“…Microalgae biomass concentration was determined simultaneously by dry weight (DW) measurement and by total organic carbon (TOC) concentration in culture samples [32]. For DW measures, aliquots of the culture suspensions were filtered through pre-weighted glass microfiber filters (Whatman, 0.45 µm pore diameter).…”

“…For example, when the light path in an open pond increases from 0.10 to 0.30 m, the maximum biomass density of cyanobacterium Anabaena sp. is found to decrease from 0.55 g L −1 to 0.35 g L −1 (Clares et al, ; Moreno, ). The maximum biomass density of green alga Chlorella ellipsoidea is only found to be 0.53 g L −1 in a 200 L tubular PBR with a large diameter of 0.48 m (Wang et al, ).…”

This paper investigates the scaling‐up of cyanobacterial biomass cultivation and biohydrogen production from laboratory to industrial scale. Two main aspects are investigated and presented, which to the best of our knowledge have never been addressed, namely the construction of an accurate dynamic model to simulate cyanobacterial photo‐heterotrophic growth and biohydrogen production and the prediction of the maximum biomass and hydrogen production in different scales of photobioreactors. To achieve the current goals, experimental data obtained from a laboratory experimental setup are fitted by a dynamic model. Based on the current model, two key original findings are made in this work. First, it is found that selecting low‐chlorophyll mutants is an efficient way to increase both biomass concentration and hydrogen production particularly in a large scale photobioreactor. Second, the current work proposes that the width of industrial scale photobioreactors should not exceed 0.20 m for biomass cultivation and 0.05 m for biohydrogen production, as severe light attenuation can be induced in the reactor beyond this threshold.

“…Regarding temperature, most microalgae grow well in the range of 20-30 °C. Over this value, only some extremophile strains show acceptable growth, including some Scenedesmus strains and some cyanobacteria as Anabaena [19,20]. Below the optimal temperature, the growth is reduced, but over the critical one, the culture dies; by this reason to avoid overheating of the cultures is mandatory in whatever microalgae production system.…”

“…Regarding the pH, it can be controlled by providing acidic solutions to the culture medium, but usually the injection of CO 2 is used to reduce the pH and avoid carbon limitation at the same time. The optimal pH for most of the microalgae strains ranges from 7 to 8, although some cyanobacteria show optimal performance at pH up to 10 [19]. To provide CO 2 for pH control is an engineering problem that must be adequately optimized to minimize the amount of CO 2 consumed while increasing the biomass productivity of the system, always considering the cost of infrastructure and energy consumption involved [13].…”

Case Study of Innovative Projects - Successful Real Cases

Microalgae were the basis of life into the planet, but only recently these microorganisms are exploited at a commercial scale. Thus, the production of pharmaceuticals, cosmetics, feed, and foods from microalgae is today a commercial reality increasing year by year. Additionally, microalgae have been proposed to be used to enhance the sustainability of existing industrial activities, as wastewater treatment and biofuel production. In this way, the utilization of microalgae at a large scale is considered a green revolution in the sustainability of mankind. This chapter is focused on reviewing the real contribution of microalgae to human activities. The last improvements of technologies and its uses, in addition to still existing bottlenecks for the massive exploitation of these microorganisms, are reviewed.
