Microalgae are a valuable source of high-value products and biofuels, however the high-energy cost required for the extraction of their metabolites has kept questioning on possible industrial upgrading. The aim of this study was to evaluate the effect of temperature, solvent/biomass, NaOH concentration and thermal pretreatment of the biomass in a 2-cycle carbohydrate and protein extraction system. Results shown that best conditions for carbohydrates extraction are achieved at a solvent concentration of 3.67 M, 55°C and a solvent/biomass ratio of 30mL/g. On the other side, the best conditions for protein were 3 M, 85°C and 45 mL/g. The efficiencies achieved under these conditions were 95% for carbohydrates and 98% for proteins. Using the best extraction conditions for each metabolite a thermal pre-treatment was performed at 25°C, 75°C and 105ºC. Results indicate that highest efficiencies were achieved with dry biomass pretreated at 105°C, with values of 95% for carbohydrates and 98% for proteins. application/pdf eng Chemical Engineering Transactions Derechos Reservados - Universidad de Santander https://creativecommons.org/licenses/by-nc/4.0/ info:eu-repo/semantics/openAccess Atribución-NoComercial 4.0 Internacional (CC BY-NC 4.0) https://www.researchgate.net/publication/301800845_Evaluation_of_a_Two-Phase_Extraction_System_of_Carbohydrates_and_Proteins_from_Chlorella_vulgaris_Utex_1803/link/5728cadf08aef7c7e2c0c6f3/download Evaluation of a two-phase extraction system of carbohydrates and proteins from chlorella vulgaris utex 1803 Artículo de revista http://purl.org/coar/resource_type/c_6501 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Text http://purl.org/redcol/resource_type/ART Carbohydrates Proteins Chlorella vulgaris http://purl.org/coar/access_right/c_abf2 http://purl.org/coar/version/c_970fb48d4fbd8a85 Publicationopen.access
