New Technologies To Generate Biohybrid Materials With Advanced Functional Properties


Spanish National Research Council (CSIC) and Interdisciplinary Platform for Sustainable Plastics towards a Circular Economy-SusPlast, Spain.



M. Auxiliadora Prieto received her Ph.D. in Pharmacy in the year 1996 from the Complutense University of Madrid. She was granted two EMBO fellowships. First, at the Federal Institute of Biotechnology, Germany, in the group of Prof. Kenneth Timmis. Then, as an EMBO Postdoc fellow at the Institute of Biotechnology, ETH Zürich, Switzerland, in the group of Prof. Bernard Witholt. Currently, she is a Full Professor at the Spanish National Research Council (CSIC) and the coordinator of the Interdisciplinary Platform for Sustainable Plastics towards a Circular Economy-SusPlast (www.susplast-csic.org), gathering eighteen Institutes of CSIC with thirty-five multidisciplinary researcher groups devoted to implementing plastic circularity. At the Biological Research Center-Margarita Salas (CIB-CSIC) she is the Head of the Polymer Biotechnology group as part of the Plant and Microbial Biotechnology Department. The group aims to explore and exploit the bacterial abilities to produce and degrade bio-based polymers (polyesters and bacterial cellulose) in order to contribute to global sustainability, using tools of synthetic biology and metabolic engineering. Prof. Prieto has participated in and coordinated many national and international projects and is the main inventor of eleven patents dedicated to the production of bio-based polymers. Prof Prieto has published more than 100 international scientific papers and is the Editor of Microbial Biotechnology (Wiley).


Biohybrid materials have recently grown in attention due to the enormous range of possibilities presented by a material that has the functionalities of living cells or simply enzymes supported on a scaffold. Among the non-living components, bacterial biopolymers have stood out as their properties can be engineered by microbial biotechnology tools through sustainable bioprocesses. Bacterial cellulose (BC) has aroused particular interest due to the highly porous fiber network formed during the static culture of bacteria, with a tremendous water-holding capacity. The high crystallinity of BC, together with its high purity, renewability, biodegradability, and biocompatibility, make this material unique for certain applications with high-quality requirements. The natural properties of these macromolecules can be tuned by strategies of materials science combined with microbial biotechnology based on synthetic biology and metabolic engineering that make use of microbial cells as factories, enabling the production of next-generation advanced materials with smart functional properties.

Keywords: Bacterial cellulose, functionalization.
