According to the previous study, a Gram-stain-negative, rodshaped, non-spore-forming, non-motile bacterium, Novosphingobium ginsenosidimutans FW-6 T was isolated from fresh water. Strain FW-6 T possessed β-glucosidase activity, which was responsible for its ability to convert ginsenoside Rb1 to ginsenoside Rd. In this study the whole genome of Novosphingobium ginsenosidimutans FW-6 T was sequenced, which consisted of one circular chromosome of 3,118,872 bp, with a DNA G + C content of 64.3%. Of the 3,073 predicted genes, 2,996 proteincoding genes, 50 RNA genes and 27 pseudogenes were identified. The whole genome analysis of strain FW-6 T showed several genes including glycoside hydrolase, antitoxin genes, and DNA repair genes.

Pseudobacter ginsenosidimutans Gsoil 221 T was isolated from the soil of a ginseng field. The strain Gsoil 221 T converted the ginsenosides, Rb1 and Rc (two dominant active components of ginseng) into ginsenoside F2. The whole genome sequence of Pseudobacter ginsenosidimutans Gsoil 221 T consisted of one circular chromosome comprised of 7,797,595 bp, with a DNA G + C content of 46.9%. Of the 6,115 predicted genes, 5,941 protein-coding genes, 57 RNA genes, 117 pseudogenes and 1 CRISPR array were identified. A whole genome analysis of strain Gsoil 221 T showed glycoside hydrolase genes, DNA mismatch repair genes, and antitoxin system genes.

A Gram-positive, rod-shaped, ivory colored, and motile, Lactobacillus koreensis 26-25 was isolated from Korean kimchi. Strain 26-25 showed the ability of conversion from major ginsenosides into minor ginsenosides for which whole genome was sequenced. The whole genome sequence of Lactobacillus koreensis 26-25 consisted of one circular chromosome comprised of 3,006,812 bp, with a DNA G + C content of 49.23%. The whole genome analysis of strain 26-25 showed many glycosides hydrolase genes, which may contribute to identify the genes responsible for transformation of major ginsenosides into minor ginsenosides for its high pharmacological effects. 김치로부터 분리한 Lactobacillus koreensis 26-25 균주의 유전체서열을 분석하였다. 균주 26-25의 유전체는 G + C 비율이 49.23%이며, 2,720개의 유전자와 2,556개의 단백질 코딩 유전자, 85개의 위유전자 그리고 78개의 RNA 유전자를 포함한 단일 원형 염색체로 구성되었으면 그 크기는 3,006,812 bp였다. 균주 26-25는 인삼사포닌의 당 분해에 관여하는 여러 타입의 글라이코시다제 유전자를 가지고 있었다. 이러한 지놈 분석은 주요 진세노사이드가 우수한 약리학적 활성의 미량 진세노사이드로 전환하는데 관여하는 유전자 특징을 이해하는데 큰 기여가 되었다.

퇴비로부터 분리한 Niabella ginsenosidivorans $BS26^T$ 균주의 유전체서열을 분석하였다. 균주 $BS26^T$의 유전체는 G + C 비율이 44.48%이며, 4,800개의 유전자와 4,704개의 단백질 코딩 유전자, 85개의 위유전자 그리고49개의 RNA유전자를 포함한 단일 원형 염색체로 구성되었으면 그 크기는 5,627,734 bp였다. 균주 $BS26^T$는 인삼사포닌의 당 분해에 관여하는 여러 타입의 글라이코시다제 유전자를 가지고 있었다. 이러한 유전체 분석은 주요 진세노사이드 전환에 관여하는 유전자 특징을 이해하는데 큰 기여가 되었다. An orange-colored, rod-shaped strain, designated Niabella ginsenosidivorans $BS26^T$, was isolated from compost. Strain $BS26^T$ showed the ability to convert major ginsenosides to minor ginsenosides, and its whole genome was sequenced. The whole genome of N. ginsenosidivorans $BS26^T$ consists of a single circular chromosome of 5,627,734 bp with 44.48% G + C content. Based on the complete genome sequence of strain $BS26^T$, we found several glycosides hydrolase-encoding genes that might involve in the conversion of major ginsenosides into minor ginsenoside and deliberate its strong pharmacological effects.
