DESCRIPTION OF
SERPENTINIMONAS BARNESII
SP. NOV.
Serpentinimonas barnesii
(bar.ne′ si.i. N.L. gen. n.
barnesii
, named after I. Barnes, geochemist and first describer of The Cedars serpentinization site).
In addition to the characteristics given above in the genus description, the
type
strain has the characteristics described below. Growth occurs at 18–37 °C and pH 9.0–12.0 with optimal growth at 30 °C and pH 11.0. NaCl ranges from
0 to 0.5g
l−1
. The DNA G+C composition of the
type
strain is 66.7mol% (determined from the genome). The strain grows autotrophically with hydrogen gas and calcium carbonate and heterotrophically on acetate, butyrate, lactate, pyruvate, ethanol and fumarate under microaerophilic conditions. The strain can ferment glucose. The strain is also able to utilize glucose as an electron donor, and nitrate as an electron acceptor. Major fatty acids are C
16:0
and C
18:1
ω7
c
. The respiratory quinone is ubiquinone.
The
type
strain,
H1
T
(=NBRC 111849
T
=DSM 103920
T
), was isolated from a highly alkaline serpentinizing spring (Barnes Spring 5) in
The Cedars
located in north
California
,
USA
.
