Nicotiana tabacum cells are cultured to high density for
production of polysaccharide gum. The reactor used is a stirred tank,
containing initially 100 litres medium. The maximum specific growth rate of the
culture is 0.18 d-1 and the yield of biomass from substrate is 0.5 g
g-l. The concentration of growth-limiting substrate in the medium is
3% (w/v). The reactor is inoculated with 1.5 g l- 1 cells and
operated in batch until the substrate is virtually exhausted; medium flow is
then started at a rate of 4 l d-1. Fed-batch operation occurs under
quasi-steady-state conditions. Estimate final biomass concentration?
