Probing control in B. licheniformis fermentations

Ola Johnsson, Jonas Andersson, Charlotta Johnsson


This paper presents the implementation of the probing control technique in
an industrially relevant fed-batch fermentation process utilizing the microorganism Bacillus lichenifor has been done in pilot-scale experiments. The aim of the work is firstly to find out whether it is posuccessfully implement probing control in B. licheniformis fermentations. Secondly, it is to find out whing control can improve process stability (defined as the ability to avoid process crashes) while achield at least as high as in the current process. In addition to presenting a successful outcome in regardaims, the paper also discusses possible process improvements and suggests a new type of probing control
