Bioreactor Controls-I01:28

Bioreactor Controls-I

Maintaining optimal conditions within fermenters is essential for maximizing microbial productivity and ensuring process efficiency. This lesson focuses on key parameters—temperature, foam, pH, carbon dioxide, oxygen, and pressure—and their precise measurement and control strategies in fermentation systems.Temperature ControlTemperature regulation is critical due to the exothermic nature of many fermentation processes. In small laboratory fermenters, temperature is commonly monitored using...

Bioreactor Controls-II

In aerobic fermentations, oxygen is vital for microbial growth and metabolite production. Since air comprises only about 20% oxygen and the gas is poorly soluble in water—just 9 ppm at 20°C—supplying sufficient oxygen becomes a critical challenge, especially in high-demand processes like yeast growth or citric acid production. Even a fully saturated broth may offer only a few seconds of oxygen availability.To address this, sterile or scrubbed air is introduced into the fermentor via a sparger...

  • Utilized in vitro motility assays (IVMAs) to measure actin filament sliding velocity.
  • Evaluated surface hydrophobicity, roughness, and patterned microchannels.

Main Results:

  • FOTCS-functionalized surfaces via chemical vapor deposition showed highest average sliding velocity (3.9 ± 1.2 μm/s) and high motility (87%).
  • Vapor phase deposition offers a cost-effective method for tailoring surfaces.
  • Successfully patterned microchannels to confine motor-driven actin filament motion.

Conclusions:

  • Vapor phase deposition is a promising technique for surface modification in myosin-based nanotechnology.
