Design and performance of a photobioreactor for microalgae production

Published on 19 June 2025 at 18:43

In today's article, I'll talk about a research paper I discovered to learn more about photobioreactors, which is required for my internship. Reading the article The design and performance of a low-cost, automated, large-scale photobioreactor for microalgae production will help me prepare for my internship at Comfac Systems Corp., who is developing a photobioreactor for their factory. The paper discusses the use of Tetraselmis chuii as the algae for the photobioreactor.

Here are some notes that I have taken:

  • Tetraselmis chuii is a preferred microalga in oyster hatcheries due to its optimal nutrient profile.
  • Light intensity was the primary limiting factor in algal growth.

  • Optical density via photoresistors was effective for monitoring but diverged at late growth stages.

  • CO₂ and pH fluctuations did not significantly impact growth.

  • Ideal for aquaculture hatcheries due to reduced labor, higher density, and automation.

 

Thank you for tuning in for this post; come back next month for more!
