Microalgae emerge as an eco-friendly solution for food, feed, pharmaceutical, energy, and environmental remediation, providing a diverse range of valuable biocompounds to address the growing global demand. However, light conditions pose substantial challenges, limiting their photosynthetic efficiency productivity. Light concentration manipulation provided by plasmonic effects, coupled with photobioreactor technology, may represent promising solution. This study aimed at evaluating impact new...
Downstream processes in microalgae, such as the extraction of high value-added compounds, are often hampered by intrinsic rigidity cell wall. The toughness this structure makes intracellular compounds less available for extraction, which means that disruption methods necessary to apply. Coelastrella sp. is a terrestrial microalga reveals be promising source bioactive compounds; however, due its extremely resistant wall, few and determination studies these have been performed. In order...
A significant fraction of the food produced worldwide is currently lost or wasted throughout supply chain, squandering natural and economic resources. Food waste valorization will be an important necessity in coming years. This work investigates ability to serve as a viable nutritional substrate for heterotrophic growth Chlorella vulgaris. The impact different pretreatments on elemental composition microbial contamination seven retail mixtures was evaluated. Among pretreatment methods...
Dunaliella salina is a promising source of β-carotene, widely employed in the food industry. This study aimed to evaluate sequential application Ionic Liquid (IL) cholinium oleate as an extraction solvent for D. β-carotene recovery and, sequentially, emulsifier emulsion-based products obtained therefrom. The IL was evaluated regarding its ability permeabilize cells and recover at different temperatures (25-65 °C) concentrations (0-46%). use greatly improved (>84%). already present extracts...
Microalgae have received increasing attention as one of the most promising feedstocks in development new healthier food products and different strategies been attempted to improve their growth. However, high production costs low productivities, commonly associated with photoautotrophic growths, are still a big challenge. In this study, two-step optimization strategy was carried out order maximize biomass Chlorella vulgaris strain used at industrial scale under heterotrophic conditions. From...
Microalgae are an eco-friendly and alternative source of several compounds that can be applied in numerous biotechnological branches such as cosmetics, food, or pharmaceutical industries. However, the commercialization products from microalgae has still some drawbacks, among which it is possible to highlight low biomass compounds' productivities at industrial level. The common strategies improve process cost-effectiveness cultivation essentially based on optimising nutrient needs...
Abstract In this work, a multivariate analysis was carried out, using Plackett–Burman (PB) design involving seventeen growth parameters, on carotenoids production of Pavlova gyrans ( p < 0.10). Each assay analysed regarding its content (mg g −1 ) fucoxanthin (Fx), diatoxanthin, diadinoxanthin, β-carotene (βCar), α-carotene, and the sum all individually (TCar). According to statistical analysis, modified medium formulations were developed for particular cases Fx, βCar, TCar. The study...
A multivariate optimization approach significantly improved Pavlova gyrans biomass production and its nutritional composition.
Dunaliella salina is a promising source of β-carotene, widely employed in the food industry. This study aimed to evaluate sequential application Ionic Liquid(IL) cholinium oleate as an extraction solvent for D. b-carotene recovery and, sequentially, emulsifier emulsion-based products obtained therefrom. The IL was evaluated regarding its ability permeabilize cells and recover at different temperatures (25-65ºC) concentrations (0-46%). use greatly improved (>84%). already present extracts...
Lichens are organisms constituted by a symbiotic relationship between fungus (mycobiont) and photoautotrophic partner (photobiont). produce several bioactive compounds; however, the biotechnological exploitation of this organism is hampered its slow growth. To start studying possibility exploiting lichens as alternative sources compounds, eighteen were collected in north Portugal order to isolate study bioactivity their photobionts. It was possible cultivate only eight Three them, LFR1, LFA2...
