dc.description.abstractABSTRACT: Extremophilic environments are rich reservoirs for discovering microorganisms with vast biotechnological potential. Among these, microalgae stand out for their pivotal role in sustainable wastewater treatment and nutrient recycling. This study introduces Coelastrella thermophile D14, a microalga isolated from a solar panel, identified through morphological studies and genomic sequencing. The genus Coelastrella has been characterized and classified as highly productive strains valuable for biofuel and bioproduct generation as well as for their ability to produce significant amounts of carotenoids. Experiments revealed the extraordinary resilience of this strain to prolonged desiccation and high-strength piggery wastewater. Notably, D14 cultivated in 10% pig effluent exhibited biostimulant properties, achieving a germination index 23% higher than the control on Lepidium sativum. In a groundbreaking development, we have successfully established an Agrobacterium-mediated transformation protocol for C. thermophila D14, optimizing key parameters for effective T-DNA transfer. This marks a pioneering achievement within the genus Coelastrella. These findings highlight the significant potential of D14 as a robust platform for future biotechnological applications, opening new opportunities for innovative solutions, especially in environmental protection and sustainable agriculture.Key points center dot First microalga from solar panel biofilm: Coelastrella sp.
