Genetic engineering lesson
To prepare for a school visit to teach a class about genetic engineering, we held meetings with two professors of our university, Professor Grefen on the 18th and Professor Piotrowski on the 25th of August.
They told us how to explain genetic engineering correctly and we talked about good examples. Also, they gave us the necessary know-how to teach a class. The both of them even provided some of their own materials for us to use. It was really interesting and helped us a lot for our school visit which took place on the 22th of September.
After that, the school wrote an article about our project and the visit.

“Platypus milk from yeast cultures - visit of the iGEM working group in the LK Biology Q2
25 September 2021
Platypuses are primitive mammals, found exclusively in Australia, they lay eggs, have a beak and a beaver-like tail - so far, so good. But who knows that these cute furry animals excrete their mother's milk over their body, and that this milk has a strong antibacterial effect? This peculiarity aroused the interest of the iGEM working group of the synthetic biology course at the Ruhr University Bochum.
iGEM (international Genetically Engineered Machine Competition) is a non-commercial competition for students from all over the world who formulate a project idea in working groups and implement it comprehensively. The task is not only to use genetic engineering methods, but also to generate the necessary funds, obtain equipment, materials and create the needed communication structures.
The spokesperson of the working group, Marius Schnutenhaus, a Waldstrasse high school graduate (2017), comprehensively explained the steps of the project and thus gave an impression of modern laboratory work:
The genes that code for the different proteins in platypus milk are stored in genetic databases. The required base sequences are ordered from specialised suppliers and can then be processed further. These chemical companies often also supply the gene shuttles (e.g. plasmids) needed to insert the genes into microorganisms. The selected microorganisms (in this case yeast) then convert the genetic information into the desired protein. This sounds quite simple at first, but of course it requires precise work and a lot of patience.
For the students of the advanced biology course, there was not only a lot of old and new information about genetic engineering, but also an insight into the study of synthetic biology and, beyond that, into the career prospects of biologists and biochemists.”

Since we wanted to give a good understanding of our project too, we chose to contact a former teacher of our team member and lab leader Marius and ask if the school would be interested in giving us this opportunity. To our delight, we received positive feedback and an invitation to visit an advanced biology course to teach genetic engineering and present our project.
BIOspektrum article
The BIOspektrum is a German magazine that informs about current topics in science and politics. We were given the opportunity to publish our article “Platylicious - Schnabeltier-Joghurt für den Umweltschutz” (Platylicious - Platypus joghurt for environmental Protection) in the September issue of 2021.
The article can be found here.

Maastricht Journal Initiative
We also participated in the Journal initiative from MSP-Maastricht, where we published a paper about our Project. This gave us the opportunity to practice scientific writing and how to present our project.
We also peer reviewed interesting papers from other Teams and got helpful feedback on our own.
Our paper can be found here.

Newspaper article and television appearance
We also tried to engage the public through communicating our project and educating about genetic engineering and thus help remove misunderstandings and preconceptions about GMOs in food production.
To achieve this goal we reached out to newspapers in our area and asked if they were interested in featuring our project.
Two reporters of the “Westdeutsche Allgemeine Zeitung” (WAZ) visited us in our lab, and we talked about our project, answered questions and explained the science behind synthetic biology.

He visited us in our laboratory, and we filmed a short three minutes long video where we showcased our project and showed some lab work we did at the time. The video was aired on 30th September, and we had the opportunity to visit the Lokalzeit Ruhr WDR-Studios in Essen for a live interview.
The television host had interesting questions for Marius, who was chosen to represent our team. We are very grateful to have the opportunity to present our project and synthetic biology to a broader audience.

Survey about milk consumption and flavor
As we didn’t know what flavor we should use for our product, we created a survey to find out what consumers would like. We also asked about their milk consumption habits, such as how often milk products are consumed and if people consume either animal or plant based milk or even both, and we also asked them to tell us the reasons, as it is important for us to know what people prefer.
To promote our survey, we contacted everyone we know and asked them to spread it.
Overall, a total of 292 people participated, and we would like to say: “Thank you’’, because these results can be crucial for our project.
89% of our participants were European, while 11% were from non-European countries. 62% of all participants were 21-30 years old (Figure 6) and 64% were female (Figure 7).

The results indicated that it was very close between only animals with 39% and both with 40%. It was only 21% who preferred only plant based products (figure 10).
Figure 10: Results what people like more: Only animal, only plant based products or both.
The most significant reason to consume only plant based products is for ethical reasons, with 36%. 21% wrote they are vegan, which of course is also connected to ethics. Ecological reasons also played a role with 10%. Only 8% think it tastes better (Figure 12), which is a very low percentage in comparison to the results of only animal products, in which it was the main reason for participants to consume it (Figure 11).
As stated above, almost as many participants as in only animal products chose both. Most people wrote they have no specific reason, they just like both with 28%. 19% are trying to reduce consuming animal products. 12% prefer animal products but are lactose intolerant. Only a few percent consume both out of ethical or ecological reasons (Figure 13).
