“…Further, it has been suggested that in microalgae species with moderate amounts of lipids could be possible to improve these amounts by modifying the culture conditions and nutrient availability. In that sense, it is well documented that under deficient nutrient conditions, neutral lipids synthesis is favored and can be used as an alternative source of biofuels; therefore, it is necessary to find the most suitable species and define the culture conditions that could help to achieve this purpose (Vuppaladadiyam et al, 2018;Zulu et al, 2018).…”

Chaetoceros muelleri is one of the most widely used microalgae species in aquaculture in northwestern Mexico as food for fish and crustaceans. Its importance is due to its fast growth, nutritional quality and lipid accumulation under nutrient-limiting conditions. However, the biochemical and molecular mechanisms of uptake of phosphorus (P) limiting conditions for this species is still unknown. This study aimed to analyze the growth and biochemical composition of C muelleri in response to different phosphorus concentrations. Four treatments under different phosphorus conditions were used: control (72 µM P), excess (144 µM P) and two treatments with phosphorus limitation, limited A (18 µM P) and limited B (7 µM P). The highest cell concentration was observed in control and excess of P (>3.4×10 6 cells mL -1 ). The highest dry mass concentration and chlorophyll-a content were found in control medium (72 µM P) whereas the highest total lipid (4.42%) was found in the lowest P-concentration medium (7 µM P). No significant differences were found in the total protein content, but we did find differences between the treatments with phosphorus limitation (7 and 18 µM P).

“…Table 1 shows different marine microalgae species that have the potential to produce multiple compounds. Marine microalgal carbohydrates are mainly present as cellulose in the cell wall and starch in the plastid [32]. Monosaccharides are the basic components of carbohydrates in microalgae, which consist of glucose, galactose, mannose, rhamnose, arabinose, xylose, ribose, and fucose [33].…”

Marine microalgae are regarded as potential feedstock because of their multiple valuable compounds, including lipids, pigments, carbohydrates, and proteins. Some of these compounds exhibit attractive bioactivities, such as carotenoids, ω-3 polyunsaturated fatty acids, polysaccharides, and peptides. However, the production cost of bioactive compounds is quite high, due to the low contents in marine microalgae. Comprehensive utilization of marine microalgae for multiple compounds production instead of the sole product can be an efficient way to increase the economic feasibility of bioactive compounds production and improve the production efficiency. This paper discusses the metabolic network of marine microalgal compounds, and indicates their interaction in biosynthesis pathways. Furthermore, potential applications of co-production of multiple compounds under various cultivation conditions by shifting metabolic flux are discussed, and cultivation strategies based on environmental and/or nutrient conditions are proposed to improve the co-production. Moreover, biorefinery techniques for the integral use of microalgal biomass are summarized. These techniques include the co-extraction of multiple bioactive compounds from marine microalgae by conventional methods, super/subcritical fluids, and ionic liquids, as well as direct utilization and biochemical or thermochemical conversion of microalgal residues. Overall, this review sheds light on the potential of the comprehensive utilization of marine microalgae for improving bioeconomy in practical industrial application.

“…Microalgae are cultivated either in open pond systems or in closed reactor systems. A photobioreactor is used in microalgae cultivation by implementing bubble columns, airlift, tubular, flat-plate and stirred tank reactors [40]. A more comprehensive description of microalgae cultivation methods can be found elsewhere [41].…”

Nowadays the world is facing vulnerability problems related to food, energy and water demands. The challenges in those subsystems are intertwined and thus require inter-discipline approaches to address them. Bioresources offer promising solutions of the dilemma. Microalgae biomass is expected to become a superfood and a favorable energy feedstock and assist in supplying clean water and treat wastewater. Efficient mass production of microalgae, both during upstream and downstream processes, is thus a key process for providing high quality and affordable microalgae biomass. This paper covers recent progress in microalgae harvesting and dewatering by using osmotic driven membrane process, i.e., forward osmosis. Critical factors during forward osmosis process for microalgae harvesting and dewatering are discussed. Finally, perspective on further research directions and implementation scenarios of the forward osmosis are also provided.
