The
Streptomyces
coelicolor
gene
cluster
encoding
the
biosynthesis
of
the
isochromane
quinone
antibiotic
was
cloned
into
a
variety
of
other
Streptomyces
spp.
producing
different
isocheomane
quinines.
At
least
three
new
antibiotics
were
detected.
Clearly,
actinoradin,
a
novel
metabolite
present
in
the
Streptomyces
sp.,
is
subjected
to
further
or
different
modifications.
Thus,
a
new
class
of
antibiotics
such
as
2-norethyromycins
A,
B,
C
and
D
and
isovaleyl
spiramycin
are
synthesized. Biotechnology
is
going
to
be
the
next
scientific
revolution
after
the
industrial
revolution,
which
is
going
to
change
the
lives
and
future
of
humankind
on
this
earth.
The
ability
to
manipulate
genetic
material
to
achieve
specified
outcomes
in
living
organisms
promises
major
changes
in
many
aspects
of
modern
life.
