A rod-shaped Gram-staining-negative, non-motile, aerobic and fucoidan-digesting strain, designated TC2(T), was isolated from marine algae collected from the coast of the Sea of Okhotsk at Abashiri, Hokkaido, Japan. The bacterium formed yellow, translucent, circular and convex colonies. Comparative 16S rRNA gene sequence analysis indicated that the strain(More)
Strains of aerobic, Gram-positive, rod-shaped, round-spore-forming bacteria were isolated from different geographical locations and a subsequent polyphasic study was undertaken to clarify the taxonomic position of the round-spore-forming isolates strain KSC-SF6g(T), strain M32 and strain NBRC 12622. 16S rRNA gene sequence similarities demonstrated that(More)
Phylogenetic relationships of the species belonging to the genus Myxococcus were elucidated based on the sequences of 16S rRNA genes and 16S-23S rRNA gene internal transcribed spacer (ITS) regions. The Myxococcus species were consequently classified into four distinct groups. The type strain of Myxococcus coralloides occupied an independent position (Group(More)
Twenty-one homofermentative lactic acid bacteria were isolated from fermented cummingcordia (pobuzihi), a traditional food in Taiwan. The isolates had identical 16S rRNA gene sequences that were distinct from those of other lactobacilli, and their closest neighbours in the 16S rRNA gene sequence phylogenetic tree were strains of Lactobacillus acidipiscis.(More)
Twenty-five Bacillus strains capable of producing gamma-polyglutamic acid (PGA) were isolated from fermented locust bean products manufactured in the savanna area of Ghana. To clarify the phylogeny of these PGA-producing strains, phylogenetic analyses based on sequences of 16S rDNA, rpoB (RNA polymerase beta-subunit) and fus (elongation factor G) genes were(More)
Natto-like fermented soybean products are manufactured and consumed in many Asian countries. In this study, we isolated thirty-four Bacillus strains capable of producing gamma-polyglutamic acid (PGA) from natto in mountainous areas of South Asia and Southeast Asia and from soils in Japan. To elucidate the phylogeny of these PGA-producing strains,(More)
A Gram-stain-positive, lactic acid-producing bacterium designed strain MK21-7T, was isolated from tree bark collected from the north east of Thailand. This strain was a facultatively anaerobic spore-forming rod that was catalase-negative. It contained meso-diaminopimelic acid in the cell wall peptidoglycan and had seven isoprene units (MK-7) as the(More)
A Gram-stain-positive, lactic acid bacterium, strain Ru20-1T, was isolated from a flower (West-Indian jasmine) collected from Kalasin province, Thailand. A polyphasic approach was used to determine the taxonomic position of this strain. Studies of morphological and biochemical characteristics revealed that strain Ru20-1T belonged to the genus Lactobacillus.(More)
Three Lactobacillus-like strains, NB53T, NB446T and NB702, were isolated from traditional fermented food in Thailand. Comparative 16S rRNA gene sequence analysis indicated that these strains belong to the Lactobacillus plantarum group. Phylogenetic analysis based on the dnaK, rpoA, pheS and recA gene sequences indicated that these three strains were(More)
