Microalgal studies for the 21st Century

Microalgal photosynthesis is efficient enough to fix CO₂ in both atmosphere and industrially discharged gases, and is a possible future alternative for CO₂ reduction. This paper describes physiological responses of microalgal cells to extremely high CO₂ concentrations, capability of microalgal cells to fix CO₂ at both indoor and outdoor culture experiments, and efforts to establish a culture collection of marine microalgae. Recent researches indicate that microalgae are likely to play a key role in worldwide issues of the coming century.
