Preservation
of
Culture
Pure
cultures
of
microorganisms
are
required
for
research
as
well
as
for
other
purposes.
For
this,
it
is
necessary
to
have
a
culture
collection.
The
methods
used
for
maintenance
and
preservation
should
conserve
all
the
characteristics
of
the
organisms.
Some
of
the
simple
methods
of
culture
maintenance
and
preservation
are
explained
in
other
sections.
