Synchronous
Growth -
A
growing
microbial
culture
contains
cells
dividing
asynchronously
and
the
properties
of
the
population
are
the
average
properties
of
the
individual
cells.
While
studying
cell
cycle
events
we
want
to
measure
changes
in
the
biochemical
features
of
individual
cells
and
we
therefore
need
to
amplify
the
physiological
events
by
producing
a
synchronously
dividing
culture
in
which
all
the
cells
divide
at
roughly
the
same
time.
There
are
two
methods
available
for
producing
the
synchronous
cultures.
1.
Induction
methods
- They
rely
on
synchronising
an
exponential
phase
culture
by
appropriate
and
usually
sudden
changes
in
the
environment,
such
as
alteration
in
temperature,
concentration
of
nutrients
or
illumination
for
photoautotrophs.
