A Gram-negative, rod-shaped bacterial strain, YC6729(T), was isolated from vermicompost collected at Masan, Korea, and its taxonomic position was investigated by a polyphasic taxonomic approach. Strain YC6729(T) grew optimally at 30 °C and at pH 6.5-8.5. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain YC6729(T) belongs to the(More)
A Gram-staining-positive, coccoid to rod-shaped bacterium, designated strain YC6903(T), was isolated from a halophytic plant (Carex scabrifolia Steud.) collected from sand dunes at Namhae Island, Korea, and its taxonomic position was investigated by using a polyphasic approach. Strain YC6903(T) grew optimally at 30 °C and at pH 8.0. Phylogenetic analysis(More)
Using two forest soils, we previously constructed two fosmid libraries containing 113,700 members in total. The libraries were screened to select active antifungal clones using Saccharomyces cerevisiae as a target fungus. One clone from the Yuseong pine tree rhizosphere soil library, pEAF66, showed S. cerevisiae growth inhibition. Despite an intensive(More)
A microbial community analysis of forest soil from Jindong Valley, Korea, revealed that the most abundant rRNA genes were related to Acidobacteria, a major taxon with few cultured representatives. To access the microbial genetic resources of this forest soil, metagenomic libraries were constructed in fosmids, with an average DNA insert size of more than 35(More)
A novel bacterial strain, YC7001(T), was isolated from the rhizosphere soil of rice collected at Jinju, Korea, and was characterized using a polyphasic approach. Cells of strain YC7001(T) were Gram-negative-staining, yellow-pigmented, rod-shaped, aerobic, heterotrophic and non-motile. Strain YC7001(T) grew optimally at 25-30 °C, pH 5.0-8.0 and degraded(More)
During a study of endophytic bacteria from coastal dune plants, a bacterial strain, designated YC6881(T), was isolated from the root of Rosa rugosa collected from the coastal dune areas of Namhae Island, Korea. The bacterium was found to be Gram-staining-negative, motile, halophilic and heterotrophic with a single polar flagellum. Strain YC6881(T) grew at(More)
Two Gram-reaction-negative, yellow-orange-pigmented, rod-shaped bacterial strains, designated YC6722(T) and YC6723(T), were isolated from rhizosphere soil samples collected from rice fields in Jinju, Korea. Strains YC6722(T) and YC6723(T) grew optimally at 25-30 °C and at pH 7.0-8.5. Phylogenetic analyses of 16S rRNA gene sequences showed that strain(More)
A Gram-stain-negative, coccobacilli-shaped bacterium, designated YC6724T, was isolated from the rhizosphere of rice in Jinju, Korea. The taxonomy of strain YC6724T was studied using a polyphasic approach. Strain YC6724T grew optimally at 30 °C and pH 7.0-8.0. Comparative 16S rRNA gene sequence analyses showed that the strain was most closely related to(More)
A metagenome is a unique resource to search for novel microbial enzymes from the unculturable microorganisms in soil. A forest soil metagenomic library using a fosmid and soil microbial DNA from Gwangneung forest, Korea, was constructed in Escherichia coli and screened to select lipolytic genes. A total of seven unique lipolytic clones were selected by(More)
A Gram-negative, non-spore-forming, endophytic bacterium, strain YC6886(T), was isolated from the root of a halophyte, Rosa rugosa, which inhabits coastal areas of Namhae Island off the southern coast of Korea. Cells were non-motile, obligately aerobic rods and formed pale-yellow colonies. The isolate grew at 4-32 °C (optimum 25-28 °C) and at pH 6.5-9.5(More)
