Microbial resources and industrial microbial processes design and behavior

The large diversity in the microorganisms explain why they are involved in many industrial microbial processes. The industrial microbial processes concern fermented food preparations, microbial cell and metabolite productions and wastes processing. They are made in fundamentally the same way with three steps: pretreatment of raw matter, microbial conversion, and product recovery. The obtaining an efficient process is based on the control of the environmental conditions and the limiting substrate concentration influencing the microbial metabolism. Microbial process design should take into account specific biological and technological constraints and minimize the cost of product during production and downstream operations.
