Abstract: | Summary Recycle lines have been widely used in on-line analysis of fermentation processes. However, like most tools, many practical considerations can remain overlooked. Upon reflecting on this technique, some of these overlooked considerations have been studied. Because of the importance of a debubbler to a recycle line, an improved design was made and tested which can produce a bubble free high flow rate stream to reduce residence times. The effect of the recycle line on the culture growth, and DO was also investigated and found to be negligible. |
