Question
Answer
Aerobic Respiration   Metabolic pathways that use oxygen to generate ATP  
🗑
Anaerobic metabolism   The chemical process of maintenance of cells without air or oxygen  
🗑
Aseptic   Sterile, free from bacteria, viruses, and contaminants such as foreign DNA  
🗑
Batch culture   A large-scale cell culture in which cell inoculum is cultured to a maximum density in a tank or airlift fermentor, harvested, and processed as a batch  
🗑
Biomass   The dry weight of an organism or organisms. Can only be experimentally determined by completely drying (and therefore killing) the organism and then massing it on a balance  
🗑
Bioreactor   A container used for bioprocessing  
🗑
Bioprocessing   Using organisms or biologically derived macromolecules to carry out enzymatic reactions or to manufacture products  
🗑
Carbohydrate   A compound containing carbon, hydrogen, and oxygen, with twice as many hydrogens as oxygens; sugar or starch  
🗑
Chemostat   A growth chamber that keeps a bacterial culture at a specific volumeand rate of growth by limiting nutrient medium and removing spent culture  
🗑
Enzymes   Proteins that catalyze biochemical reactions by causing or speeding up reactions without being changed in the process themselves  
🗑
Fermentation   A process used to grow bacteria or yeasts in liquid culture  
🗑
Fermenter   A bioreactor used to grow bacteria or yeasts in liquid culture  
🗑
Fluid Power   Energy transmitted and controlled by means of a pressurized fluid, either liquid or gas. The term fluid power applies to both hydraulics and pneumatics  
🗑
Glycolysis   The metabolic breakdown of glucose and other sugars that releases energy  
🗑
Hydraulics   Uses pressurized liquid, for example, oil or water  
🗑
Incubator   An apparatus in which environmental conditions, such as temperature and humidity, can be controlled; often used for growing bacterial cultures  
🗑
Media   A sterile preparation made for the growth, storage, maintenance, or transport of microorganisms or other cells  
🗑
Molarity   Molar concentration of a solution, usually expressed as the number of moles of solute per liter of solution.  
🗑
Oil Eating microbes   Bacteria that eat oil, hydrocarbons, and other contanimants  
🗑
Pneumatics   Uses compressed air or other neutral gases  
🗑
Process Engineer   The operator of a complex chemical or biological plant, person who works to improve the process by making it more efficient, easier, safet, etc.  
🗑
Renewable Energy   Energy that is captured from on-going natural processes such as production of fuels such as ethanol from biomass  
🗑
Scale Up   To take a biopharmaceutical manufacturing process from the laboratory scale to a scale at which it is commercially feasible  
🗑
Substrate   A surface on which an organism grows or is attached  
🗑
