Abstract
A Gram-positive, rod-shaped, motile, endospore-forming strain, DXFW5T, was isolated from the rhizosphere soil of tomato. Strain DXFW5T grew at 20-50 °C (optimum, 25-37 °C), pH 5-8 (optimum, pH 7) and in the presence of 3 % NaCl. It was positive for catalase and oxidase. Phylogenetic analysis using 16S rRNA gene sequences showed this strain was most closely related to Paenibacillus timonensis DSM 16943T (98.0 %) and Paenibacillus barengoltzii DSM 22255T (97.4 %). The DNA G+C content was 52.9 mol%. The digital DNA-DNA hybridization values between strain DXFW5T and P. timonensis DSM 16943T, P. barengoltzii DSM 22255T and P. macerans DSM 24T were 33.1, 24.9 and 21.2 %, respectively. The average nucleotide identity values between strain DXFW5T and P. timonensis DSM 16943T , P. barengoltzii DSM 22255T and P. macerans DSM 24T were 86.93, 81.77 and 75.98 %, respectively. The major fatty acids were anteiso-C15 : 0 (55.1 %), iso-C16 : 0 (13.2 %) and C16 : 0 (10 %). The polar lipids of strain DXFW5T consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine two unidentified phospholipids and three unidentified lipids. MK-7 was the major isoprenoid quinone. Based on these results, it was concluded that the isolate represents a novel species of the genus Paenibacillus, for which the name Paenibacillus rhizolycopersici sp. nov. is proposed, with DXFW5T (=ACCC 61751T=JCM 34488T) as the type strain.

Abstract
Paenibacillus, rod-saped gram-positive endospores forming aerobic or facultative anaerobic bacteria, colonize diverse ecosystems and are involved in the biodegradation of cultural heritage assets. Biodeteriogenic microorganisms can be easily detected/identified by ribonucleic acid- fluorescent in situ hybridization RNA-FISH with specific probes. In this work, probes designed in silico were analyzed to calculate hybridization efficiency and specificity by varying the formamide concentration in the hybridization. The Pab489 probe showed excellent in silico performance with high theoretical maximum efficiency hybridization (99.99%) and specificity and was selected for experimental assays with target Paenibacillus sp. and non-target biodeteriogenic microorganisms. Results assessed by epifluorescence microscopy and flow cytometry revealed that, regardless of the formamide concentration, it was possible to observe that the Pab489-Cy3 probe had a similar signal intensity to the EUB338-Cy3 probe (positive control), so the presence of formamide, a highly toxic and carcinogenic compound used to aid the hybridization process, is not necessary. The designed probe used in FISH assays allows specific in situ identification of Paenibacillus spp. in microbial communities in a culture-independent way. This approach can be employed for screening Paenibacillus spp., showing great potential for future application in biodeterioration of heritage assets, in the search for Paenibacillus strains that produce compounds with biotechnological or medical potential.

Abstract
A strict aerobic bacterium, strain JW14T was isolated from soil in the Republic of Korea. Cells were Gram-stain-positive, non-endospore-forming and motile rods showing catalase-positive and oxidase-negative activities. Growth of strain JW14T was observed at 20-37 °C (optimum, 30 °C), pH 6.0-10.0 (optimum, pH 7.0) and in the presence of 0-2.0% NaCl (optimum, 0%). Strain JW14T contained menaquinone-7 as the sole isoprenoid quinone, anteiso-C15:0, C16:0 and iso-C16 : 0 as the major fatty acids (>10.0%), and diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, three unidentified aminophospholipids and an unidentified lipid as the major polar lipids. The cell-wall peptidoglycan of strain JW14T contained meso-diaminopimelic acid. The DNA G+C content of strain JW14T calculated from the whole genome sequence was 48.1 mol%. Strain JW14T was most closely related to Paenibacillus graminis DSM 15220T with 97.4% 16S rRNA gene sequence similarity. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain JW14T formed a distinct phyletic lineage from closely related type strains within the genus Paenibacillus. Based on the results of phenotypic, chemotaxonomic and molecular analyses, strain JW14T represents a novel species of the genus Paenibacillus, for which the name Paenibacillus agri sp. nov. is proposed. The type strain is JW14T (=KACC 21840T=JCM 34279T).

Abstract
Two nifH gene-harbouring bacterial strains were isolated from rhizospheres of different vegetable plants grown in different regions of northern PR China. The two strains possessed almost identical 16S rRNA gene sequences. The average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) values between the two strains were 99.21 and 93.6% respectively, suggesting they belong to one species. Based on 16S rRNA gene phylogeny, the two strains were clustered together with Paenibacillus rhizophilus 7197T, Paenibacillus sabinae T27T and Paenibacillus forsythiae T98T, but on a separate branch. Novelty of the species was confirmed by ANI and dDDH comparisons between the type strain 7124T and its closest relatives, since the obtained values were considerably below the proposed thresholds for the species delineation. The genome size of strain 7124T was 5.40 Mb, comprising 5050 predicted genes with a DNA G+C content of 52.3 mol%. The polar lipids contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and three unidentified lipids. The major cellular fatty acids were anteiso-C15 : 0 (52.9%) and C16 : 0 (23.4 %). Menaquinone-7 was reported as the major respiratory quinone. The diamino acid in the cell-wall peptidoglycan was found to be meso-diaminopimelic acid. Based on phylogenetic, genomic, chemotaxonomic and phenotypic data, the two isolates are considered to represent a novel species of the genus Paenibacillus, for which the name Paenibacillus apii sp. nov. is proposed, with 7124T (=DSM 103172T=CGMCC 1.15689T) as type strain.

Abstract
Biological growth represents one of the main threats for the conservation of subterranean cultural heritage. Knowledge of the conditions which favour the various taxonomic groups is important in delineating their control methods. Combining our experience regarding hypogea in Italy and the Republic of Korea, we aim to perform a critical review and comparison of the Biodeterioration Patterns (BPs) found, the materials used, and the conservative treatments applied. For this purpose, we focused on Etruscan tombs (Italy, 7th to 3th century BC) and the ancient tombs of the Baekje Dynasty (Republic of Korea, 6th to 7th centuries AD), most of which have been designated UNESCO World Heritage Sites, collecting original and bibliographic data as well as official documents. Results highlight the rich biodiversity of the bacterial and fungal species. Phototrophs were observed only in niches with sufficient light and the development of roots was also detected. Changes in humidity and temperature, the nature of the soil, nutrient accumulation, and vegetation above the hypogea along with human activities explain the different BPs. The effects of biocide treatments are also discussed, such as the emergence of dangerous fungal species. The shared data also enhance the role of overlaying tumuli and vegetation as well as protective barriers to reduce biological risk.

Abstract
Biodeterioration caused by filamentous fungi is often a threat to the architectural heritage (i.e. tombs and historic sites). To specifically understand the deterioration phenomena caused by microorganisms in tombs and how these are shaped due to various environmental factors, the fungal communities in the coffin chamber of the Chinese emperor Yang (BC 569-618) were investigated at different heights using denaturant gradient gel electrophoresis (DGGE) fingerprinting. The associated environmental conditions, such as humidity, temperature, height and illumination, were also assessed. The results showed that a great diversity of fungal species (Cordyceps, Fusarium, Harpochytrium, Emericellopsis, Volutella, Cladosporium, Stachybotrys, Trichoderma, Cochlonema and two unknown fungal species) was present in emperor Yang's coffin chamber. The predominant species were Stachybotrys, Fusarium, Trichoderma and Cochlonema. Redundancy analysis (RDA) indicated that humidity, temperature, height and illumination were the most significantly related factors shaping the fungal communities. Humidity showed the highest degree of variance description (19.2%) than all other environmental factors, followed by illumination (18.3%) and height (12.8%). Furthermore, fungal richness and diversity indices showed a positive correlation with humidity (p < 0.05). These results help in understanding the fungal community in tombs, promoting the mitigation of deterioration phenomena of such building heritage for the present and future.

Abstract
Microorganisms play vital roles in the natural decomposition of carcasses in aquatic systems. Using high-throughput sequencing techniques, we evaluated the composition and succession of microbial communities throughout the decomposition of rat carcasses in freshwater. A total of 4,428,781 high-quality 16S rRNA gene sequences and 2144 operational taxonomic units were obtained. Further analysis revealed that the microbial composition differed significantly between the epinecrotic (rat skins) and the epilithic (rocks) samples. During the carcass decomposition process, Proteobacteria became the dominant phylum in the epinecrotic, epilithic, and environmental (water) samples, followed by Firmicutes in the epinecrotic samples and Bacteroidetes in the epilithic and water samples. Microbial communities were influenced by numerous environmental factors, such as dissolved oxygen content and conductivity. Our study provides new insight about postmortem submersion interval (PMSI) estimation in aquatic environments.

Abstract
A Gram-stain-negative, rod-shaped, motile bacterial strain, designated 3-5-3T, was isolated from maize-cultivated soil artificially contaminated with cadmium, in Nanyang, Henan Province, China. Strain 3-5-3T was oxidase- and catalase-positive. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain 3-5-3T was affiliated with the genus
Paenibacillus
and most closely related to
Paenibacillus anaericanus
MH2T (96.5 % similarity). The average nucleotide identity and digital DNA–DNA hybridization values between 3-5-3T and the closely related species ranged 69.4–84.5 % and 18.1–18.4 %. The genomic G+C content was 53.8 mol%. Anteiso-C15 : 0 was the major fatty acid and MK-7 was the only menaquinone. The diamino acid in the cell-wall peptidoglycan contains meso-diaminopimelic acid. The polar lipid profile contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylmethylethanolamine, two unidentified glycolipids, two unidentified aminolipids, one unidentified phospholipid, one unidentified phosphoaminolipid and six unidentified lipids. On the basis of the results obtained in this study, strain 3-5-3T is considered to represent a novel species of the genus
Paenibacillus

Abstract
The Gram-positive rhizosphere bacterium Paenibacillus polymyxa promotes plant growth and produces various antibiotics. Herein, we review research on this species over the past two and a half decades, and focus on the mechanisms of P. polymyxa strain E681, isolated from barley roots in the South Korea in 1995. Strain E681 has outstanding growth-promoting effects on barley, cucumber, pepper, sesame, and Arabidopsis thaliana and produces antimicrobial compounds that protect plants against pathogenic fungi, oomycetes, and bacteria. Induced systemic resistance elicited by treating seeds or roots with strain E681 is a possible mechanism for protecting systemic plant tissues from biotic and other environmental stresses. Genome sequencing has broadened our horizons for antibiotic development and other industrial applications beyond agricultural use. At least six gene clusters for the biosynthesis of antibiotics have been discovered, including polymyxin (pmx), which was recently re-instated as an antibiotic of last resort against Gram-negative drug-resistant bacteria. Three groups of antibiotic synthetases include the gene clusters that encode one for the non-ribosomal peptide polymyxin, fusaricidin, and tridecaptin, another for the lantibiotic paenilan, and the third for a polyketide. We successfully introduced the pmx gene cluster into the surrogate host Bacillus subtilis and created polymyxin derivatives by domain swapping. Furthermore, various E681 derivatives, including a high fusaricidin producer and strains lacking multi-antibiotics production, have been constructed by random mutagenesis and genome engineering. Thus, E681 is an important bacterium that contributes to both plant and human health.

Abstract
A nitrogen-fixing, endospore-forming bacterium, designated strain L201T was isolated from the leaves of Bryophyllum pinnatum growing in South China Agricultural University. Phylogenetic analysis of the 16S rRNA gene sequence indicated that strain L201T is affiliated with the genus Paenibacillus, and closely related to Paenibacillus albidus Q4-3T (97.4%), Paenibacillus odorifer DSM 15391T (97.3%) and Paenibacillus borealis DSM 13188T (97.2%). The main fatty acids components was anteiso-C15:0 (48.1%). The predominant isoprenoid quinone was MK-7. The major polar lipids were found to be diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol. The G+C content of strain L201T was 43.9%. DNA-DNA relatedness between L201T and the reference strain was 29.8%. Biological and biochemical tests, protein patterns, genomic DNA fingerprinting and comparison of cellular fatty acids distinguished strain L201T from the closely related Paenibacillus species. Based on these data, the novel species Paenibacillus bryophyllum sp. nov. is proposed, with the type strain L201T(= KCTC 33951 T = GDMCC 1.1251 T).
