Abstract Smart devices and tools, which are transferred into clean rooms, have a risk of surface contamination. Chemical disinfection can harm such devices and the process is prone to error due to the manual procedure. Therefore, a UVC-LED based disi

High throughput robotic systems have been used since the 1990s to carry out biochemical assays in microtiter plates. However, before the application of such systems in industrial fermentation process development, some important specific demands shoul

Oxygen limitation is one of the most frequent problems associated with the application of shaking bioreactors. The gas-liquid oxygen transfer properties of shaken 48-well microtiter plates (MTPs) were analyzed at different filling volumes, shaking di

Eine bisher fur das High Throughput Screening (HTS) nach neuen Biokatalysatoren eingesetzte Roboteranlage wurde derart modifiziert, dass sie nun auch fur Fermentationen im Mikromasstab eingesetzt werden kann. So steht eine vollautomatische Anlage zur

The turbidity of a microbial suspension sample is routinely determined by measuring the optical density (often referred to as the “absorbance”). This method requires a dilution step at moderate and high cell densities in order to ensure that meas

Oxygen supply is a key parameter in aerobic fermentation processes like the industrial production of amino acids. Although the oxygen transfer rate (OTR; or the volumetric oxygen transfer coefficient k(L)a) is routinely analyzed by engineers during s

Eight commercially available microplate sealing tapes and 10 other suitable materials (transparent wound dressings) are compared qualitatively in terms of their ability to minimize water evaporation from a multiwell plate while maintaining the oxygen
