As mammals are unable to synthesize essential polyunsaturated fatty acids (PUFA), these compounds need be taken in through diet. Nowadays, obtaining PUFA diet is becoming increasingly difficult; therefore this work investigated the suitability of using macroalgae as novel dietary sources PUFA. Hence, 17 macroalgal species from three different phyla (Chlorophyta, Phaeophyta and Rhodophyta) were analyzed their acid methyl esters (FAME) profile was assessed. Each phylum presented a...
The objective of this techno-economic analysis is to define the costs for an industrial microalgae production process, comparing different operation strategies (Nannochloropsis oceanica cultivation during whole year or two species, where Phaeodactylum tricornutum and Tisochrysis lutea alternate), scales (1 10 ha), harvesting technologies (centrifugation ultrafiltration) drying methods (freeze-drying spray drying). This study based on scale process established in south Portugal. strategy...
We describe a new selection method based on BODIPY (4,4-difluoro-1,3,5,7-tetramethyl-4-bora-3a,4a-diaza-s-indacene) staining, fluorescence activated cell sorting (FACS) and microplate-based isolation of lipid-rich microalgae from an environmental sample. Our results show that direct onto solid medium upon FACS can save about 3 weeks during the scale-up process as compared with growth same cultures in liquid medium. This approach enabled us to isolate biodiverse collection several axenic...
Abstract Industrial scale-up of microalgal cultures is often a protracted step prone to culture collapse and the occurrence unwanted contaminants. To solve this problem, two-stage process was developed – heterotrophically Chlorella vulgaris cells grown in fermenters (1 st stage) were used directly inoculate an outdoor industrial autotrophic production unit (2 nd stage). A preliminary pilot-scale trial revealed that C. adapted readily growth conditions (1-m 3 photobioreactors) without any...
Microalgae are widely used as food supplements due to their high protein content, essential fatty acids and amino well carotenoids. The addition of microalgal biomass products (e.g., baked confectioneries) is a common strategy attract novel consumers. However, organoleptic factors such color, taste smell can be decisive for the acceptability foods supplemented with microalgae. aim this work was develop chlorophyll-deficient mutants Chlorella vulgaris by chemically induced random mutagenesis...
The nutritional requirements of novel microalgal strains are key for their effective cultivation and metabolite content. Therefore, the optimization heterotrophic photoautotrophic culture media is crucial Chlorococcum amblystomatis growth. Heterotrophic biomass samples were characterized to identify differences between composition biotechnological potential. Media through surface response methodology led 44.9 51.2% increments in C. amblystomatis-specific growth rates under growth,...
Abstract Industrial production of novel microalgal isolates is key to improving the current portfolio available strains that are able grow in large-scale systems for different biotechnological applications, including carbon mitigation. In this context, Tetraselmis sp. CTP4 was successfully scaled up from an agar plate 35- and 100-m 3 industrial scale tubular photobioreactors (PBR). Growth performed semi-continuously 60 days autumn-winter season (17 th October – 14 December). Optimisation PBR...
Commercial production of microalgal biomass for food and feed is a recent worldwide trend. Although it common to publish nutritional data microalgae grown at the lab-scale, about industrial strains cultivated in an setting are scarce literature. Thus, here we present composition microbiological toxicological evaluation Tetraselmis sp. CTP4 biomass, 100-m3 photobioreactors facility (AlgaFarm). This microalga contained high amounts protein (31.2 g/100 g), dietary fibres (24.6 digestible...
Abstract Bioprospecting for novel microalgal strains is key to improving the feasibility of microalgae-derived biodiesel production. Tetraselmis sp. CTP4 (Chlorophyta, Chlorodendrophyceae) was isolated using fluorescence activated cell sorting (FACS) in order screen lipid-rich microalgae. a robust, euryhaline strain able grow seawater growth medium as well non-sterile urban wastewater. Because its large size (9–22 μm), settles down after six-hour sedimentation step. This leads removal...
As the periodic emission of light pulses by emitting diodes (LEDs) is known to stimulate growth or induce high value biocompounds in microalgae, this flashing regime was tested on and biochemical composition microalgae Nannochloropsis gaditana, Koliella antarctica Tetraselmis chui. At low frequencies (e.g., 5 50 Hz, Duty cycle = 0.05), a strain-dependent inhibition an accumulation protein, polyunsaturated fatty acids, chlorophyll carotenoids (lutein, β-carotene, violaxanthin neoxanthin)...
Microalgae are considered a promising resource of proteins, lipids, carbohydrates, and other functional biomolecules for food feed markets. Competitive drying solutions required to meet future demands high-quality algal biomass while ensuring proper preservation at reduced costs. Since often used methods, such as freeze or spray drying, energy time consuming, more sustainable processes remain be developed. This study tested an indirect hybrid solar dryer alternative conventional industrially...
