Introduction to predictive microbiology.

Microbiology (nutrition, physiology, growth).
Course: heat transfer

Microbial growth:

Understand the concept of exponential growth and kinetic laws, in particular Monod's law.

Nutritional requirements and environmental impact:

Study the impact of factors such as temperature, pH, redox potential and food matrix on the growth of microorganisms.

Control and destruction of microorganisms:

Thermal methods for controlling microorganisms, kinetics of microorganism destruction.
Sterilization scales, Bigelow and Ball methods.
Other athermal techniques for controlling microorganisms.

Introduction to predictive microbiology and modeling:

Discover the basics of predictive microbiology and modeling (challenge tests, DLC).
