Truepera
is one
genus
of
bacteria
in the family
Trueperaceae
from the
phylum
Dienococcus-Thermus
. Following
points
accounts for its characters:
These
strains
form orange/red
colonies
and have spherical-shaped
cells
.
Optimum growth
temperature
of about 50 °C.
Optimum pH for growth between about 7.5 and 9.5, and do not
grow
at pH below 6.5 or above pH
11
.2.
They are extremely resistant to
ionizing radiation
. For instance up to 60% of the cells can
survive
even after being
exposed
to 5.0
kGy
These strains are
chemo-organotrophic
and
aerobic
; do not grow in
Thermus
medium
under anaerobic
conditions
with or without nitrate as
electron acceptor
and
glucose
as a source of carbon and energy, but
ferment
glucose to
d-lactate
without
formation
of
gas
. They assimilate a large variety of sugars,
organic acids
and
amino acids
.
Species:
Truepera radiovictrix.
