---------------------------------------------------------------------------------------------------------------------------------
29
A Gram-positive-staining, rod-shaped, endospore-forming, aerobic bacterium (FJAT-17212T) was isolated
30
from the rhizosphere soil of a medical plant, Prunella vulgaris, in Wuyi mountain of China. Strain
31
FJAT-17212T grew at 10–50 °C (optimum 30 °C), pH 5–11 (optimum pH 7) and 0–6% (w/v) NaCl
32
(optimum 2%). Phylogenetic analyses based on 16S rRNA gene sequences showed that strain
33
FJAT-17212T was a member of the genus Bacillus and was most closely related to Bacillus
34
galactosidilyticus DSM 15595T (97.3 %). DNA–DNA relatedness between strain FJAT-17212T and B.
35
galactosidilyticus DSM 15595T was low (35.2% ± 2.3). Diagnostic diamino acid of the peptidoglycan of
36
strain FJAT-17212T was meso-diaminopimelic acid and the predominant isoprenoid quinone was MK-7
37
(80.8%). The major cellular fatty acids were iso-C15:0 (35.7%), anteiso-C15:0 (29.8%), iso-C14:0 (9.9%) and
38
iso-C16:0 (9.9%) and the G+C DNA content was 39.8 mol%. Phenotypic, chemotaxonomic and genotypic
39
properties clearly indicated that strain FJAT-17212T represents a novel species within the genus Bacillus,
40
for which the name Bacillus wuyishanensis sp. nov. is proposed. The type strain is FJAT-17212T ( = DSM
41
27848 T = CGMCC1.1 2709T).

44
Bacillus species contain rod-shaped, aerobic or facultative anaerobic, Gram-positive,
45
endospore-forming bacteria, which exhibited a wide range of physiological abilities that
46
enable them to live in every natural environment, such as soil, hot springs, water, marine
47
sediments or airborne dust (Berkeley, 2002). Bacillus species in the rhizosphere and
48
rhizoplane of plants have attracted a great deal of attention (Singh et al., 2014) and increasing
49
numbers of new species have been isolated, such as Bacillus rhizosphaerae sp. nov., an novel
50
diazotrophic bacterium isolated from sugarcane rhizosphere soil (Madhaiyan et al., 2011),
51
Bacillus methylotrophicus sp. nov., a methanol-utilizing, plant-growth-promoting bacterium
52
isolated from rice rhizosphere soil (Madhaiyan et al., 2010) and Bacillus koreensis sp. nov., a
53
spore-forming bacterium, isolated from the rhizosphere of willow roots in Korea (Lim et al.,
54
2006). It was of great significance that Bacillus species could have a role to further define the
55
diversity, ecology, and biocontrol activities in the promotion of plant growth and the
56
suppression of soil-borne pathogens (Kaki et al., 2013; Lee et al., 2014). In this study, a novel
57
isolate designated strain FJAT-17212T was isolated from the rhizosphere of Chinese medical
58
plant roots of Prunella vulgaris in Wuyi mountain of Fujian Province, China, describing its
59
phylogenetic and phenotypic characteristics for classification.
60
61
Strain FJAT-17212T was isolated from rhizosphere soil samples of Prunella vulgaris in Wuyi
62
mountain of Fujian Province, China. For isolation, the sample was suspended in sterilized
63
water, serially diluted, spread on nutrient agar (NA) and incubated at 30 °C for 48 h (Atlas
Liu et al.
64
1993). Pure cultures were obtained by several successive single colony isolations. The strain
65
was stored both on NA slants at 4 °C and as suspensions in Luria–Bertani broth (LB) with 20%
66
(v/v) glycerol at –80 °C. The reference strain Bacillus galactosidilyticus DSM 15595T was
67
obtained from the culture collections indicated and used as controls in the phenotypic tests.
68
69
For phenotypic tests, the isolate FJAT-17212T and B. galactosidilyticus DSM 15595T were
70
performed as described by Logan et al., (2009). Cell morphology was observed by light
71
microscopy (Leica DMI3000B, Germany). The Gram staining and the KOH lysis test were
72
carried out according to the methods described by Smibert & Krieg (1994) and Gregersen
73
(1978). Endospores were examined according to Schaeffer–Fulton staining method (Murray
74
et al. 1994). Motility was examined on motility agar (Chen et al., 2007). Catalase activity was
75
determined by investigating bubble production with 3% (v/v) H2O2, and oxidase activity was
76
determined using 1% (v/v) tetramethyl p-phenylenediamine (Chen et al., 2007). Cell growth
77
under anaerobic conditions was determined in a CO2 incubator on anaerobically prepared
78
maintenance medium. Physiological characteristics, such as Voges–Proskauer test, hydrolysis
79
of gelatin, arginine dihydrolase, lysine decarboxylase, ornithine decarboxylase, tryptophan
80
deaminase, and urease, citrate utilization, ONPG, H2S and indole production were performed
81
using API 20E strips (BioMérieux). Nitrate reduction, hydrolysis of casein, starch, Tween 20,
82
40, and 80 were determined as described by Cowan and Steel (1965), Smibert & Krieg (1994).
83
The tests of carbon source utilization and acid-production were performed using the API
84
50CHB system (BioMérieux). Growth at different temperatures (5–50 °C, in increments of
85
5 °C), pH (5.0–10.0, in increments of 1 pH units) and NaCl concentrations (0–10% (w/v), in
86
increments of 1% NaCl) was tested in NB medium, respectively.
87
88
For phylogenetic analysis, the 16S rRNA gene sequence was amplified by PCR with the
89
universal primers 27F (5'-AGAGTTTG ATCCTGGCTCAG-3') and 1492R (5'-GGTTACCTT
90
GTTACGACTT-3'). Amplification was carried out with a DNA thermal cycler (Gene Amp
91
PCR System 2700; Applied Biosystems) according to the following program: 95 °C for 10
92
min, 30 cycles of 94 °C for 0.5 min, 50 °C for 1 min and 72 °C for 2 min and final extension
93
at 72 °C for 10 min. PCR products were purified and sequenced by Shanghai Biosune
94
(Shanghai, PR China) with an Applied Biosystems automatic sequencer (ABI 3730). Pairwise
95
sequence similarities were calculated using a global alignment algorithm implemented in the
96
EzTaxon -e database (http://eztaxon-e.ezbiocloud.net/, Kim et al., 2012). After multiple
97
sequence alignment using CLUSTAL_X (Thompson et al., 1997), phylogenetic analysis was
3
Bacillus wuyishanensis sp. nov.
98
performed using MEGA version 4 (Tamura et al., 2007). Distances were calculated using
99
distance options according to the Jukes-Cantor model (Jukes & Cantor, 1969) and clustering
100
was performed with the neighbour-joining method (Saitou & Nei, 1987). Bootstrap analysis
101
by means of 1000 resamplings was used to evaluate tree topologies (Felsenstein, 1985).
102
103
For DNA–DNA hybridization, it was performed to determine the relatedness of isolate
104
FJAT-17212T to the reference strain using the optical renaturation method (De Ley et al.,
105
1970; Huß et al., 1983) with three replications. Hybridization of extracted DNA was carried
106
out using a DIG High Prime DNA Labeling and Detection Starter kit (Roche), according to
107
the manufacturer’s instructions, with a hybridization temperature of 40 °C (calculated with
108
correction for the presence of 50 % formamide).
109
110
For calculation of DNA G+C content, it was analysed by HPLC (Young Lin??), as described
111
by Shin et al. (1996). Genomic DNA was isolated according to Hopwood et al. (1985) and the
112
DNA G+C content was determined using the thermal denaturation method described by
113
Marmur & Doty (1962) using Escherichia coli K-12 DNA as calibration standard. ??
114
115
For measurement of chemotaxonomic characteristics, polar lipids were extracted and analysed
116
by two-dimensional TLC according to Minnikin et al. (1984). The respiratory quinone system
117
was extracted and determined by HPLC according to established methods (Nakagawa &
118
Yamasato, 1993). The stereoisomer of diaminopimelic acid in the peptidoglycan of isolate
119
FJAT-17212T was determined as described by Staneck & Roberts (1974).
120
121
For measurement of chemotaxonomic characteristics, constituents of peptidoglycan were
122
determined using the method of Hasegawa et al. (1983). Isoprenoid quinones were analyzed
123
by reversed-phase HPLC (Groth et al., 1996).
124
125
For the analysis of cellular fatty acids, strains were harvested after cultivation on TSA at
126
30 °C for 48 h and the cellular fatty acids in the cell walls were extracted and analysed
127
according to the standard protocol of the Microbial Identification System (MIDI; Microbial
128
ID) (Sasser, 1990). Extracts were analysed by GC (Agilent 7890) as described by Miller
129
(1982).
130

Liu et al.
132
133
Strain FJAT-17212T formed cream-yellow, smooth, flat, opaque, circular colonies and 2–9
134
mm in diameter on NA plates. The strain was Gram-positive, moderately halophilic and
135
facultatively alkaliphilic. Ellipsoidal endospores were formed and cells were motile
136
(Supplementary Fig. S1). The strain grew at salt concentrations in the range 0–6% (w/v) NaCl,
137
with optimum growth occurring at 2% (w/v) NaCl. Growth was observed at 10–50 oC
138
(optimum 30
139
catalase-positive and did not reduce nitrate to nitrite. The phenotypic properties that
140
differentiate strain FJAT-17212T from its closest phylogenetic neighbours are given in Table
141
1.
o
C) and pH 5.0–11 (pH 7.0). The strain was oxidase-negative and
142
143
144
An almost-complete 16S rRNA gene sequence (1440 bp) of the isolate was determined. The
145
neighbour-joining phylogenetic tree (Fig. 1) revealed that the isolate FJAT-17212T belongs to
146
the genus Bacillus. The type strain in the genus Bacillus with the greatest pairwise similarity
147
to the isolate was B. galactosidilyticus DSM 15595T (97.3% 16S rRNA gene sequence
148
similarity). The value is low enough (<98%) to justify defining the isolate as a representative
149
of a novel species (Devereux et al., 1990; Fry et al., 1991; Ko et al., 2006 ). These results are
150
also supported by phylogenetic tree reconstructed using maximum-parsimony algorithms
151
(Supplementary Fig. S2) and maximum-likelihood and maximum-parsimony method
152
(Supplementary Fig. S3). The isolate showed 35.2% ± 2.3 DNA–DNA relatedness to B.
153
galactosidilyticus DSM 15595T, which is lower than the cut-off point (70%) for the
154
delineation of novel species. These results support the view that strain FJAT-17212T
155
represents a novel species in the genus Bacillus (Stackebrandt & Goebel, 1994; Wayne,
156
1988).
157
158
The DNA G+C content was calculated to be 39.8 mol%, which is within the range for the
159
genus Bacillus (35.6%–44.8%; Yoon et al., 2001; Heyrman et al., 2004; Ten et al., 2007;
160
Zhang et al., 2010; Seiler et al., 2012). These characteristics confirm that strain FJAT-17212T
161
belongs to the genus Bacillus (Albert et al., 2007).
162
163
164
Strain FJAT-17212T contained MK-7 (80.8%) as the major menaquinone, with MK-6 (1.8%)
165
and MK-8 (14.9%) present as minor constituents. Analysis of the cell-wall peptidoglycan
5
Bacillus wuyishanensis sp. nov.
166
showed that the strain contained meso-diaminopimelic acid as the diagnostic diamino acid, as
167
it is typical of the vaste majority of members of the genus Bacillus (Priest et al., 1988).
168
169
The cellular fatty acid profile of the isolate comprised iso-C15:0 (35.7%), anteiso-C15:0 (29.8%),
170
iso-C14:0 (9.9%), iso-C16:0 (9.9 %) and anteiso-C17:0 (4.7%) as the major fatty acids (>4 %).
171
The fatty acid profile of the isolate is clearly qualitatively and quantitatively different from
172
this of the closest related type strain B. galactosidilyticus DSM 15595T (Table 1) with the
173
fatty acids iso-C15:0 (31.9%), C16:0 (21.5%), anteiso-C15:0 (17.5%), iso-C16:0 (5.8%), iso-C14:0
174
(4.2%) and C14:0 (4.0%) as major components.. Acid Summed Feature 1 and anteiso-C14:0
175
found in the isolate were not detected in strain B. galactosidilyticus DSM 15595T. These iso-
176
and anteiso-branched fatty acids of the 14– and 17-carbon series are typical of those observed
177
in profiles of the type strains of the genus Bacillus (Kämpfer, 1994; Albert et al., 2005).
178
179
Based on physiological, biochemical and phylogenetic properties, we consider the strain
180
FJAT-17212T represents a novel species of the genus Bacillus, for which we propose the name
181
Bacillus wuyishanensis sp. nov.
