and Spirulina spp (edible food supplement), and they will not pose a threat even if it escapes from the lab.
Organisms Used As Chasses
- Escherichia coli: E.coli DH5 alpha
- Bacillus subtilis
Risks of Chassis
Bacillus subtilis (Generally Regarded As Safe (GRAS) Bacillus subtilis 168) 168. The cell lines and E.coli strain are recognized as Biosafety Level 1 by US. public Health Service Guidelines and pose less risk to humans, which consistently cause disease in immunocompetent adult humans and present minimal potential hazard to laboratory personnel and the environment.
Experiment Design
We prepare the culture media with baking soda, liquid fertilizer, leaf fertilizer to adjust the ratio and change the illuminance, temperature to find out the appropriate environment for the algae.
Risks of the Experiment
Our experiment only compares the growth of algae under different conditions and the solubility of carbon dioxide, so it will not pose any danger.
Project Usage
- In a consumer product that ordinary people buy
- In a small enclosed device
Risks of Usage
The device we design only contains two organisms: algae and CA.Even if the device is unfortunately broken,the former won't pose a threat to the environment. While the latter will deteriorate naturally and die.Since the organisms we use won't have any negative effect, safety.security or ethical risks wouldn't be involved.
Risks Management
Biosafety Level 1
Expert Assistance
Dr.Pei-Hong Chen will oversee us when we are doing the experiments. He had a PhD degree in Molecular Biology and is familiar with synthetic biology experiments. Also,he have instructed our school's iGEM teams for years.
