National Engineer in Biological Engineering graduated from the National School of Engineers of Sfax (ENIS) in Tunisia at 2005. I received a Technician degree in Food industrial Engineering from the High Institute of Food industry (ESIAT) at 2002 and a master's degree in Industrial Biotechnology from the National Institute of Applied Sciences & Technology of Tunis (INSAT) at 2007. At 2009, I started my first professional application at the Biotechnology Center of Borj-Cedriyya (CBBC) in Tunisia as a Laboratory Technician in purification and identification of bioactive molecules from different natural resources in Laboratory of BioActive Substances (LBAS). Since 2013, I am a Senior Scientific Research Engineer at the Biotechnology Center of Sfax (CBS) in the Laboratory of Microbial Biotechnology, Enzymes and Biomolecules (LMBEB). At the same place and at 2019, I proposed to my professor to start a scientific project on the use of bacteria in the improvement of cultures under stress for preparing a Ph.D. in Biology Engineering from INSAT. I achieved my Ph.D. at 2023. Today, I worked for three scientific projects: -          Project of plant biotechnology -          Project of animal probiotics -          Project of plant protection under Erwinia amylovora
