BINARY CONTROL OF FERMENTATION PROCESSES
Cybernetics and Systems, 2000In this paper a binary control for nonlinear and uncertain systems is proposed. In particular, continuous fermentation processes are considered. The control design is carried out with the direct use of a nonlinear model, expert knowledge, and an on-line measurement of output variable only. Asymptotic stability of the closed-loop systems in the presence

Control Applications in Fermentation Processes
Industrial & Engineering Chemistry, 1960Publisher Summary The potential use of programmed and cascade control systems in fermentations has not been fully realized. Heretofore, applications of control in fermentations have measured a single variable or a function thereof and then changed this variable by some means to obtain a correction.

Fluid Mixing in Fermentation Processes
Industrial & Engineering Chemistry, 1960Publisher Summary Mixing is an essential part of fermentation processes. There are two sources of fluid-mixing energy in a fermentation process; mixing impellers provide circulation of fluids through the tank, and the expansion and velocity of air passing through a fermentor imparts fluid motion.

Integrated fermentation and recovery processes
Current Opinion in Biotechnology, 1994The application of integrated fermentation and product recovery continues to be improved for products such as ethanol, acetone and butanol. An extractive fermentation process for ethanol has now been scaled up and is approaching commercialization. Integrated fermentation process design is expanding into higher value materials, such as amino acids ...

Importance of bacteriophages in fermentation processes
Acta Biotechnologica, 1989AbstractAny bacterial strain can be infected by virulent phages or harbour one or more prophages. Therefore, bacteria‐phage interactions are to be regarded as fundamental properties of bacteria. In current industrial fermentation processes phages can be advantageously employed for the identification of bacterial production strains (phage typing).

Fermentation Kinetics and Model Processes
Industrial & Engineering Chemistry, 1960Publisher Summary This chapter discusses fermentation kinetics particularly as they relate to batch processes, and continuous fermentation. Studies of batch fermentation processes in nearly all development programs involve periodic observations of growth, carbohydrate utilization, and product formation throughout the course of the fermentation ...
