Abstract Mixotrophic cultivation of Haematococcus lacustris is one the most promising strategies to produce natural astaxanthin. During mixotrophic growth, microalgae assimilate and metabolize organic carbon in addition photosynthetic resulting increased biomass productivity.

Carbon and nitrogen present in residual water streams can be converted into microbial protein used as animal feed aquaculture. While is thought to more environmentally sustainable when compared proteins made from fish residues or plants, nothing known about how it performs an absolute sustainability perspective, relative planetary boundaries. Here, a systems-oriented analysis using life cycle assessment (LCA) linked the boundaries framework was conducted assess environmental performance of pilot-scale production starch-rich process aerobic heterotrophs. Results showed that while this microbial-protein indeed performed significantly better than just fishmeal soybean meal for impacts related (N) phosphorus (P) flows, none three feeds were found relation all This constitutes opportunity technology developers scaled up matures.

The sustainability of recycling aquaculture systems (RAS) is challenged by nutrient discharges, which cause water eutrophication. Efficient treatments for RAS effluents are needed to mitigate its environmental impacts. Microalgae assimilate nutrients and dissolved carbon into microbial biomass with value as feed or food ingredient. However, they difficult harvest efficiently. Daphnia magna an efficient filter feeder that grazes on microalgae at high rates serves valuable fish feed. Combining removal harvesting D. could be a cost-effective solution wastewater valorization. Nutrient from unsterilized was evaluated using the species Chlorella vulgaris, Scenedesmus dimorphus, Haematococcus pluvialis. first two algae were subsequently harvested grazer, while H. pluvialis failed grow stably. All phosphorus removed, only 50–70 % nitrogen recovered, indicating limitation. Shortening hydraulic retention time (HRT) dosing resulted in increased removal. C. vulgaris cultivation unstable 3 days HRT when supplied extra 5 HRT. grew produced accumulating protein 20–30 dry weight, amino acid profile favorable use Thus, this study demonstrates application steps multitrophic process residual live feeds suitable fish.

Undernutrition is an important global health problem, especially in children and older adults. Both reversal of maternal child undernutrition heathy ageing have become United Nations-supported initiatives, leading to increased attention nutritional interventions targeting undernutrition. One feasible option microalgae, the precursor all terrestrial plants. Most commercially farmed microalgae are photosynthetic single-celled organisms producing organic carbon compounds oxygen. This review will discuss commercial opportunities grow microalgae. Microalgae produce lipids (including omega-3 fatty acids), proteins, carbohydrates, pigments micronutrients so can provide a suitable underutilised alternative for addressing The benefits nutrients derived from been identified, thus they candidates issues globally. potential microalgae-derived be converted into food products. advantages cultivation include that it does not need arable land or pesticides. Additionally, most species still unexplored, presenting options further development.

Incorporating a variety of microalgae into wastewater treatment is considered an economically viable and environmentally sound strategy. The present work assessed the growth characteristics Chlorella sorokiniana during cultivation in balanced synthetic media domestic wastewater. Increasing NH4+-N concentration to 360 mg L-1 adding extra PO43--P SO42--S (up 80 36 L-1, respectively) contributed increase total biomass levels (5.7-5.9 g L-1) C. media. Under these conditions, maximum concentrations chlorophylls carotenoids were 180 ± 7.5 26 1.4 respectively. Furthermore, when studying three types wastewaters, it was noted that only one productive sorokiniana, but all wastewaters stimulated increased accumulation protein. Finally, alga, growing optimal unsterilized wastewater, showed specific rate 0.73 day-1, productivity 0.21 100% removal. These results demonstrate tested alga actively adapts changes composition medium accumulates high protein systems with poor-quality water.
