It
is
now
agreed
that
spore
formation
in
bacteria
is
a
form
of
differentiation
in
which
there
is
an
ordered,
temporal
sequence
of
events
and
a
degree
of
commitment.
The
process
however,
does
not
involve
a
reductive
division
as
in
the
sexual
spore
formation
in
encaryotes
The
ability to
produce
spores also
is
of
ecological
advantage
to
the
organism
as
it
enables
it
to
survive
under
adverse
conditions.
Thus
sporulation
normally
occurs under
condition
of
nutrients
depletion.
A
variety
of
factors
such
as
pH,
media composition,
ionic
strength,
aeration
etc,
are
known
to
affect
sporulation
