“…Microalgae are an extremely diverse group of microscopic, unicellular and photosynthetic microorganisms mostly found in marine and freshwater environments 15,16 . Microalgae includes eukaryotic cells such as Chlorophyceae (green algae), Bacillariophyceae (diatoms algae), Chrysophyceae (golden algae).…”

Utilising novel ingredients in aquafeeds is necessary for the continued expansion and intensification of aquaculture production. Microalgae are utilised widely in aquaculture for a variety of purposes; as live feed for fish and shellfish larvae and juveniles, for the production of algae‐based meals and oils to replace marine derived raw materials in aquafeeds, and for the production of astaxanthin, the carotenoid that gives salmon flesh its characteristic reddish colour. Notably, long‐chain polyunsaturated fatty acids, amino acids, proteins, fibres, antioxidant pigments, vitamins and minerals are among the compounds in microalgae with great biological value. A growing collection of experimental data has demonstrated that these substances are crucial for increasing larval survival and enhancing the growth and well‐being of fish and shellfish. In this review, the processing of microalgae utilised as aquafeed ingredient, the health promoting compounds in microalgae and their role in growth, immunity and disease resistance of fish and shellfish are described and discussed. Simultaneously, major hurdles in the commercial use of microalgae in aquafeed, and future research and development perspectives are all critically discussed.

“…Different treatment technologies have been studied such as adsorption, physicochemical treatment or coagulation; however, they must be coupled with others to achieve higher performance, implying high operating costs [5]. In this sense, the adsorption methods based on lignocellulosic products become important due to their sustainable nature and physicochemical characteristics [6]. Anionic surfactants removal studies, such as Linear Alkylbenzene Sulfonate (LAS), are focused on techniques of combining technologies, adsorption using activated carbons or by carbon nanotubes.…”

Water pollution is a concern globally extended due to the need of preserving human health and environment. In the search for solutions, residual biomass has been used for its decontamination due to easy implementation and low cost. In this research, a rapid-mixed biofilter was developed to process 0.75 mL/s of greywater contaminated with 93.04 ppm of Linear Alkylbenzene Sulfonate (LAS). The removal efficiency, optimal design and operating conditions were evaluated. Finally, the performance of the system was modeled by the BSDT and Clark breaking curves to determine the saturation time. Results showed a removal percentage of 91.27 %. In addition, it was observed that bed height has a positive effect on the adsorption due to the increase of active sites. The Clark model was the one that best fitted the data which confirms that at long residence times inside the column, the concentration at the exit will tend to be significantly reduced.

“…They are aquatic photosynthetic organisms that have higher growth rates than terrestrial plants and do not compete with food crops and agricultural lands due to its ability for growing in unsuitable conditions needing merely some nutrients and sunlight [3,4]. The interest for these organisms lies in their potential to produce biomass for food, feed and valuable chemicals but mainly for the possibility of synthetizing biofuels from microalgae biomass [5,6]. Generally, there are three main components in microalgae: carbohydrates, proteins, and lipids.…”

Recently, microalgal biomass has attached much attention due to the wide diversity of compounds synthesized from different metabolic pathways. This work attempts to study metabolites recovery from Nannochloropsis sp. biomass concentrated by centrifugation and flocculation. Carbohydrates were obtained using acid and alkaline hydrolysis required for cell disruption. Protein extraction was performed after alkaline pretreatment and lipids were recovery by acid hydrolysis-Soxhlet and alkaline hydrolysis-Soxhlet extraction routes. It was found that carbohydrates were recovered by acid hydrolysis in 41 % and 35.39 % for centrifuged and flocculated biomass, respectively, values higher than thus reported using alkaline hydrolysis. For protein extraction, centrifuged biomass exhibited higher recovery yield (55.48%) than flocculated biomass (38.40%). The lipid extraction route that achieved highest yield (43.45%) was acid hydrolysis with HCl followed by Soxhlet extraction with hexane. In addition, statistical analysis by T test suggested that flocculants affect negatively biomass culture, hence, efficiency of metabolites extraction.
