Biography

Mayra Alejandra Mariño Bohórquez obtained a scientific initiation in Colombia, where she investigated the biodegradation of polycyclic aromatic hydrocarbons in aqueous solution by native strains of Pseudomonas sp. She continued her academic training in Brazil, where she completed a Master's Degree focusing on ethanol precipitation of glycosyl hydrolases. Subsequently, she obtained a PhD in Chemistry (2018), with a thesis on the preparation of nanocellulose from orange bagasse and immobilization of glycosyl-hydrolases using magnetic nanoparticles. This stage also included the spectroscopic characterization of nanomaterials and structural characterization of biomass. In the professional field, she was junior researcher in Chile (2018-2019), where she researched eutectic green solvents for the production of cellulose nanocrystals. She is currently finishing the execution of a postdoctoral project awarded in 2022 on nanocellulose and chitosan for the encapsulation of stem cells.
