Thermoacidophiles
- They
include
members
of
the
genera
like
Thermus
and
Sulpholobus.
The
members
of
sulphur
oxidising
genus,
Sulpholobus
on
the
basis
of
staining
reactions,
have
been
characterised
as
Gram
negative
spherical
cells.
The
cell
walls
of
Sulpholobus
lack
murein.
They
also
have
other
features
of
archaebacteria
including
rRNA
homology
and membrane
structure.
They
are
thermophiles
with
an
optimum
growth
temperature
of
70
-
75°C
Sulpholobus
spp.occur
in
hot,
