Heterogeneities - A key for understanding and upscaling of bioprocesses in up- and downstream

The "Himmelfahrtstagung" – a 3-day annual conference happening the week before Ascension Day – has been the main event for Bioprocess and Biochemical engineers in Germany since more than 30 years. In the last years the internationalisation of the conference is continuing unabated, leading to an increased exchange with international colleagues.

The overall performance of bioprocesses is influenced by heterogeneities in all steps of the production process. Heterogeneities of substrates, culture conditions, microbial populations and products have been the subject of intensive research, but the real impact on bioprocesses remains poorly understood. On the one hand, the lack of understanding mirrors the difficulties in monitoring and modelling heterogeneities under dynamic process conditions. On the other hand, their controlled use offers great potential for bioprocess development, for instance by installing mixed cultures for the production of rare products. The “Himmelfahrtstagung” 2018 discusses concepts of wanted and unwanted heterogeneities focusing on the complete process chain from the cell to the product.


Substrate heterogeneities
Mixed cultures and population dynamics
Reaction engineering of heterogeneous processes
Product heterogeneities
Handling of heterogeneities in up- and downstream processing
Modelling of heterogeneities
Open topics - New Developments presented by young researchers

Special features of this conference are the high number of participants from industry, an open culture of discussion amongst the participants as well as sufficient time for the scientific exchange. Finally, as second essential pillar besides the core topic, the ‘Himmelfahrtstagung’ serves as a platform for young scientists to present their results to the scientific community.

Search / advanced search of the idw archives
Combination of search terms

You can combine search terms with and, or and/or not, e.g. Philo not logy.


You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).


Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.

Selection criteria

You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).

If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
