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 the batch culture time. ____________________

A duck egg is removed from its mother’s nest and incubated by a barnyard hen. The duckling hatches out in the presence of the barnyard hen and stays in her nest. After a couple of days, the duckling is presented with a choice between its biological mother and the hen that incubated it. The duckling approaches and follows the hen. This set of observations demonstrates the phenomenon of
