Multiscale Bioreactor Cultivation
The ABF has multiple scales of integrated bioreactor cultivation equipment ranging from the microscale BioLector Pro systems (2 mL cultivation volumes), more than 30 0.5-L fully controlled bioreactors, multiple 2 L, 5 L, and 10 L scales, up to 100, 1,000, and 9,000 L reactors in the Integrated Biorefinery Refinery Facility that opérate on an as-needed basis. These include aerobic and anaerobic processes and are routinely used for multi-omics investigations of non-model strains on feedstocks ranging from clean sugars to biomass hydrolysates to non-standard substrates (e.g., waste gas, lignin-derived liquor, etc.). In situ product recovery is also available for bench scale units. This capability benefits the ABF mission by enabling rapid strain evaluation and multiscale, multi-omics investigations of non-model strains.
