“…EAA indices for algal biomass are rarely found in the published literature and have not been reported for most of the species studied here (with exception of Chlorella). The range we observed (0.86-1.10) agrees well with Brown and Jeffrey [69] and Tibbetts et al [70,71] who also reported moderate to high protein quality of other algal species (0.80-1.25). While EAA indices of biomass from C. vulgaris (0.92-0.93), M. reisseri (0.90-0.92) and N. bacillaris (0.86-1.07) were similar or exceeded that of soybean protein (0.9), Tetracystis sp.…”

“…If the proteins can be extracted and purified, the resulting product can be sold at a higher price especially with the complete set of essential amino acids contained in the proteins (Kent et al, 2015;Tibbetts et al, 2015). Aside from this, Samarakoon et al (2013) discovered that N. oculata contains ACE inhibitory peptides, which has important functions in the prevention of hypertension.…”

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.

“…Mild heating of native proteins causes disruption of secondary and tertiary structures, which allows proteins to unfold, permitting for more efficient enzymatic digestion. Although the amino acid profiles of microalgal proteins are generally high relative to other common plant proteins [9,14,31], the functional properties of algal proteins are poorly understood. Chronakis [27] demonstrated that Spirulina proteins are highly viscous at acidic pH but become less viscous and more highly soluble at higher pH levels and this could affect the results from the various in vitro protein digestion assays used.…”

For WAB, protein solubility (PS) was statistically highest and the same (P = 0.109) for Chlorella vulgaris at 84% and Micractinium reisseri at 78%, lowest (P b 0.001) for Nannochloris bacillaris at 64% and intermediate for Tetracystis sp. at 73%. Dilute pepsin digestibility (DPD) was highest (P b 0.001) for C. vulgaris at 80% and lowest (P b 0.001) for N. bacillaris and Tetracystis sp. at 60-64%, which were the same (P = 0.075) and M. reisseri was intermediate at 72%. Twophase gastric/pancreatic digestibility of protein (GPD Protein ) and energy (GPD Energy ) were highest (P b 0.001) for M. reisseri at 78 and 57%, respectively, lowest (P b 0.001) for N. bacillaris and Tetracystis sp. at 49-52 and 41-43%, respectively, which were the same (P = 0.101 and 0.058, respectively) and C. vulgaris was intermediate at 69 and 52%, respectively. For LEB, PS was highest (P b 0.001) and the same (P = 0.088) for C. vulgaris and M. reisseri at 72-76%; which were higher (P b 0.001) than N. bacillaris and Tetracystis sp. at 60-62%, which were the same (P = 0.405). Similarly, DPD was highest (P b 0.001) and the same (P = 1.000) for C. vulgaris and M. reisseri both at 69%; which were higher (P b 0.001) than N. bacillaris and Tetracystis sp. at 58-62%, which were the same (P = 0.083). GPD Protein was highest (P b 0.001) and the same (P = 0.944) for M. reisseri and C. vulgaris at 79-80%, lowest (P b 0.001) for N. bacillaris at 50% and intermediate for Tet...
