Bacteria
show
characteristic
type
of
growth
on
solid
media
under
appropriate
cultureal
conditions
and
the colony
morphology can
be
used
in
presumptive
identification.
The
colonies
can
be
varying
in
size
and
diameter,
in
outline
(
circular,
wavy,
rhizoid
etc.)elevation
(flat,
raised,
convex,
etc.)
and
translucency
(
transparent,opaque,translucent).
The
colour
of
the
colony
or
the
changes
that
they
bring
about
in
their
surroundings
are
also
used
as
diagnostic
tools
in
the
tentative
identification
of
the
bacteria.
