Prof. Catello Di Martino is a Professor at the Department of Agricultural, Environmental, and Food Sciences, University of Molise. He graduated in Biological Sciences at the University of Naples in 1981. In 1983, he was the winner of the competition for the 1st cycle of PhD in General Physiology at the consortium offices of the University of Naples and Bari for four years. In 1987, he successfully passed the exam for the PhD degree. In 1988, he was the winner of a competition for university researchers at the Faculty of Agriculture of the University of Molise where he took up service on 1 July 1989. From 1989 to today, he continues to carry out his research activity at the Department of Animal, Plant and Environmental Sciences of the Faculty of Agriculture of the University of Molise, in the field of nitrogen assimilation biochemistry, in particular of mechanisms of nitrate and ammonium assimilation, variations in the intracellular concentration of free amino acids, phosphate nucleotides, polyamine compounds as well as the synthesis of nitrogenous bioenergetic molecules such as NAD (P) and ATP in the plant cell. Currently, he is engaged in the study of symbiotic interactions and plant productivity between mycorrhizae and roots in different conditions of nitrogen and inorganic phosphate in the soil and of the biochemical aspects of malolactic fermentation of bacteria.
