“…These compounds include the primary metabolites needed for reproduction like proteins, lipids and carbohydrates, and secondary metabolites, which have diverse functions and chemical structures like flavonoids, terpenoids, and alkaloids. The rapid growth of some microalgae offers opportunities to continuously produce lipid-, starch-or protein-rich biomass, for example for aquaculture (Atalah et al, 2007;Ganuza et al, 2008;Hemaiswarya et al, 2011;Hussein et al, 2013;Velasquez et al, 2016).…”

AbstractMicroalgae have been studied as biofactories for almost four decades. Yet, even until today, many aspects of microalgae farming and processing are still considered exploratory because of the uniqueness of each microalgal species. Thus, it is important to develop the entire process of microalgae farming: from culturing to harvesting, and down to extracting the desired high-value products. Based on its rapid growth and high oil productivities, Nannochloropsis sp. is of particular interest to many industries for the production of highvalue oil containing omega-3 fatty acids, specifically eicosapentaenoic acid (EPA), but also several other products. This review compares the various techniques for induction, harvesting, and extraction of EPA-rich oil and high-value protein explored by academia and industry to develop a multi-product Nannochloropsis biorefinery. Knowledge gaps and opportunities are discussed for culturing and inducing fatty acid biosynthesis, biomass harvesting, and extracting EPA-rich oil and high-value protein from the biomass of Nannochloropsis sp.

“…Moreover, microalgae like Nannochloropsis, Tetraselmis, Dunaliella, and Chlorella, are deficient in DHA, and feeding them to B. plicatilis results in DHA/EPA ratios lower than 0.5. HUPArich microalgae such as Isochrysis and Pavlova contain high DHA levels and can be fed to B. plicatilis for DHA enrichment, which results in DHA/EPA ratios above 2.0 (Hemaiswarya et al, 2011). However, the nutritional value of baker's yeast (as not laborious, not time consuming and not expensive diet for rotifer) may be enhance easily by adding of marine oil enrichment, especially EPA and DHA that are needed for all marine larvae (Ferreira, et al, 2009).…”

“…Apart from pure algae, there is a number of yeast or algae-based rations suitable for culturing rotifers that are commercially available (Chew and Lim, 2006). Rotifers are fed on different microalgal species, such as Nannochloropsis, Chaetoceros, Tetraselmis, Dunaliella (Abdel Rahman et al, 2008), Spirulina, Chlorella (Jabeur et al, 2013 ) and Pavlova (Hemaiswarya et al, 2011), as live, frozen, or dried microalgae. The high cost of microalgae may limit rotifer production and success in marine hatcheries.…”

Rotifers Brachionus plicatilis are the most common zooplankton used to rear eairly larvae of marine shrimp and finfish. Reduce production cost of live food in marine hatcheries is considered one of the main targets for developing a marine aquaculture industry. The present study is conducted to investigate the population (as increase in number) and population growth rate of rotifer Brachionus plicatilis fed on un-live microalgal diet, frozen Nannochloropsis oculata (FN) and dried Spirulina platensis (DS), comparing to dried baker's yeast Saccharomyces cerevisiae (Y) in four treatment; alone for each diet and mixing between S. platensis + yeast and yeast: (FN, DS, DS+Y, and Y). The experiment was continued for 12 day in batch culture system with initial rotifer population 100/ind./ml. The lowest average in population and population growth rate were observed in rotifer fed on SD (122.90±43.38 Ind./ml and 0.137 ind./day, respectively), while the highest R FN and R r were observed in Y (182.24±43.89 ind./ml and 0.569 ind./day), followed by DS + Y (166.00 ± 32.58 Ind./ml and 0.486 ind./day) and FN (130.09 ± 21.51 ind./ml and 0.251 ind./day, respectively). In general, Baker's yeast is cheap and readily available; in contrast, microalgae (fresh, freezed and dried) are laborious, time consuming and expensive. Baker's yeast S. cerevisiae has also been successfully used for rotifers with high population and population growth rate.

ABSTRACT. The growth rate, fatty acid profile and toxicity of 21 microalgae strains (Cyanophyceae (3), Chlorodendrophyceae (1), Xanthophyceae (1) and Bacillariophyceae (16)), isolated from coastal waters of Baja California (NW México), were determined. Cyanophytes Komvophoron sp. had the highest growth rates (μ = 2.98 divisions day ). Fatty acid content differed according to taxonomic group. Diatoms contained the highest percentages of polyunsaturated fatty acids (n-3 and n-6 PUFAs), ranging from 23.4 to 60.7%, and eicosapentaenoic acid (EPA) was the most abundant. None of the residual media from the isolated microalgae strains were toxic to Artemia franciscana nauplii. We conclude that based on their growth rate, fatty acid profile, and lack of toxicity, all the isolated microalgae strains have the potential to be used alone or as part of a mixed diet for the culture of marine organisms.
