For chemotaxonomic studies, strain No.164T and reference
strains were grown in LB broth in a shaking incubator at
150 r.p.m., 28 uC for 4 days. The cell material was harvested
by centrifugation and washed twice with 0.9 % NaCl solution
and freeze-dried. All chemotaxonomical analyses were conducted under standardized conditions with strain
No.164T and cultures of the same set of reference strains
as listed above for the phenotypic characterizations. The
extraction and analysis of cellular fatty acids was carried out
from biomass grown on marine agar plates at 28 uC for
3 days and harvested from the last quadrant streak. Analysis
was conducted using the Microbial Identification System
(MIDI) Sherlock Version 6.1 (method TSBA40 database)
as described by Sasser (1990). Fatty-acid patterns were
visualized as a heat map using the lipid extensions of the
opm package (Vaas et al., 2013). Polar lipids were extracted,
separated by two-dimensional TLC and identified according
to procedures outlined by Minnikin et al. (1984) with modifications
proposed by Kroppenstedt & Goodfellow (2006).
Menaquinones (MK) were extracted from freeze-dried cell
material using methanol as described by Collins et al. (1977)
and analysed by HPLC (Kroppenstedt, 1982).
