“…Interestingly, this work is the first study that evaluates A. platensis free lipid (FL) as feed for marine rotifer B. plicatilis. Our results are in the same line with the many studies that evaluated the effect of microalgal-free lipid as feed for Artemia [17,86,87] and concluded that microalgae-biodiesel byproduct (FL) significantly improved survival and growth of Artemia franciscana. Ashour et al [17] reported that applying 0.1 g L −1 of FL of N. oceanica NIOF15/001 significantly improved survival (500%) and growth (40%) of A. franciscana.…”

To achieve strong, successful and commercial aqua-biotechnological microalgae applications, screening, isolation, molecular identification, and physiological characterizations are needed. In the current study, a native cyanobacteria strain Arthrospira platensis NIOF17/003 was isolated from the surface water of El-Khadra Lake, a saline-alkaline lake located in Wadi El-Natrun, Egypt. The cyanobacterium was phylogenetically identified by 16S rRNA molecular marker and deposited in the GenBank database (accession number MW396472). The late exponential phase of A. platensis NIOF17/003 was reached at the 8th day of growth using Zarrouk medium, with a recorded dry weight (DW) of 0.845 g L−1. The isolated strain showed 52% of protein, 14% of carbohydrate, biomass productivity of 143.83 mg L−1 day−1, 8.5% of lipid, and lipid productivity of 14.37 mg L−1 day−1. In general, the values of cetane number, iodine value, cold filter plugging point (52.9, 85.5 g I2/100 g oil, and −2.2 °C, respectively) of the isolated fatty acid methyl esters are in accordance with those suggested by international standards. Besides, applying algal-free lipid (FL) as biodiesel byproduct in the production of rotifer (Brachionus plicatilis) revealed that a 0.6 g L−1 FL significantly increased the rotifer population females carrying eggs, confirming that FL can be used efficiently for B. plicatilis production. The current study concluded that the new isolate A. platensis NIOF17/003 is a promising strain for double sustainable use in biodiesel production and aquaculture feed.

“…Abomohra et al [86] concluded that FL of S. obliquus up to 0.2 g L −1 improves the survival of Artemia up to 50%. Moreover, El-Kassas et al [87] confirmed that a mixed diet of lipid-free algal biomass (0.5 g L −1 ) achieved the highest survival (91.8%) and the highest average of fresh weight (4.2 mg) of Artemia up to about 50%.…”

“…Monitoring of the algae growth was determined during the exponential phase that mainly relied upon the inocula sizes, culture conditions and the constituents of the growth media (Jayasankar and Valsala, 2008;El-kassas et al, 2016). Growth evaluation, represented by biomass and algal biochemical analysis are two essential attributes to evaluate the prospective of a species as promising candidates for different applications (Arauĵo and Garcia, 2005;El-kassas et al, 2016) for Chorella spp. and their application in aquaculture feeding for N.oceanica (Ashour et al, 2019).…”

“…Recently, aquaculture technologies were developed rapidly to meet human demand as supplementation with dietary lipids or proteins (Ashour et al, 2019). They investigated also application of lipid-free algal biomass in enhancing Artemia development and survival for improving aquaculture (El-Kassas et al, 2016). However, Heflin et al (2012) concluded that protein content is the most important components in aquaculture feeds.…”

This work was carried out, firstly for investigating the different effects of various organic carbon sources [fructose (A), lactose (B), glucose (C)], and nitrogen sources [poultry manure extract (PM) and rumen liquor (RL)] which used at ratio 50:50% F/2 medium on maximizing production of biodiesel from the marine microalga Nannochloropsis oceanica. Secondly, we apply the residual lipid-free biomass as feed additives in Red tilapia aquaculture. In phase1, the biomass (DW), biodiesel contents and biochemical compositions of N. oceanica were determined. The results showed varied biomass and biochemical analysis in DW bases between treatments. However, A was achieved significantly the maximum DW for the algal biomass and protein percentage, whereas lipid accumulation was the most in RL as well as achieving the highest biodiesel content. In phase 2, algal biomass by-product (lipid-free) from the superior treatments A and RL were applied at 4 rates (1,2,3 and 4) for concentrations 25,50,75&100%, respectively that substituting soybean for feeding red tilapia larvae as compared with control CO. The initial weight and length of the larvae were 0.32g and 1.9 cm, respectively continued for a duration of 30 days of the experiment. After the end of the experimental period , growth performance, survival percentage (SR%) and biochemical analysis were estimated. The results revealed that SR% was higher significantly for RL2 than A1 (93% & 90%) as compared to control (86.7%). Accordingly, red tilapia carcass attained maximum protein contents for diets A1 & RL2 in whereas lipid content was maximum in control. Finally, authors suggesting the use of Roman liquor as a novel treatment for cost-effective promoting biodiesel content and the remained biomass with 50% substitution of soybean in the diet (RL2)achieved also good results for improving red tilapia aquaculture.
