Executive Industry Relevance

This protocol enables safe and reproducible cultivation of microalgae using corrosive flue gases, supporting early-stage target validation in environmental biotechnology and biofuel development. By integrating toxic gas monitoring, fume hood safety protocols, and biomass quantification via OD750 calibration, the method provides a controlled system for assessing photosynthetic productivity under industrial emission conditions. This approach de-risks downstream applications by establishing reliable growth metrics and safety benchmarks before scale-up.
