Zooplankton Biomass in Ponds - Determination of Biovolume and Dry Weight
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2023 The aim of this study was to evaluate the possibility of using simple screening methods to determine zooplankton biomass in ponds. Among the applicable methods, we selected sedimentation determination of wet biomass and dry biomass determination. Of the 369 samples analysed, the median volumetric zooplankton biomass was 0.012 ml.l-1 and the median dry ...

Biotechnology Progress, EarlyView.Abstract Increasing protein therapeutics production by adopting intensified perfusion cultures places high demand on the mass transfer capabilities of single‐use bioreactors (SUB). Here, we compare these capabilities for four SUB designs against worst‐case O2 transfer requirements for supporting Chinese hamster ovary (CHO) perfusion cultures. Impact of
