Culturew Media
A culture is any growth or cultivation of microorganisms. Cultivation is the process of inducing microbe to grow. The term culture is usually employed for a deliberate growth in the laboratory. Microbes are thus cultivated in vitro (Latin vitro=glass i.e. in flasks, tubes, vessels etc).
A pure
culture is
one
that
contains
only
a
single
kind
(species)
of
microbe.
To
culture
microbes
in
laboratory
we
require
the
preparation
of
substances
which
they
can
use
as
food.
Such
nutrient
preparations
which
microorganisms
can
use
as
food
are
called
culture
media.
.
Different
microorganisms
require
different
nutrient
materials.
Thus
culture
media
vary
in
form
and
composition,
depending
on
the
species
to
be
cultivated.
There
are
three
main
types
of
culture
media:
(i)
Natural
or
empirical
culture
media,
(ii)
Synthetic
or
defined
culture
media,
and
(iii)
Living
media.
