Multivariable optimization process of heterotrophic growth of Chlorella vulgaris
Geada, Pedro; Francisco, Diogo; Pereira, Francisco; Filipe Maciel; Madureira, Leandro; Barros, Ana; Silva, Joana L.; Vicente, A. A.; Teixeira, J. A.Microalgae have received increasing attention as one of the most promising feedstocks in the development of new healthier food products and different strategies have been attempted to improve their growth. However, the high production costs and low productivities, commonly associated with photoautotrophic growths, are still a big challenge. In this study, a two-step optimization strategy was carried out in orde...
Production of lipid rich-extracts from Chlorella vulgaris using ohmic heating
Madureira, Leandro; Avelar, Zita; Conde, Tiago; Couto, Daniela; Domingues, M. Rosário; Domingues, Pedro; Pereira, Ricardo Nuno CorreiaMicroalgae biomass is a promising raw material for several bioproducts suitable for food, energy and pharmaceutical industries. The aim of the present work was to optimize the extraction of bioactive compounds from Chlorella vulgaris using Ohmic Heating (OH). A rotatable central composite design for two factors was used to assess the effects of temperature and solvent (% ethanol in water) on lipid extraction yi...
Multivariable approach on growth of microalgae
Geada, Pedro; Madureira, Leandro; Francisco, Diogo; Maciel, Filipe; Silva, Joana L.; Vicente, A. A.; Teixeira, J. A.Despite the increasing interest in microalgal biomass and its high-value compounds, the number of products that successfully reach the market is still neglectable when compared to the high potential linked to these organisms. High production costs and low productivity both in terms of biomass and metabolites associated with microalgae growth are some of the causes hindering their widespread use and commercializ...
Algal proteins: Production strategies and nutritional and functional properties
Geada, Pedro; Moreira, Catarina; Silva, Maria João; Nunes, R.; Madureira, Leandro; Rocha, Cristina M. R.; Pereira, Ricardo Nuno Correia; Vicente, A. A.Animal-based proteins are the most consumed worldwide given their well-balanced nutritional composition. However, the growing demand for animal proteins will not be sustainable due to their low conversion efficiency and high environmental footprint. Specific consumers dietary restrictions and modern trends emphasize the importance of finding alternative sustainable non-animal sources to meet future food (and, i...
