Profile:In synthetic biology research, biosafety and biosecurity are critical aspects that cannot be overlooked. To ensure the progress of our project, protect the personal safety of researchers, maintain the normal operation of the laboratory, and prevent public health and environmental safety issues, our team has established a comprehensive safety system. This system primarily includes laboratory safety, biosafety and related regulations, our safety measures, and the biosafety and ethics white paper that we co-authored with the iGEM team JLU-NBBMS. Through the following explanations, we hope to provide a deeper understanding of the safety of our project and biosafety standards, fostering a safe, harmonious, and orderly research environment.
First, before entering the laboratory,
we carefully reviewed the " Safety Manual of South China University
of Technology Laboratory " [1]. Then, our instructor, Alexander
Tjahjasari, provided us with laboratory safety management training,
covering basic safety precautions, including but not limited to:
(1)Smoking, eating, and wearing contact lenses are prohibited in the laboratory;
(2)Appropriate protective equipment must be worn: lab coats, gloves, masks, and
goggles when necessary. Wearing shorts, skirts, slippers, and leaving long hair untied are not allowed;
(3)Reagents and instruments should be returned to their original place after use;
(4)Waste generated in the laboratory must be classified and disposed of according
to regulations, especially waste containing bacteria or other microorganisms, which should be autoclaved before disposal;
(5)Avoid working alone in the laboratory as much as possible;
(6)Ensure the safety of water, electricity, and materials in the laboratory
before leaving, and maintain personal hygiene;
(7)In case of an accident, effective emergency measures should be taken
immediately to control the scope of impact, and report to the unit
leadership, the University Laboratory and Equipment Management Office,
and the Security Office.
We were also introduced to the usage protocols of equipment such as microscope, autoclaves, clean bench, and centrifuges, and practiced operating them.
Our laboratory safety management complies with the "Laboratory Safety Standards for Higher Education Institutions" [2] and aligns with Article 35 of the "Biosecurity Law of the People's Republic of China," which states, "Units engaged in biotechnology research, development, and application activities shall be responsible for the safety of their biotechnology research, development, and application, take biosafety risk prevention and control measures, establish systems for biosafety training, tracking inspections, regular reporting, and strengthen process management" [3].
(1) Raw Material Safety:
We purchased quality-inspected
dried kelp from a licensed online store with a business license and a food
business permit. The kelp originates from Fujian Province, China, and
is used as a fermentation raw material without any genetic modification.
(2) Strain Safety:
The strains we use are
DH5α Escherichia coli from the K-12 lineage and PK2 Saccharomyces
cerevisiae. The K-12 E. coli strain is a non-pathogenic strain classified
as Biosafety Level 1 (BSL-1) and is included on the whitelist.
Saccharomyces cerevisiae is an opportunistic pathogen that generally
does not cause disease. Although PK2 S. cerevisiae is not on the whitelist,
we have submitted a check-in form for it. Both K-12 E. coli and PK2 S.
cerevisiae are not listed in China's "List of Pathogenic Microorganisms
Infectious to Humans" [4].
(3) Product Safety:
In the production
of limonene, we conduct quality monitoring of the product, including
testing limonene purity and checking for harmful substances, to ensure
it meets relevant quality standards. When it comes to limonene itself,
recent studies on limonene safety have not found significant impacts on
human health, so limonene is generally considered safe for use in the food
, chemical, and pharmaceutical industries. However, the environmental
impact of limonene is still unclear, and further research is needed to
assess its behavior and potential effects in the environment.
(4) Gene Editing Safety:
Legal regulations
and requirements concerning gene editing, including the World Health
Organization's recommendations on gene editing, China's " Regulation of
the People's Republic of China on the Administration of Human Genetic
Resources" [5], Article 1009 of the "Civil Code of the People’s Republic
of China" [6], and the "Biosecurity Law of the People's Republic of China
" [3], primarily focus on the control and restriction of human gene
editing. Currently, we have not found specific legal regulations for gene
editing in S. cerevisiae. We believe that the gene editing of S. cerevisiae
in our research is feasible and complies with the "Regulations on the
Safety Management of Genetic Engineering" [7] and Article 34 of the "
Biosecurity Law of the People's Republic of China," which states,
"Biotechnology research, development, and application activities should
comply with ethical principles" [3].
To prevent environmental contamination caused by the escape of strains, all operations involving E. coli and S. cerevisiae are conducted within the laboratory. When observing yeast cells under a microscope during our HP activities, we use food-grade wild-type yeast that is commercially available.
Profile To enhance biosafety awareness
and strengthen people's understanding of biosafety and ethics, we actively
participated in the initiative led by the JLU-NBBMS team to compile a
Biosafety and Bioethics White Paper. This activity brought together
multiple teams from different tracks to co-author the white paper,
showcasing each track's unique biosafety and ethics knowledge while also
introducing their respective project designs. Our contribution to the
Biosafety and Bioethics White Paper reflects our learning from previous
experiences, further exploration and innovation within our track, and
guidance and inspiration for future iGEM teams.
