The experimental results obtained for simulated broths indicated a considerable increase of kLa in the presence of n-dodecane, and the existence of a certain value ofn-d Dodecane concentration that corresponds to a maximum mass transfer rate of oxygen.
Studies on oxygen mass transfer in stirred bioreactors 2: Suspensions of bacteria, yeasts and fungis
The aim of these experiments is to study the oxygen mass transfer rate by means of the mass transfer coefficient, for a stirred bioreactor and different fermentation broths, using a large domain of…
Modeling of mixing in stirred bioreactors
Experimental research for determination of bisoprolol fumarate in human plasma samples using liquid chromatography- tandem mass spectrometry (LC-MS/MS) technique
The assay has proven to be sensitive, specific and reproducible, suitable to determine the bisoprolol concentration, following a single oral administration of a 10 mg bisopolol tablet in 22 healthy volunteers, in the bioequivalence study of Bisoprool 10 mg coated tablets.

Modeling of mixing in stirred bioreactors 4. mixing time for aerated bacteria, yeasts and fungus broths
The experimental data indicated that the influence of the rotation speed, aeration rate and stirrer positions on the mixing intensity strongly differ from one system to another and must be correlated with the microorganism characteristics, namely: the biomass concentration and morphology.
Rheology of fermentation broths. 1. Rheological behaviors and influencing factors
The rheological behavior of the fermentation hroths is one of the factors which influences decisively the performance of the biosynthesis processes. The medium viscosity combined with a non-Newtonian…
Disinfection reagents in prut river treatment for drinking water production.
The chlorine is the reagent of the widest application in disinfection processes of drinking water but it shows the short coming of reacting with the organic substances therein giving trihalomethanes…
