Abstract Maximal productivity of a 14 mm light‐path panel photobioreactor under high irradiance was determined. Under continuous illumination 2,100 µmol photons m −2 s −1 with red light emitting diodes (LEDs) the effect dilution rate on studied. The intensity used in this work is similar to maximal horizontal surface at latitudes lower than 37°. Chlorella sorokiniana , fast‐growing green microalga, as reference strain study. varied from 0.06 0.26 h . reached 0.24 value 7.7 g dw (m 2...
ABSTRACT Microalgae biofilms could be used as a production platform for microalgae biomass. In this study, photobioreactor design based on rotating biological contactor (RBC) was biomass cultivated in biofilm. the photobioreactor, referred to Algadisk, grow biofilm vertical disks partially submerged growth medium. The objective is evaluate potential of Algadisk with respect effects disk roughness, rotation speed and CO 2 concentration. These objectives where evaluated relationship...
Microalgae are commonly referred to as 'unicellular factories' due their size and capacity produce accumulate valuable biomolecules. The synthesis of a given biomolecule is generally triggered by external stimuli (e.g., light). This work evaluated the effect different types water nutrient sources (freshwater, wastewater, fertilisers, or pig slurry) on biochemical composition microalga Tetradesmus almeriensis produced pilot-scale. Overall, significant differences were observed in biomasses (p...
Microalgae are definitely on the way to become a sustainable, fast-growing natural green source for highly demanded market products. Research is currently looking at promising outstanding applications of microalgae among which production biofuels from fatty acids present in biomass, functional foods enriched with healthy bioactive molecules, and greenhouse gas mitigation (CO2 consuming) based high cell density cultures technology. Besides, other traditional increasing competitiveness growing...
Coccomyxa acidophila is an extremophile eukaryotic microalga isolated from the Tinto River mining area in Huelva, Spain. accumulates relevant amounts of b-carotene and lutein, well-known carotenoids with many biotechnological applications, especially food health-related industries. The acidic culture medium (pH < 2.5) that prevents outdoor cultivation non-desired microorganism growth one main advantages acidophile microalgae production. Conversely, rates are usually very low compared to...
High annual microalgae productivities can only be achieved if solar light is efficiently used through the different seasons. During winter productivity low because of and temperature conditions. The photosynthetic efficiency Chlorella sorokiniana were assessed under worst-case scenario found during time in Huelva, south Spain. maximum intensity (800 μmol photons m(-2) s(-1)) (20°C) simulated a lab-scale photobioreactor with short light-path 14 mm. Chemostat conditions applied results...
The large-scale biomass production is an essential step in the biotechnological applications of microalgae. Coccomyxa onubensis acidophilic microalga isolated from highly acidic waters Río Tinto (province Huelva, Spain) and has been shown to accumulate a high concentration lutein (9.7 mg g−1dw), valuable antioxidant, when grown at laboratory-scale. A productivity 0.14 g L−1 d−1 was obtained by growing under outdoor conditions 800 L tubular photobioreactor. results show stable for least one...
A heavy-metal-resistant, carotenoid-enriched novel unicellular microalga was isolated from an acidic river in Huelva, Spain. The ribosomal 18S subunit rDNA sequence showed homology with known sequences green microalgae, the closest (98% homology) belonging to genus Coccomyxa. therefore up now uncultured microalga. Tinto River area (Huelva, Spain), that exhibits very low pH (1.7-3.1) high concentrations of sulfuric acid and heavy metals, including Fe, Cu, Mn, Ni, Al. Electron micrographs show...
Abstract Photoautotrophic algal cultivation is challenging due to the shadowing effect produced by an increase in number of cells; under such circumstances, mixotrophic growth might be efficient alternative. We grew cultures autochthonous acidotolerant microalga Elliptochloris sp. on crude technical glycerin or glucose bubbled with either only air containing 2.5 % (v/v) CO 2 . found that strongly influenced production sp., as higher occurred mixotrophy -enriched compared air. Mixotrophy...
Coccomyxa onubensis (C. onubensis) is an acidotolerant microalga isolated from Tinto River (Huelva), which contains high levels of metal cations in solution, mainly Fe (II) and (III), Cu (II). more bioavailable at low pH, because (III) are far soluble, especially (III). For this reason, study aims to evaluate both physiological biochemical responses C. when subjected (III)-induced stress. Changes growth, photosynthetic viability antioxidant the induced oxidative stress were determined. The...
