The first part enables students to acquire a basic knowledge of the subject, through the study of the three main players in industrial microbiology: industrial microorganisms, industrial fermenters and industrial culture media. After acquiring the basic notions, the second part of the subject will discuss the various products of industrial fermentation, which are (i): microbial biomass: generally used as a source of proteins of unicellular origin, (ii): the industrial production of certain primary metabolites represented by amino acids, organic acids and biogases, and (iii) the industrial production of certain secondary metabolites represented by antibiotics, polysaccharides and vitamins. The teaching method used in this course is based on the use of simple and basic language, supported by examples. In addition, and in order to make the content more accessible to students, many illustrations in the form of simplified diagrams, photos and summary tables have been used. As a result, it is always encouraging and motivating to receive corrections, advice and recommendations from our teaching and research colleagues.enPublication pédagogique
