Professor Esteban Marcellin's research is focused on advance biomanufacturing and systems and synthetic biology.
AIBN’s systems and synthetic biology goes beyond conventional ‘omics studies to understand complex cellular behaviours in unconventional microorganisms. For example, using gas fermentation, we are consuming greenhouse gases (CO and CO2) as feedstock for fermentation and converting those greenhouse gases into valuable chemicals and fuels. The technology enables a decrease in our dependence on finite fossil fuel resources and improves sustainability for Australia and the chemical industry. Our projects aim at producing efficient cell lines to increase yields and productivities of mammalian cells lines for biologics production as well as microbial cell factories. In collaboration with leaders in the industry, such as Lanzatech, Amyris, Zoetis, Dow, CSL and Patheon Thermo Fisher we are applying systems metabolic engineering to enhance yields and to increase the production scope of the advanced biomanufacturing sector.
