AERATION and AGITATION
important position of oxygen
depends on C-sources
what are the C-sources for microorganisms?
calculation for [Oxygen required] :red_flag: SL9
effect of DOC on oxygen uptake
Step 1 to 3
OTR = d CL/ d t = KL . a( C* -CL)
CL: the concentration of dissolved oxygen in the fermentation broth (mmol/l) (measurement with oxygen-electrode)
KL . a
how to determine this combination?
factors effect K L . a
vicosity // rheology

vicosity is a complex characteristic and affects the fermentation. [does not need to remember how to calculate it] :red_flag:
