A bench-top bioreactor system for investigation of microbial CO2 fixation in dark conditions.

HNEI has research facilities dedicated to bioprocessing and thermal catalysis. Equipment includes 2, 5 and 10-liter bioreactors complete with full process controls as well as a 10-liter three-phase anaerobic digester. The laboratory facilities are also equipped with autoclaves, biosafety cabinets, incubators, thermal reactors, micro and centrifuges, cell disrupters, membrane filtration systems, and freeze-dryers. Advanced instruments used for chemical and physical analysis include UV/VIS spectrophotometer, FTIR-ATR spectrophotometers, GCs with TCD/FID detectors, HPLCs with UV and IR detectors, UHPLC with RID/PDA, PC1 photon-counting spectrofluorimeter, size-exclusion chromatography (SEC), differential scanning calorimeter (DSC), tensile tester, Keyence 3D laser scanning microscope, and various optical microscopes with heating plates, cameras, and fluorescent lenses. Wet chemistry instruments used for measurement of liquid phase metabolites include HACH reactor systems for wastewater analysis, parametic and infrared gas analyzers for gas phase O2 and CO2. Process design, simulation and economic analysis are conducted with computer software (SuperPro Designer).
