WebOxygen uptake (VO 2) is the amount of oxygen that the body takes up and utilizes. This is an outcome used in exercise physiology as it is reflective of the oxygen uptake at the … WebOxygen Utilization Rates Below the Euphotic Zone The idea here is that if waters on isopycnal (or neutral) surfaces can be dated using this “age”, the rate of O2 consumption …
WebThe rate of oxygen utilization (/ ) is given by the rate of diffusion of oxygen across the exterior surface of the bead. [Pg.48] Low utilizations, particularly oxygen utilization, yield high performance. Low utilizations, however, result in poor fuel use. Optimization of this parameter is required. WebMar 27, 2024 · This is an average rate of oxygen utilization of 2.5 × 10-18 mol cell-1 s-1, i.e. 2.5 amol cell-1 s-1. Cells have a wide range of oxygen utilization, depending on cell type, function, and biological status. Measured rates of oxygen utilization by mammalian cells in culture range from <1 to >350 amol cell-1 s-1.
Oxygen utilization rates of cell lines typically used in biomanufacturing Due to its low solubility in liquid phase and increasing metabolic consumption by the cells with time, oxygen is supplied continuously to the cell culture. Oxygen supply is carefully controlled for optimal cell growth by manipulating bioreactor … See more In cell culture, oxygen is a key substrate for growth, production, and maintenance activities. Cells obtain their oxygen in free and noncompound forms, called dissolved oxygen (DO). One of the most important functions of … See more Because of this association with cell density, kLa values are particularly useful in the following scenarios: See more Any change to process and engineering parameters or to physical characteristics will have an impact on kLa and should be considered when evaluating bioreactor platforms and … See more Imagine a gas bubble in liquid. For this discussion the gas bubble contains oxygen, and the liquid is the liquid in a bioreactor. kLa can be represented by the following equation: kLa = kL × a 1. Where kLa is the mass … See more WebThe oxygen flow rate during blowing for a three tonne capacity furnace is 20–30 Nm 3 /h. ... The change to the lance-based furnace increased oxygen utilization to 95% and the cycle time was reduced to a little less than eight hours, “but the grade of the doré which could be economically produced was poor.” ...
