Effect of aeration and agitation on the production of

Methods and Results: The P. sinclairii was cultivated under various aeration and agitation conditions in a 5 l stirred‐tank bioreactor. The highest mycelial biomass (30·5 g l −1) and EPS production (11·5 g l −1) were obtained at a high aeration rate (3·5 v.v.m.) and at a high agitation speed (250 rev min −1). The apparent viscosities

One of the main aims of agitation systems using stirred vessels is to maintain balanced quantities of substances in different phases based on concentration levels [].In cases where soluble solids are mixed, stirrers are used to increase interaction between the particles and avoid uneven accumulation at one point [].Flow streams in stirred

2018-9-1  The plots show the percentage time particles spent at different regions of the reactor for a particular cell concentration (0.16 g/l) and agitation speed (600 rpm). It is observed from Fig. 4 that for low concentration the intensity does not fall below 20% of the incident radiation anywhere in the reactor. It is only at high concentration that

Mammalian Cell Encapsulation in Alginate Beads

2017-6-29  The agitation rate during the emulsification is too low or too high for the alginate concentration or viscosity used: Increasing turbulence by increasing the agitation rate or adding baffles will decrease the bead size. The alginate concentration, the temperature, the vessel and impeller geometry will all impact the bead size obtained.
