Abstract PDF Supplementary Material: Korean Red ginseng has emerged as a potent candidate in the fight against various viral infections, demonstrating significant efficacy both in vitro and in vivo, particularly against influenza A viruses. Despite substantial evidence of its antiviral properties, the detailed molecular mechanisms through which it reduces viral lethality remain insufficiently understood. Our investigations have highlighted the superior effectiveness of Korean Red ginseng against influenza viruses, outperforming its effects on numerous other viral strains. We aim to uncover the specific mechanisms by which Korean Red ginseng exerts its antiviral effects, focusing on influenza A viruses. Our prior studies have identified the role of Z-DNA-binding protein 1 (ZBP1), a signaling complex involved in inducing programmed cell death in response to influenza virus infection. Given the critical role of ZBP1 as a sensor for viral nucleic acid, we hypothesize that Korean Red ginseng may modulate the ZBP1-derived cell death pathway. This interaction is anticipated to enhance cell death while concurrently suppressing viral protein expression, offering novel insights into the antiviral mechanism of Korean Red ginseng against influenza A viruses.

A Gram-negative, non-motile, aerobic, catalase-, and oxidasepositive bacterial strain, designated DCY117T, was isolated from ginseng cultivated soil in Gochang-gun, Republic of Korea, and was characterized taxonomically using a multifaceted approach. 16S rRNA gene sequence analysis revealed that strain DCY117T showed highest similarity to Lysobacter ruishenii CTN-1T (95.3%). Phylogenetic analysis revealed that closely related relatives of strain DCY117T were L. aestuarii S2-CT (95.1%), L. daejeonensis GH1-9T (95.0%), and L. caeni BUT-8T (94.9%). Diphosphatidylglycerol (DPG), phosphatidylglycerol (PG), and phosphatidylethanolamine (PE) were the major polar lipids of strain DCY117T. The major isoprenoid quinone was Q-8. The major cellular fatty acids of strain DCY117T were iso-C15:0, iso-C16:0, and summed feature 9 (comprising iso-C17:1 ω9c and/or 10-methyl-C16:0). Genomic DNA G + C content was 61.8 mol%. On the basis of our findings, strain DCY117T is a novel species in the genus Lysobacter. We propose the name Lysobacter panacihumi sp. nov., and the type strain is DCY117T (= KCTC 62019T = JCM 32168T).

Abstract

A Gram-positive, strictly aerobic, nonmotile, yellowish, coccus- rod-shaped bacterium (designated Gsoil 653T) isolated from ginseng cultivating soil was characterized using a polyphasic approach to clarify its taxonomic position. The strain Gsoil 653T exhibited optimal growth at pH 7.0 on R2A agar medium at 30°C. Phylogenetic analysis based on 16S rRNA gene sequence similarities, indicated that Gsoil 653T belongs to the genus Terrabacter of the family Humibacillus, and was closely related to Terrabacter tumescens DSM 20308T (98.9%), Terrabacter carboxydivorans PY2T (98.9%), Terrabacter terrigena ON10T (98.8%), Terrabacter terrae PPLBT (98.6%), and Terrabacter lapilli LR-26T (98.6%). The DNA G + C content was 70.5 mol%. The major quinone was MK-8(H4). The primary polar lipids were phosphatidylglycerol, diphosphatidylglycerol, phosphatidyl-ethanolamine. The predominant fatty acids were iso-C15:0, iso-C16:0, iso-C14:0, and anteiso-C15:0, as in the case of genus Terrabacter, thereby supporting the categorization of strain Gsoil 653T. However, the DNA-DNA relatedness between Gsoil 653T and closely related strains of Terrabacter species was low at less than 31%. Moreover, strain Gsoil 653T could be both genotypically and phenotypically distinguished from the recognized species of the genus Terrabacter. This isolate, therefore, represents a novel species, for which the name Terrabacter ginsengisoli sp. nov. is proposed with the type strain Gsoil 653T (= KACC 19444T = LMG 30325T).

Abstract

A taxonomic study was conducted on BR7-21T, a bacterial strain isolated from the soil of a ginseng field in Baekdu Mountain. Comparative studies of the 16S rRNA gene sequence showed that the isolate was most closely related to Conexibacter woesei DSM 14684T, Solirubrobacter pauli ATCC BAA-492T, Patulibacter minatonensis JCM 12834T, with 93.8%, 92.4%, and 91.5% sequence similarity, respectively; each genus represented a family in the order Solirubrobacterales. Strain BR7-21T was Gram-reaction positive, non-spore forming, aerobic, non-motile, and short rod-shaped. It grew well on half-strength R2A medium. The G + C content of the genomic DNA was 73.9%. It contained meso-diaminopimelic acid in the cell wall and the major menaquinones were MK-7(H4) and MK-8(H4). The major fatty acids were summarized as (C16:1 ω7c/iso-C15:0 2-OH), iso-C16:0, and C17:0 cyclo. On the basis of polyphasic evidence, it was proposed that strain BR7- 21T should be placed in a new genus and species, for which the name Baekduia soli gen. nov., sp. nov. was proposed with the type strain BR7-21T (= KCTC 22257T = LMG 24797T). The family Baekduiaceae fam. nov. is proposed to encompass the genus Baekduia gen. nov.

Abstract

A novel strain DCY105T was isolated from soil collected from the rhizosphere of ginseng (Panax ginseng), in Gochang, Re-public of Korea. Strain DCY105T is Gram-reaction-negative, white, non-motile, non-flagellate, rod-shaped and aerobic. The bacteria grow optimally at 30°C, pH 6.5–7.0 and in the absence of NaCl. Phylogenetically, strain DCY105T is most closely related to Achromobacter marplatensis LMG 26219T (96.81%). The DNA G+C content of strain DCY105T was 64.4 mol%. Ubiquinone 8 was the major respiratory quinone, and phosphatidylethanolamine, phosphatidylglycerol, and dipho-sphatidylglycerol were amongst the major polar lipids. C16:00, C8:03OH and iso-C17:03OH were identified as the major fatty acids present in DCY105T. The results of physiological and biochemical tests allowed strain DCY105T to be differentiated phenotypically from other recognized species belonging to the genus Achromobacter. Therefore, it is suggested that the newly isolated organism represents a novel species, for which the name Achromobacter panacis sp. nov. is proposed with the type strain designated as DCY105T (=CCTCCAB 2015193T =KCTC 42751T).

Abstract: Endophytic bacteria have been found in virtually every plant studied, where they colonize the internal tissues of their host plant and can form a range of different beneficial relationships. The diversity of bacterial endophytes associated with ginseng plants of varying age levels in Korea was investigated. Fifty-one colonies were isolated from the interior of ginseng stems. Although a mixed composition of endophyte communities was recovered from ginseng based on the results of 16S rDNA analysis, bacteria of the genus Bacillus and Staphylococcus dominated in 1-year-old and 4-year-old plants, respectively. Phylogenetic analysis revealed four clusters: Firmicutes, Actinobacteria, α-Proteobacteria, and γ-Proteobacteria, with Firmicutes being predominant. To evaluate the plant growth promoting activities, 18 representative isolates were selected. Amplification of nifH gene confirmed the presence of diazotrophy in only two isolates. Half of the isolates solubilized mineral phosphate. Except four, all the other endophytic isolates produced significant amounts of indole acetic acid in nutrient broth. Iron sequestering siderophore production was detected in seven isolates. Isolates E-I-3 (Bacillus megaterium), E-I-4 (Micrococcus luteus), E-I-8 (B. cereus), and E-I-20 (Lysinibacillus fusiformis) were positive for most of the plant growth promoting traits, indicating their role in growth promotion of ginseng.

Abstract: A Gram-positive, rod-shaped, non-spore-forming bacterium (Gsoil 485T) was isolated from the soil of a ginseng field located in Pocheon province in South Korea. This bacterium was characterized in order to determine its taxonomic position by using the polyphasic approach. On the basis of 16S rRNA gene sequence similarity, strain Gsoil 485T was shown to belong to the family Nocardioidaceae and related to Nocardioides koreensis (96.8% 16S rRNA gene sequence similarity), Nocardioides basaltis (96.7%), Nocardioides salarius (96.7%), and Nocardioides sediminis (96.5%). The sequence similarity with other species that had validly published names within the genus Nocardioides was less than 96.4%. Strain Gsoil 485T was characterized chemotaxonomically as having LL-2,6-diaminopimelic acid in a cell-wall peptidoglycan, MK-8(H4) as the predominant menaquinone, and iso-C16:0, C18:1 ω9c as the major fatty acids. The G+C content of genomic DNA was 71.6 mol%. The chemotaxonomic properties and phenotypic characteristics supported the affiliation of strain Gsoil 485T to the genus Nocardioides. The results of both physiological and biochemical tests allowed for genotypic differentiation of strain Gsoil 485T from the recognized Nocardioides species. Therefore, strain Gsoil 485T is considered to represent the novel species, for which the name Nocardioides ginsengisegetis sp. nov. is proposed, with the type strain Gsoil 485T (KACC 14269T =KCTC 19469T =DSM 21349T).

Abstract: Biodiversity of yeasts was investigated in the ginseng cultivation field. Among 34 isolates tested in this study, 26 isolates belonged to the hymenomycetous yeast group. These 26 strains were classified into 12 species including four new-species candidates that did not have clear affiliation to any established species. Seven isolates among the remaining strains were classified into three ascomycetous yeast species, and one isolate was identified as a urediniomycetous yeast species.

Abstract: More than seventy strains of aerobic bacteria showing [beta]-glucosidase activity were isolated from a ginseng field, using a newly designed Esculin-R2A agar, and identified by their 16S rRNA gene sequences. Of these microorganisms, twelve strains could convert the major ginsenoside, Rb1, to the pharmaceutically active minor ginsenoside Rd. Three strains, Burkholderia pyrrocinia GP16, Bacillus megaterium GP27 and Sphingomonas echinoides GP50, were phylogenetically studied, and observed to be most potent at converting ginsenoside Rb1 almost completely within 48 h, as shown by TLC and HPLC analyses.
