TalTech Science Day 2023 was a success!

The Science Day event at the Department of Chemistry and Biotechnology took place on April 28, and our research group organised a workshop Future Food From Microbes for the 2nd consecutive time. This year, participants had an opportunity to take part in guided experiments in our laboratories on fermentation technologies and metabolic engineering, and engage in stimulating discussions with our team members. Anyone interested in molecular biology, bioreactors, or other biotechnology disciplines was offered something interesting.

For the participants, it was a perfect chance to learn, explore, and interact with scientists who share enthusiasm for science. For us, the Thanksgiving celebration served as a wonderful opportunity to reflect on the achievements and milestones we reached during the Science Day. We are truly grateful for the organisation by the department, which enabled us to create an engaging and enriching experience for the high school students. We look forward to future events that will continue to inspire and ignite the curiosity of young minds!


TalTech Science Day 2022

On April 29, TalTech Science Day 2022 event took place at the Department of Chemistry and Biotechnology. Food Tech and Bioengineering group organised a workshop “Future food from microbes”. The workshop was devoted to the production of bread and introducing yeast-based cell factories. Participants were introduced to bread baking technologies and experiments improving nutritional value of bread and beyond. The general feedback of the workshops was very positive, 86 % of participants graded it with 9 or 10 in a 10-point scale. More about the workshop, in pictures.

Altogether, Science Day 2022 at Department of Chemistry and Biotechnology offered 19 different workshops that were attended by 89 participants. Majority of workshop participants were high school students, but almost every 4th participant was from outside educational system. Next time it is going to be more focused on high school students and is planned for the next year 2023.

Seminar by Dr. Francesco Gatto, co-founder and CSO of Elypta

In this seminar, Dr. Francesco Gatto illustrates how his group investigated regulation of cancer metabolism using systems biology approaches leading to the discovery of potential cancer biomarkers for early detection. The talk further focuses on the challenge to translate fundamental discoveries in clinical practice and the foundation of Elypta – a start-up university spin-off that is executing this transition.

Estonian Bioeconomy conference

Collaboration project between TalTech, University of Tartu and Life-science University together with three Estonian ministries  – ADDVAL-BIOEC – Added value in Estonian bioeconomy – with a strong contribution also from our Bioengineering group is finishing. The collected research will be presented at the conference on October 26th, 2021, at Erinevate Tubade Klubi, Telliskivi 60-A1, Tallinn (event language is Estonian).

Upcoming Guest Seminar about Living Materials

During his research visit at TalTech, our partner from ALU Freiburg, Tobias Butelmann, will give a seminar (seminar room SCI-109 or online here) about living materials and the current project about Local Electron Delivery in Bioinks for Efficient Yeast Cell Factories. The seminar will be publicly available. Since this project is highly interdisciplinary, we invite all interested people to join this seminar!


Date: 06 August 2021, 11:00 – 12:00.



Abstract: The need for sustainable processes to produce value-added chemicals and materials displays a major challenge of our time. Engineered microbes have the proven power to solve these challenges, as more efficient processes are required in terms of the cell factory as well as the cultivation performance. Bioprocesses currently used in industry are primarily based on batch and fed-batch mode, where yields and productivities have peaked and require technological innovations to uplift this cap on productivities. Additive manufacturing technologies can provide opportunities to move beyond traditional processes and empower a new industrial revolution. 3D printing can be applied together with engineered microbes to print living materials with superior properties to common suspension cultures used in biorefineries. Those living materials consist of a bioink that encapsulates the host organism – a cell factory for the desired product.

One bottleneck in engineered microbes is the regeneration of co-factors, which are critical for their efficiency. To overcome this, special conductible bioinks for living materials can be designed that help embedded microbes by the delivery of electrons for co-factor regeneration. The successful implementation of such a platform has the potential to increase the efficiency of engineered microbes by multiples and, hence, create sustainable biorefinery processes.
