More than 30 students coming from the High Schools IES Aljandic (Posadas, Cordoba) and IES Colonial (Fuente Palmera, Cordoba) have visited our Biotransformations Laboratory. The students performed a series of experiments in the field of biocatalysis (enzyme kinetics, immobilization, chromatographic analysis, etc.). They also visited other dependencies at the Institute of Catalysis (ICP-CSIC), in particular a laboratory of protein engineering, an anaerobic chamber, a continuous bioreactor and the cold room.
