This review focuses on why bio-capacitance has developed to become the standard online method to estimate biomass in cell-based bio-manufacturing processes. There is now a good understanding behind the apparent divergence seen between bio-capacitance

In this study, a new rapid automated yeast cell counter was assessed. The cell counter (Aber Countstar) uses bright-field microscopy and a dye-exclusion method. This study's aim was to determine whether this method could be effectively employed in an

BACKGROUND In mammalian cell culture processes, viable cell density (VCD) is one of the most crucial parameters for monitoring of the current status of cell growth and protein production. Among the various real-time monitoring tools available for VCD

Background Dielectric spectroscopy (DS) has been used for over two decades to measure the live cell concentration of animal cells in bioreactors online. The technology measures the build up of charge around live cell membranes under the influence of

A ceramic cross-flow filter has been evaluated in a recycle loop connected to a bioreactor containing a viscous Streptomyces sp. broth. Because of the instability of the antibiotics formed, it would be advantageous to extract them continuously as the

Background Performing accurate sample analyses during the culture of mammalian cells is vital in order to track the number and viability of cells present. This allows operators to recognise when reagents may need to be added to maximise yield, harves

Process control systems are a valuable tool in the research, development, and production stages of biopharmaceuticals. They allow cell culture processes to optimise product production through monitoring and controlling of the inputs to the system (e.

Dielectric spectroscopy (DS) is routinely used in yeast and mammalian fermentations to quantitatively monitor viable biomass through the inherent capacitance of live cells; however, the use of DS to monitor the enzymatic break down of lignocellulosic
