Our faculty has ML-1 laboratories and one ML-2 laboratory, but we are only allowed to work in ML-1 labs for which the basic microbiology laboratory rules apply. Internationally, there are strict rules on genetically modified organisms (GMO). A license is required to be allowed to work with GMO’s. Only if the risks to humans and the environment are minimal to negligible, the government grants a license. The rules for working with GMO’s have to be followed by the laboratory researchers. For each laboratory one person is responsible for the compliance to the rules on that specific lab. Dr. L.A. Robertson has the final responsibility for all the labs. This means that she always knows what biological material is used, where and by whom.

Before you are allowed to work in a laboratory you have to pass a Biosafety Test, which includes identifying of possible hazards in a lab.  This includes all the basic rules for researches to be allowed to work on the lab. Subsequently is a “hand washing test” which shows you the correct way to wash your hands. All team members passed this incredibly difficult test successfully! Afterwards we studied the permits needed for our work and what they do and don't allow.

To request such a permit, a research proposal was provided to Dr. L.A. Robertson. The research proposal included a table containing the micro-organisms, plasmids and existing BioBricks we intended to use. To ensure that we’ll work within the permit, there are two lists which state all the allowed vectors and hosts. These lists are provided, just like the permit, by the Dutch Ministry of Housing, Spatial planning and the Environment. During the writing of our research proposal, we constantly verified in these lists if our plans were within the permit. After Dr. L.A. Robertson read or research proposal and verified all the vectors and hosts, she gave us the permission for our project. Now we can finally start our project, informing our BSO Dr. L.A. Robertson regularly on our progression in the lab and what we are planning to do in the near future.

By regulation we are permitted to work only in ML-1 laboratories, and as such we are aware that we will not work with hazardous and infectious host organisms and genes. Specifically, all the genes and devices that we use should be subject to regulations laid down by the Dutch Government. In our faculty of Applied Sciences and more specifically in Kluyver Laboratory of TU Delft, our team is allowed to work only in ML-1 laboratories with organisms labeled H1 and parts which are originated from non-infectious organisms by regulation. All of them are already commercially used systems. As a result, all the parts we will construct can be considered harmless. All our ideas and plans are verified and approved by our BSO.

As mentioned earlier, all our organisms are classified as Risk Group 1, which contains microorganisms with no recogna. While working in ML-1 laboratories, we have to deal with strains which are indicated that they have low existent virulence; however it is not non-existent virulence. These microorganisms are considered not to be hazardous for healthy persons. However, organisms labeled H1 have been shown to possibly have some infectiveness for immunocompromized persons. This seems not to be a problem in our case, because luckily all team members can be considered healthy adults.

On the other hand, regarding the laboratory techniques and chemicals that we are planning to use, there are some aspects that we have to be careful about. For our own safety in the lab we need to be careful with materials such as Bisacrylamide (cross-linking agent for the preparation of polyacrylamide gels) and ethyl bromide (chemical compound of the haloalkanes group). These materials are regarded as “dangerous, potentially carcinogenic substances”. Nevertheless, if everybody works according to a good laboratory practice, there will be no risks involved. Everybody has experience in working with possibly harmful chemicals and the proper caution is taken.

The strain that we use is the E.coli strain K12, which is a specifically weakened laboratory strain. This strain is well-adapted to the laboratory environment, and unlike wild type strains, has lost its ability to compete with natural organisms outside of the laboratory and in human organism. If it were to “escape” it would be completely unable to sustain itself without our nice little media and agar plates. Therefore our E.coli strain poses an absolute minimal threat to the public or the environment.

Finally because our project is basically targeted in fundamental and industrial purposes, the organisms are not designed to be released in the environment! The organisms are designed to be used in a closed system, which of course involve specific rules. This makes our current contribution in synthetic biology lacking of environmental risk.

Also for the Biosafety point of view and as mentioned above, in engineering of organisms it is recommended well-known microorganism to be used. The reason is because there is more knowledge on how internal systems work and intertwine. This will make an ETA and an FTA more effective and therefore the risks will be reduced.

Safety proposal

Biosafety regulations


Our lab is part of the TU Delft Faculty of Applied Sciences and this means all kinds of safety rules apply. These rules are essential for working with biological materials! We must always keep a close watch on if and when we are in contact with what kinds of organisms and act accordingly. On this page we shed a little light on the safety measures.

Since 1997 Dr. L.A. (Lesley) Robertson is the Biological Safety Officer (BSO) of the Faculty of Applies Sciences of Delft University of Technology, she manages biological safety issues. She has knowledge of the laboratory practices and procedures within the faculty and oversees the biological safety program of the faculty.

Our faculty has ML-1 laboratories and one ML-2 laboratory, but we are only allowed to work in ML-1 labs for which the basic microbiology laboratory rules apply. Internationally, there are strict rules on genetically modified organisms (GMO). A license is required to be allowed to work with GMO’s. Only if the risks to humans and the environment are minimal to negligible, the government grants a license. The rules for working with GMO’s have to be followed by the laboratory researchers. For each laboratory one person is responsible for the compliance to the rules on that specific lab. Dr. L.A. Robertson has the final responsibility for all the labs. This means that she always knows what biological material is used, where and by whom.

Before you are allowed to work in a laboratory you have to pass a Biosafety Test, which includes identifying of possible hazards in a lab. This includes all the basic rules for researches to be allowed to work on the lab. Subsequently is a “hand washing test” which shows you the correct way to wash your hands. All team members passed this incredibly difficult test successfully! Afterwards we studied the permits needed for our work and what they do and don't allow.

To request such a permit, a research proposal was provided to Dr. L.A. Robertson. The research proposal included a table containing the micro-organisms, plasmids and existing BioBricks we intended to use. To ensure that we’ll work within the permit, there are two lists which state all the allowed vectors and hosts. These lists are provided, just like the permit, by the Dutch Ministry of Housing, Spatial planning and the Environment. During the writing of our research proposal, we constantly verified in these lists if our plans were within the permit. After Dr. L.A. Robertson read or research proposal and verified all the vectors and hosts, she gave us the permission for our project. Now we can finally start our project, informing our BSO Dr. L.A. Robertson regularly on our progression in the lab and what we are planning to do in the near future.


“Safety Issues” related to our Project


Our Parts:

Working for iGEM is a great opportunity to design your “amazing” new organism and have fun doing that, as in every scientific project. However, there are also safety issues that have to be taken seriously into account. It was very important for us, during the whole design of our iGEM project, to take into consideration all the safety parameters that our project and especially our parts could raise.

By regulation we are permitted to work only in ML-1 laboratories, and as such we are aware that we will not work with hazardous and infectious host organisms and genes. Specifically, all the genes and devices that we use should be subject to regulations laid down by the Dutch Government. In our faculty of Applied Sciences and more specifically in Kluyver Laboratory of TU Delft, our team is allowed to work only in ML-1 laboratories with organisms labeled H1 and parts which are originated from non-infectious organisms by regulation. All of them are already commercially used systems. As a result, all the parts we will construct can be considered harmless. All our ideas and plans are verified and approved by our BSO. (Biological Safety Officer)


Researchers’ safety:

Another safety aspect that we have to be aware of is our own safety in the laboratory, the so called “researchers’ safety”. In this case, we had to verify the safety of our biological material but also the safety of all the techniques and chemicals that we intended to use.

As mentioned earlier, all our organisms are classified as Risk Group 1, which contains microorganisms with no recogna. While working in ML-1 laboratories, we have to deal with strains which are indicated that they have low existent virulence; however it is not non-existent virulence. These microorganisms are considered not to be hazardous for healthy persons. However, organisms labeled H1 have been shown to possibly have some infectiveness for immunocompromized persons. This seems not to be a problem in our case, because luckily all team members can be considered healthy adults.

On the other hand, regarding the laboratory techniques and chemicals that we are planning to use, there are some aspects that we have to be careful about. For our own safety in the lab we need to be careful with materials such as Bisacrylamide (cross-linking agent for the preparation of polyacrylamide gels) and ethyl bromide (chemical compound of the haloalkanes group). These materials are regarded as “dangerous, potentially carcinogenic substances”. Nevertheless, if everybody works according to a good laboratory practice, there will be no risks involved. Everybody has experience in working with possibly harmful chemicals and the proper caution is taken.

Environmental and public safety:

Last but not least, the environmental and public safety was one ofour most serious considerations. In our project, the most important issue we had to consider was the choice of the host organisms that we decided to use.

The strain that we use is the E.coli strain K12, which is a specifically weakened laboratory strain. This strain is well-adapted to the laboratory environment, and unlike wild type strains, has lost its ability to compete with natural organisms outside of the laboratory and in human organism. If it were to “escape” it would be completely unable to sustain itself without our nice little media and agar plates. Therefore our E.coli strain poses an absolute minimal threat to the public or the environment.

Finally because our project is basically targeted in fundamental and industrial purposes, the organisms are not designed to be released in the environment! The organisms are designed to be used in a closed system, which of course involve specific rules. This makes our current contribution in synthetic biology lacking of environmental risk.


Biosafety for the “FUTURE”


The iGEM competition should keep working with well-known organisms. Of course projects where the toxicity of organisms can be studied and be regulated may be also very interesting and with huge contribution in the scientific field that we represent. However, it should be well contained and guided by experienced supervisors and scientists. Students should be well informed on lab regulations, especially when working as interdisciplinary teams.

A categorized and government controlled system of lab experienced certificates should be implemented. This is already in place for nuclear laboratories, but not yet for the biohazard laboratories. This would give more clarity about who is capable to work in such environments, creating also the awareness that these hazards deserve.

An obvious solution is to confirm Event Tree Analysis (ETA) and Fault Tree Analysis (FTA) as a compulsory part of the iGEM-designing phase. This will significantly limit the risks of all iGEM projects and student will learn to take Biosafety issues into account already before they are going to work in the laboratory. Also for the Biosafety point of view and as mentioned above, in engineering of organisms it is recommended well-known microorganism to be used. The reason is because there is more knowledge on how internal systems work and intertwine. This will make an ETA and an FTA more effective and therefore the risks will be reduced.

The last years it is well known that there is a serious debate about the field of synthetic biology, and generally about genetic engineering, and what this area can offer. The way that public addresses that issue is based in the personal knowledge and opinion that every one of us has of the idea of GMOs but it also depends on the media exposure of the topic. It is a novel and “exotic” technique, something that is not naturally occurred. This fact seems to be the source of the majority of the conflicts.

Most of the times, this is the result of the limited and sometimes negative overall media coverage of the topic. The iGEM contest, representing the new generation of scientist working on the field of Genetic Engineering, should make synthetic biology issues more clear to the public.

It is our task while working on iGEM to send out the correct view to the public about the field of synthetic biology and a very straight and easy way to do this is the proper communication between the media and scientists. As a result, it is very important the media and the public are approached carefully and be informed properly.
