Table 1 Comparison of cost and efficiency of open ponds and bioreactors for microalgae cultivation

From: Allelopathy as a potential strategy to improve microalgae cultivation

Factors Open ponds Bioreactors
Equipment Low cost High cost
Investment Low High
Operating Costs Low High
Maintenance and control of temperature No cost but difficult Easy but costly
Scaling up Easy Difficult
Agitation of large volumes of algae Difficult, low uniformity, and low cost Easy, high uniformity, and high cost
Evaporation of culture medium High Low
Risk of contamination High Reduced
Control of contamination Difficult Easy
Control of species Difficult Easy
Microalgae stress Low High
Maintenance and cleaning of the system Easy Difficult
Productivity Low High
