“…The genus Clostridium was detected in almost all of our soil samples; however, members of this genus are anaerobic and could therefore not be detected under our aerobic isolation conditions. The genera Acidovorax , Leifsonia , and Corynebacterium were rarely observed in the 30 soil samples, a finding that is in agreement with the isolation data [ 92 ]. Of the top 10 plant pathogenic bacteria [ 93 ] and the common bacterial diseases known to affect ginseng [ 94 – 95 ], only the genus Pseudomonas and the family Ralstonia were found in our samples.…”

“…Among the phytopathogenic potential bacteria identified in this study, the genera Sphingomonas , Arthrobacter , Bacillus , and Pseudomonas have been frequently isolated under laboratory conditions in the previous studies [ 89 – 92 ]. Many species belonging to the genus Sphingomonas have been shown to be able to convert ginsenosides [ 89 – 90 ].…”

Traditional molecular methods have been used to examine bacterial communities in ginseng-cultivated soil samples in a time-dependent manner. Despite these efforts, our understanding of the bacterial community is still inadequate. Therefore, in this study, a high-throughput sequencing approach was employed to investigate bacterial diversity in various ginseng field soil samples over cultivation times of 2, 4, and 6 years in the first and second rounds of cultivation. We used non-cultivated soil samples to perform a comparative study. Moreover, this study assessed changes in the bacterial community associated with soil depth and the health state of the ginseng. Bacterial richness decreased through years of cultivation. This study detected differences in relative abundance of bacterial populations between the first and second rounds of cultivation, years of cultivation, and health states of ginseng. These bacterial populations were mainly distributed in the classes Acidobacteria, Alphaproteobacteria, Deltaproteobacteria, Gammaproteobacteria, and Sphingobacteria. In addition, we found that pH, available phosphorus, and exchangeable Ca+ seemed to have high correlations with bacterial class in ginseng cultivated soil.

“…Phospholipid and lipid are also the common polar lipids found in Bacillus panacisoli, B. terrae and so on [34,35]. The absence of glycolipid and aminophospholipid in strain 3-2-2 T , also found in B. ginsengisoli, B. polymachus, Bacillus crescens and Bacillus solimangrovi [8,10,36,37], showed the difference from B. terrae Table 2. Results of average nucleotide identify (ANI, %), genome-togenome distance calculations (GGDC, %) from genome comparisons Strains: 1, 3-2-2 T ; 2, Bacillus fortis DSM 16012 T ; 3, Bacillus terrae LMG 29736 T LMG29736 T .…”

A Gram-stain-positive, rod-shaped, motile bacterial strain, designated 3-2-2 T , was isolated from field topsoil collected from a western suburb of Nanyang city, Henan province, China. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain 3-2-2 T was a member of the genus Bacillus and most closely related to Bacillus fortis R-6514 T (98.9 % similarity), Bacillus terrae RA9 T (98.0 %) and Bacillus fordii R-7190 T (97.7 %). A draft genome sequence determined for strain 3-2-2 T revealed a DNA G+C content of 42.2 mol%. The average nucleotide identity and digital DNA-DNA hybridization values between 3-2-2 T and the closely related Bacillus species ranged 79.4-84.2 % and 23.4-24.6 %. The major fatty acids of strain 3-2-2 T were iso-C 15 : 0 , anteiso-C 15 : 0 , iso-C 14 : 0 and iso-C 16 : 0. The major isoprenoid quinone was MK-7. meso-Diaminopimelic acid was detected in the peptidoglycan. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, an unidentified phospholipid and an unidentified lipid. The results of phylogenetic analyses, in silico genomic comparisons, and chemotaxonomic and phenotypic analyses clearly indicated that strain 3-2-2 T represents a novel species within the genus Bacillus, for which the name Bacillus acidinfaciens sp. nov. is proposed. The type strain is 3-2-2 T (=CGMCC 1.13685 T =LMG 30839 T).

: Endophytes are microorganisms that live in the internal tissues of plants without harming the host plants. In this symbiotic relationship, the host plants provide nutrients and shelter to the endophytes, in turn, endophytes can promote the growth of host plants and act as a biological control agents against plant pathogens. Plant-microbe interactions like this are noted for natural methods for sustainable agriculture and environmental conservation. However, in spite of the infinite potential, there are only a few reports on the endophytes present in ginseng. In this study, we isolated and identified the endophytes from Panax ginseng seeds and evaluated the biological activities (IAA production ability, nitrogen fixation ability, phosphate solubilization capacity, siderophore production ability, and antifungal activities) of the endophyte isolates. Eight different endophytes were identified by 16S rRNA sequencing. Most of the endophytes have antibiotic and plant growth promoting (PGP) activities. Particularly, PgSEB5-37E have the highest antibiotic activity, both PgSEB5-37B and PgSEB5-37H have high PGP traits such as an abilities to produce IAA, solubilize phosphate and fix nitrogen. These results indicated that the endophytes from P. ginseng seeds may have applicable value to many industries. In order to use the isolated endophytes, quantitative analysis and field tests are needed to be performed.
