The WhiteBiotech (industrial biotechnology) interdepartmental unit is a joint effort of active groups working in microbial biotechnology and protein science with a record of mutual collaboration at CIB. The mission of the WhiteBiotech unit is promoting excellence in knowledge transfer and innovation in applied biotechnology, acting as an accelerator for these activities at the National and European level.

The unit integrates front-line technologies and research strategies - including structural, molecular and chemical biology, computational (bio)chemistry, protein engineering, and systems and synthetic microbiology - to develop novel biotechnological products of interest for the bio-based and other industrial sectors, bulk and fine chemicals and pharmaceuticals included.

Our connection with these industrial sectors has a recognized international dimension, as shown by coordination of two large FP7 projects and one H2020 project of the BioBased Industries Joint-Undertaking (BBI-JU;, together with the recent involvement in six more BBI-JU and H2020 projects (and several ITN networks) and a score of related projects funded at national level.




The Interdepartmental Unit was created in 2012 (by a CSIC decision of 31 July) and, since its establishment date, has undergone several reorganizations as a result of the evolution of the CIB staff and the recommendations of the Scientific Committee, being currently constituted by de following 15 scientists/PIs: Sonsoles Martín Santamaría - Auxiliadora Prieto - Carmen Gil - Ana Martínez - Cristina Vega - Rafael Giraldo - Antonio Romero - Eduardo Díaz - Germán Rivas - María Jesús Martínez - Ángel T. Martínez (Coordinator) - Fernando Díaz - Miguel Angel Peñalva - (not in the picture: José Luis García - Ignacio Casal)

Research topics of the unit members are:

1) Microbial cell-factories for enzymes and metabolites of interest, Membrane trafficking and optimized secretion of fungal enzymes, Carbohydrate-acting enzymes (GHs, esterases and others), Fungal oxidoreductases, Rational design and directed molecular evolution of enzymatic biocatalysts

2) Crystallography and x-ray diffraction analysis, Protein science for drug design, Macromolecular interactions and synthetic cell-like environments

3) Microbial genomics and metagenomics, Advanced functional proteomics, Systems biology, Computational biology in enzyme and drug design    

4) Biotechnology for lignocellulose biorefineries, Degradation & valorization of lignin and carbohydrates, Bacterial metabolism of aromatics, steroids and other compounds, Bioplastics/biomaterials from renewable resources and wastes, Synthetic microbiology
