Abstract

Microalgae have recently attracted considerable interest worldwide, due to their extensive application potential in the renewable energy, biopharmaceutical, and nutraceutical industries. Microalgae are renewable, sustainable, and economical sources of biofuels, bioactive medicinal products, and food ingredients. For microalgal production, the choice of the photobioreactor, the method of cultivation used, and the harvesting regime adopted (batch, semi-continuous and continuous cultures) are very important. In this work, we examined the growth rate and productivity of a small volume (2 L) experimental culture in batch and semi-continuous mode. Several microalgae species have been investigated for their potential as value-added products, thus we have chosen two species: green microalga (Nannochloropsis gaditana) and a cyanobacterium (Arthrospira platensis). This study develops a simple model by which biomass values in semi-continuous operations can be predicted from kinetic growth parameters obtained from a batch experiment. Based on results, biomass concentrations and productivity in continuous operation can be successfully predicted.
