Question

Air is fed into fermentor and it dissolve into

Answer 1

Air is fed into fermentor and it dissolves into the liquid phase. The rate of change of
the liquid phase oxygen concentration C(t) is proportional to the difference C*-C(t)
where C* is the oxygen concentration of a saturated liquid. C* depends on e.g. pH
and temperature, but it is assumed here to be constant 0.0013 mol/l. When fermentor
was started, C(t) was 0.0005 mol/l, i.e. C*-C(t) = 0.0008, and after 5 minutes it
was 0.0009 mol/l i.e. C*-C(t) = 0.0004

Answer 2

Answer:

Production on an industrial scale, requires growing microbes in very large vessels called fermentors.
