Sustainable ingredients leader Jungbunzlauer is collaborating with the Technical University of Vienna (TU Wien) to support innovative research to optimize citric acid production by refining fungal strains at the newly-opened Christian Doppler (CD) Laboratory.

Citric acid is a versatile bio-ingredient used in industries ranging from food and beverage to pharmaceuticals and nutritional supplements.

“The process of converting sugars into citric acid is biologically complex and involves specific genetic and biochemical pathways in the fungus,” said Professor Matthias Steiger, head of the CD Laboratory. “Our goal is to gain a detailed understanding of these processes to enrich naturally efficient fungal strains, maintaining high production standards for the food sector. We are grateful to the team at Jungbunzlauer for supporting this research.”

Innovating for Improved Sustainability

The research focuses on selecting and enriching fungal strains that naturally evolve towards greater efficiency under controlled laboratory conditions, offering significant improvements in citric acid yield and sustainability.

“We are very pleased to support this important research,” said Anne Wagner, Junbunzlauer’s VP research, development and innovation. “At Jungbunzlauer, sustainability is at the heart of what we do. By partnering with TU Wien and supporting this innovative research, we aim to improve production processes in a way that aligns with our commitment to environmental responsibility.”

The CD Laboratory employs advanced molecular analysis and selection techniques to identify key genetic factors and environmental conditions that optimize the fungus’s ability to produce citric acid. Novel methods for in vivo mRNA measurement are also being developed to measure the spatial distribution of mRNA relevant to citric acid production, further refining the strain selection process.

Looking Towards a Greener Future

Jungbunzlauer says its collaboration with TU Wien and the Christian Doppler (CD) Laboratory exemplifies the power of industry-academic partnerships in addressing global sustainability challenges. The results of this research will not only boost the efficiency of citric acid production, but provide a scalable model for the sustainable bioproduction of other important compounds.
