TY - NEWS TI - Use of mining effluents for the production of algal-based colorants AU - Perez-Roa, Michael Edgardo AU - Ortiz Alvarez, Maria Daniela AU - García-Martinez, Janet AU - Barajas Solano, andres F AU - Barajas-Solano, Crisostomo AB - In this research, a mining effluent was used to produce microalgal and cyanobacterial bio-mass to obtain red (carotenoids) and blue pigments (phycocyanin). Two strains were isolated from a hydrothermal source in Norte de Santander and grown in mining wastewater mixed with 50% BG-11 medium for the Osci_UFPS01 cyanobacterium and 50% with Bold Basal me-dium for the Chlo_UFPS01 microalgae. A carbon, nitrogen, and phosphorus experiment de-sign was developed, and subsequent response surface analysis (RSM) was used to determine the optimal operating conditions for the formation of the products of interest. A notable de-crease in pigment production was observed compared to that in the controls without mining wastewater. Overall, 45% of phycocyanin (C PC) per unit dry weight (DW) and 1,129% (w/w) of carotenoids were obtained in the cultures with a mining wastewater mixture in the final optimization processes DA - 2024-08-11 PB - Ingeniería y Competitividad UR - https://repositorio.ufps.edu.co/handle/ufps/9147 ER -
