The use of heat- and alkali-resistant bacteria is essential for
the biological repair of damaged concrete. Lysinibacillus boronitolerans
YS11 was isolated from the rhizosphere of Miscanthus
sacchariflorus. The increased pH in the urea-minus
condition during the growth of the YS11 strain promoted calcium
carbonate (CaCO3) formation. To identify the optimum
medium that promoted the growth of the YS11 strain, a Plackett-
Burman design was conducted for the screening process.
Consequently, malt powder, rice bran, (NH4)2SO4, and corn
syrup were chosen to enhance YS11 growth. The optimization
of these four useful factors was carried out using a central
composite design. To obtain higher survivability in mortar,
the sporulation process is essential, and additional factors
such as Mn2+, Fe2+, and Ca2+ were found to contribute
to sporulation. A mixture of L. boronitolerans YS11 spore
powder, cement, paste, sand, yeast extract, calcium lactate,
and water showed a healing effect on a 0.3 mm mortar crack
in 7 days. Furthermore, calcium carbonate precipitation was
observed over the crack surface. Thus, we confirmed that mortar
treated with YS11 spore powder was effective in healing
micro-cracks in concrete.

Abstract

A Gram-stain-positive, oxidase- and catalase-positive, motile,
aerobic, and rod-shaped bacterial strain, designated as
DCT-5T, was isolated from a native plant belonging to the genus
Campanula at Dokdo island, Republic of Korea. Growth
of the strain DCT-5T was observed at 15–37°C (optimum
30°C) on R2A broth, pH 6.0–8.0 (optimum 7.0), and 0–5%
(w/v) NaCl concentration (optimum 0%). The 16S rRNA gene
sequence analysis revealed that strain DCT-5T was most closely
related to Arthrobacter silviterrae KIS14-16T, Arthrobacter
livingstonensis LI2T, Arthrobacter stackebrandtii CCM
2783T, Arthrobacter cryoconiti Cr6-08T, Arthrobacter ramosus
CCM 1646T, and Arthrobacter psychrochitiniphilus GP3T with
pairwise sequence similarities of 98.76%, 97.47%, 97.25%,
97.11%, 97.11%, and 97.00%, respectively. The DNA G+C
content of strain DCT-5T was 64.7 mol%, and its DNA–DNA
relatedness values with A. silviterrae KIS14-16T, A. livingstonensis
LI2T, A. stackebrandtii CCM 2783T, A. psychrochitiniphilus
GP3T, A. ramosus CCM 1646T, and A. cryoconiti
Cr6-08T were 32.57 ± 2.02%, 28.75 ± 0.88%, 31.93 ± 1.15%,
34.73 ± 1.86%, 29.12 ± 1.56%, and 27.23 ± 0.88%, respectively.
The major quinone was MK-9(H2) and major fatty acids were
anteiso-C15:0, anteiso-C17:0, iso-C15:0, and iso-C16:0. The polar
lipids were diphosphatidylglycerol (DPG), phosphatidylglycerol
(PG), phosphatidylinositol (PI), unidentified glycolipid
(GL), two unidentified aminophospholipids (APLs), and three
unidentified lipids (Ls). The peptidoglycan type was A3α.
On the basis of phenotypic, phylogenetic, genotypic, and chemotaxonomic
characteristics, strain DCT-5T represents a
novel species of the genus Arthrobacter, for which the name
Arthrobacter dokdonellae sp. nov. is proposed. The type strain
is DCT-5T (= KCTC 49189T = LMG 31284T).

Abstract

The novel Gram-stain-negative, rod-shaped, aerobic bacterial
strain DCR-13T was isolated from a native plant belonging
to the genus Campanula on Dokdo, an island in the
Republic of Korea. Comparative analysis of the 16S rRNA
gene sequence indicated that this strain is closely related to
Paraburkholderia peleae PP52-1T (98.43% 16S rRNA gene sequence
similarity), Paraburkholderia oxyphila NBRC 105797T
(98.42%), Paraburkholderia sacchari IPT 101T (98.28%), Paraburkholderia
mimosarum NBRC 106338T (97.80%), Paraburkholderia
denitrificans KIS30-44T (97.46%), and Paraburkholderia
paradise WAT (97.45%). This analysis of the 16S
rRNA gene sequence also suggested that DCR-13T and the
six closely related strains formed a clade within the genus
Paraburkholderia, but that DCR-13T was clearly separated
from the established species. DCR-13T had ubiquinone 8 as
its predominant respiratory quinone, and its genomic DNA
G + C content was 63.9 mol%. The isolated strain grew at a
pH of 6.0–8.0 (with an optimal pH of 6.5), 0–4% w/v NaCl
(with an optimal level of 0%), and a temperature of 18–42°C
(with an optimal temperature of 30°C). The predominant
fatty acids were C16:0, summed feature 8 (C18:1 ω7c/C18:1 ω6c),
C17:0 cyclo, C19:0 cyclo ω8c, summed feature 3 (C16:1 ω6c/C16:1
ω7c) and summed feature 2 (C12:0 aldehyde), and the major
polar lipids were phosphatidylglycerol and phosphatidylethanolamine.
On the basis of polyphasic evidence, it is proposed
that strain DCR-13T (= KCTC 62811T = LMG 30889T)
represents the type strain of a novel species, Paraburkholderia
dokdonella sp. nov.

Strain DCT-19T, representing a Gram-stain-positive, rodshaped,
aerobic bacterium, was isolated from a native plant
belonging to the genus Campanula on Dokdo, the Republic of
Korea. Comparative analysis of the 16S rRNA gene sequence
showed that this strain was closely related to Paenibacillus
amylolyticus NRRL NRS-290T (98.6%, 16S rRNA gene sequence
similarity), Paenibacillus tundrae A10bT (98.1%), and
Paenibacillus xylanexedens NRRL B-51090T (97.6%). DNADNA
hybridization indicated that this strain had relatively
low levels of DNA-DNA relatedness with P. amylolyticus
NRRL NRS-290T (30.0%), P. xylanexedens NRRL B-51090T
(29.0%), and P. tundrae A10bT (24.5%). Additionally, the genomic
DNA G + C content of DCT-19T was 44.8%. The isolated
strain grew at pH 6.0–8.0 (optimum, pH 7.0), 0–4%
(w/v) NaCl (optimum, 0%), and a temperature of 15–45°C
(optimum 25–30°C). The sole respiratory quinone in the strain
was menaquinone-7, and the predominant fatty acids were
C15:0 anteiso, C16:0 iso, and C16:0. In addition, the major polar
lipids were diphosphatidylglycerol and phosphatidylethanolamine.
Based on its phenotypic properties, genotypic distinctiveness,
and chemotaxonomic features, strain DCT-19T
is proposed as a novel species in the genus Paenibacillus, for
which the name Paenibacillus seodonensis sp. nov. is proposed
(=KCTC 43009T =LMG 30888T). The type strain of
Paenibacillus seodonensis is DCT-19T.

A rod-shaped, white color colony with lobate architectures,
strain h2T was isolated from a moderately acidic soil on Jeju
Island, Republic of Korea. Comparative analysis of the 16S
rRNA gene sequence showed that the strain h2T is closely
related to Paenibacillus relictisesami DSM 25385T (97.4%,
16S rRNA gene sequence similarity), Paenibacillus azoreducens
KACC 11244T (97.2%), and Paenibacillus cookii LMG
18419T (97.0%). DNA-DNA hybridization indicated that the
strain h2T has relatively low levels of DNA-DNA relatedness
with respect to P. relictisesami DSM 25385T (10.2%) and P.
azoreducens KACC 11244T (13.7%). Additionally, the genomic
DNA G + C content of h2T is 51.5 mol%. The isolated strain
grew at pH 4.0–9.0 (optimum, pH 6.0–7.0) and 0–5% (w/v)
NaCl (optimum, 0%) and a temperature of 15–45°C (optimum
35°C). The quinones in the strain are MK-6 and MK-7,
and the predominant fatty acid is C15:0 anteiso (32.1%) followed
by C17:0 anteiso (26.5%), and C16:0 iso (21.0%). Based
on its phenotypic properties, genotypic distinctiveness, and
chemotaxonomic features, strain h2T is proposed as a novel
species in the genus Paenibacillus, for which the name Paenibacillus
albilobatus sp. nov. is proposed (= KCCM 43269T =
JCM 32395T = LMG 30408T). The type strain of Paenibacillus
albilobatus is h2T.
