General introduction to symposium
Chain-elongation bioprocesses are part of the carboxylate or waste-biorefinery platforms. Chain elongation is emerging as a pertinent bioprocess within the Circular Economy to recover resources. Microbial chain-elongation processes allow the conversion of numerous (in)organics feedstocks (from C1 compounds onwards) into a variety of fatty acids or carboxylic acids, alcohols, alkanes, and other biochemicals. Currently, organic waste streams are digested into methane, which is typically converted into electric power, or even just flared off. Chain elongation does allow utilization of such waste streams into more valuable products. Various products are formed with diverse properties, which allow numerous applications (e.g., animal feed, antimicrobials, biofuels, platform chemicals). Pioneering research work and the current expansion of chain elongation research is leading towards mature applications. Fundamental research, system analysis, separation technology development, as well as bioprocess engineering is ongoing. Several companies performed pilot tests and are making great progress to scale-up specific chain elongation bioprocesses. We are at an excellent moment in time to bring together the research community to share and connect with the goal to further develop chain elongation into an industrially relevant biotechnology production platform.
Themes
All topics related to chain elongation are welcome and are categorized in the following 3 domains:
Biorefinery development & integration in Circular Economy
to include CO2 capture, pre-treatment, separation, purification, conversion of chain elongation products, application, LCA, TEA, system analysis, or pilot-studies and beyond.
Bioreactor engineering and bioprocess development
to show news on feedstock use, products, selection pressure, operating conditions, bioreactors, modelling, etc.
Microbial physiology, pathways, informatics, genetics
to gain insight about microbiomes and pure- and co-cultures and additional in-depth analysis of the biological fundamentals such as microbial physiology.
