“…The obtained fat content by using the acid hydrolysis is considerably improved (36.74% from dried egg without hydrolysis and 42.39% using acid hydrolysis before extraction) [18]. Teymouri et al [19] used hydrolysis before solvent extraction of lipids from algae. These minerals play an important role in human growth and development due to their contribution to nutrient metabolism, hormonal function and cell differentiation [20].…”

The objective of this study was to determine the chemical composition of five different food seeds (sunflower, poppy, hemp, flax and sesame) regarding fatty acid, mineral (Fe, Cu, Zn, Na, Mg, K, Ca, Al) and protein content. In addition, the total antioxidant capacity of the seeds was evaluated using the photochemiluminescent assay. The food seeds were subjected to lipid extraction and converted into fatty acid methyl esters before the gas chromatography analysis. In all food seeds, the saturated (SFAs), monounsaturated (MUFAs) and polyunsaturated fatty acids (PUFAs) were identified, respectively. PUFAs were the most abundant fatty acids (61.2% ± 0.07% and 84.8% ± 0.08% of total fatty acids), with the highest content in flax and hemp seed oil. Also, high amounts of omega-3 from PUFAs were determined in flax and hempseed oil. Based on the obtained results the sunflower, sesame and poppy seeds are good sources of omega-6, while flax and hemp seeds are good sources of omega-3. All samples are rich in minerals (Na, K, Ca, Mg) and have more than 20% protein content.

“…During HTL carbohydrate will generate hydroxymethylfurfural, acetic acid, etc., while protein will be degraded into amino acid, peptides and other derivatives. 23 Most of these water-soluble degradation products will end in the aqueous phase. 4 Since the carbohydrate and FAME contents for 1 st harvest and 3 rd harvest were similar (Table 1), the remarkable increase of bio-oil yield in 3 rd biomass is very likely due to the presence of mcl-PHA.…”

“…Second, it solubilizes carbohydrates and some proteins to produce a fermentable hydrolysate. Many technologies have been applied for algae cell lysis, though not always in a fuel production or whole biomass valorization context (Teymouri et al, 2018). Among those that have, acid pretreatment is among the most promising (Yu et al, 2015;Kruger et al, 2018).…”

Enabling Production of Algal Biofuels by Techno-Economic Optimization of Co-Product Suites

Recent techno-economic analysis (TEA) has underscored that for algal biofuels to be cost competitive with petroleum fuels, co-products are necessary to offset the cost of fuel production. The co-product suite must scale with fuel production while also maximizing value from the non-fuel precursor components. The co-product suite also depends on algal biomass composition, which is highly dynamic and depends on environmental conditions during cultivation. Intentional shifts in composition during cultivation are often associated with reduced biomass productivity, which can increase feedstock production costs for the algae-based biorefinery. The optimal algae-based biorefinery configuration is thus a function of many factors. We have found that comprehensive TEA, which requires the construction of process models with detailed mass and energy balances, along with a complete accounting of capital and operating expenditures for a commercial-scale production facility, provides invaluable insight into the viability of a proposed biorefinery configuration. This insight is reflected in improved viability for one biorefining approach that we have developed over the last 10 years, namely, the Combined Algal Processing (CAP) approach. This approach fractionates algal biomass into carbohydrate-, lipid-, and protein-rich fractions, and tailors upgrading chemistry to the composition of each fraction. In particular, transitioning from valorization of only the lipids to a co-product suite from multiple components of high-carbohydrate algal biomass can reduce the minimum fuel selling price (MFSP) from more than $8/gallon of gasoline equivalent (GGE) to $2.50/GGE. This paper summarizes that progress and discusses several surprising implications in this optimization approach.
