“…Although NEIST BT-2 yielded a high biomass, only a moderate amount of total lipid, i.e., 19.17% of dry cell weight was accumulated by it. Low lipid content of 4.65% and 19.47% w/w in Chlorella sorokiniana was also reported by Sinha et al (2016) and Eladel et al (2018), respectively. The highest amount of total, as well as neutral lipid (31.56% and, 260.29 a.u., respectively), was accumulated by NEIST BT-A6.…”

In the present study, seven axenic fresh water microchlorophytes were isolated and identified as Tetradesmus dimorphus (NEIST BT-1), Chlorella sorokiniana (NEIST BT-2), Desmodesmus sp. (NEIST BT-10), Selenastrum sp. (NEIST BT-A6), Tetradesmus obliquus (NEIST BT-A1), Tetradesmus sp. (NEIST BT-A10), and Asterarcys sp. (NEIST BT-A15) based on morphological and molecular characterization. Their potential to be used as biodiesel feedstock was evaluated depending on their growth characteristics and lipid profiles. Among the seven isolates, NEIST BT-2 was found to be the most promising candidate owing to its high biomass yield (2.09 ± 0.037 g L −1) and lipid productivity (107.60 ± 10.175 mg L −1 day −1). The gas chromatography analysis confirmed the presence of significant amounts of palmitic acid, linoleic acid, linolenic acid, and oleic acid in the isolate which are some of the major constituents of any biodiesel. The predictive models showed that the biodiesel from this isolate has ideal fuel properties which comply with the ASTM D6751 and EN 14214 specifications. These findings demonstrate that NEIST BT-2 can be used as a prospective candidate for consideration of large-scale biodiesel production.

“…In the current study, ammonium, nitrate and phosphate concentrations in unsterilized and undiluted wastewater were reduced by 100, 96 and 69%, respectively, after 22 days of C. sorokiniana growth. Previous studies on C. sorokiniana show similar results, with nutrient removal efficiencies of 74-84% after 10 days of growth in municipal wastewater (Eladel et al, 2019), and 92-97% removal after 24 days of growth in 50% diluted swine wastewater (Chen et al, 2020). In addition, this approach adds value to the water treatment process by the production of commercially valuable microalgal feedstock.…”

To meet the increasing demands of the growing population and to cope with the challenges of global change, both the production of biological feedstock and the recovery of recyclable natural resources play a critical role. Microalgal biomass is a promising source of renewable multifunctional feedstock, but the production is costly and requires large amounts of water. Here, we explored the potential of using wastewater as culture medium to lower the economic and environmental costs of microalgae biomass production and evaluated its valorization opportunities for animal feed production. As a proof of principle, we show that Chlorella sorokiniana can be cultivated on poultry wastewater, with a 83 and 113% increase in productivity when wastewater was first 50% diluted with tap water or standard growth medium, respectively. Wastewater sterilization before use enhanced algal growth with 36–118%, but only when wastewater was 25–50% diluted with standard medium. In contrast, it offered no additional benefits when dilutions were made with tap water or when wastewater was not diluted. At the end of the 22-days experiment, a maximum biomass of 0.8–1.9 g L−1 was reached for algae grown on wastewater. The produced biomass had a high macronutrient content, and the heavy metal content was below maximum limits for use in animal feed. Likewise, the tested pathogen groups were reduced until below safety norms for feed production after algal growth in unsterilized 50% wastewater (diluted with tap water). Overall, these findings add to our growing knowledge on the cultivation of microalgae on wastewater and its valorization opportunities, paving the way for a more sustainable use and reuse of resources.

“…Several studies were conducted in the fields of isolated of native microalgal species even from Mediterranean Sea (Abdel Rahman et al, 2010;Ashour et al, 2019), lakes (Aly and Gad, 2010;Selim et al, 2014;Marrez et al, 2014Abomohra et al, 2017Abdel-Razek et al, 2019), freshwater habitats (Mahmoud et al, 2015;Mohamed et al, 2017;, wastewater (Rakaiby et al, 2012;Mahmoud et al, 2016;Eladel et al, 2019;) or soil (El-Sheekh et al, 2017;2018). Moreover, several ecological studies were conducted to screening and identify the communities of microalgal species reported in Egyptian different water bodies like Mediterranean Sea (Fatma et al, 1995;Khairy et al, 2015), Red Sea and lakes (Ali and Khiray, 2012;Khiray et al, 2015).…”

Aquaculture is a global industry that supplies essential food to a growing world population and contributes more than 77% of the total Egyptian national fish production. Despite Egypt has a great potential in marine aquaculture, more than 95% of Egyptian aquaculture production is categorized as fresh water aquaculture. Until now, Egypt has no real marine aquaculture and this is attributed to many obstacles. One of these obstacles is the quality and quantity of microalgae in the marine hatcheries. Another obstacle is offering of the adequate aquaculture diet, quality and quantity. In this review, we concern on these two obstacles in relation to the current status and the future perspectives of microalgae as aquaculture feedstock in Egypt. In last few years, microalgae industry is one of the most growing industries over the world and can enhance the Egyptian national income, attributed to the great potential of microalgae production in Egypt, especially with the strong presence of microalgae production strategy keys like diversity of microalgae species in water bodies and land, culture conditions, culture facilities, native isolated strains, scientific and governmental interest, which provides great opportunities for success. The project funded from Academy of Scientific Research and Technology (ASRT) in title (Prototype of Sustainable Marine Integrated Aquaculture Farm for the Production of Seafood, Valuable Bio-Products and Biodiesel, SMIAF-Prototype), therefore, the project SMIAF aims to prepare an ideal prototype for marine sustainable integrated aquaculture farm that completely environmentally-friendly, produce sustainable seafood and highly effective for nutrients removal from aquaculture wastewater and convert these wastes by microalgae, as well as seaweeds, to valuable bio-products at semi-industrial scale, with high economic value.
