BTE - Unit 4

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
