A method to reduce concentration of a VOC (volatile organic compound) in air in contact with a coated surface comprising: - providing a surface - encapsulation of whole microorganism of Pseudomonas putida in a sol-gel matrix - application of the obtained sol-gel matrix to the surface to form the coated surface - exposing the air to the coated surface. Procédé de réduction de la concentration d'un COV (composé organique volatil) dans l'air en contact avec une surface revêtue, comprenant les étapes suivantes : présentation d'une surface; encapsulation d'un micro-organisme entier de Pseudomonas putida dans une matrice sol-gel; application de la matrice sol-gel obtenue sur la surface pour constituer la surface revêtue; et exposition de l'air à la surface revêtue.
