Bioreactor Controls-II01:18

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...

Area of Science:

  • Analytical Chemistry
  • Environmental Science
  • Laboratory Equipment Design

Background:

  • Nitrogen blowdown evaporation (NBE) is crucial for solvent removal in analytical methods.
  • Commercial NBE equipment is expensive, posing a barrier for research and early-stage analysis.
  • A need exists for affordable and reliable NBE solutions in laboratory settings.

Purpose of the Study:

  • To design and construct a low-cost, homebuilt nitrogen blowdown evaporator.
  • To validate the performance and reliability of the custom-built NBE apparatus.
  • To provide a practical and economical alternative to commercial NBE systems.

Main Methods:

  • Detailed design and construction using conventional, low-cost materials.
  • Proof-of-function experiment involving the evaporation of per- and polyfluoroalkyl substances (PFAS).
  • Material selection focused on avoiding background contamination.

Main Results:

  • The homebuilt NBE apparatus was constructed at approximately 20% of the cost of commercial units.
  • The apparatus demonstrated no detectable background contamination due to careful material selection.
  • High analyte recovery rates (99-100%) and favorable evaporation times were achieved.

Conclusions:

  • A functional and affordable nitrogen blowdown evaporator can be successfully built using readily available materials.
  • The homebuilt NBE is suitable for sensitive analytical applications, including PFAS analysis, with minimal analyte loss.
  • This cost-effective solution enhances accessibility to essential sample preparation techniques for researchers.
