sp. nov., a polyene producer, and sp. nov., two novel actinobacterial species from peat swamp forests in Thailand.

Two novel actinobacterial strains, designated RB6PN23 and K1PA1, were isolated from peat swamp soil samples in Thailand and characterized using a polyphasic taxonomic approach. The strains were filamentous Gram-stain-positive bacteria containing -diaminopimelic acid in their whole-cell hydrolysates. Phylogenetic analysis of their 16S rRNA gene sequences revealed that strain RB6PN23 was most closely related to (99.

Saccharopolyspora oryzae sp. nov., isolated from rhizosphere soil of the wild rice species Oryza rufipogon.

A novel actinobacterium, designated as strain WRP15-2, was isolated from rhizosphere soil of rice plant (Oryza rufipogon). The strain was Gram-stain-positive, aerobic, and non-motile. Phylogenetic analysis based on the 16S rRNA gene sequences showed that strain WRP15-2 fell into the genus Saccharopolyspora.

sp. nov., a novel actinobacterium isolated from peat swamp forest soil in Thailand.

A polyphasic approach was used to describe strain RB6PN25, an actinobacterium isolated from peat swamp forest soil in Rayong Province, Thailand. The strain was a Gram-stain-positive and filamentous bacterium that contained -diaminopimelic acid, mannose and ribose in whole-cell hydrolysates. MK-9(H) was the major menaquinone.

sp. nov., isolated from a tropical peat swamp forest soil, and proposal for the reclassification of as a later heterotypic synonym of .

A polyphasic approach was used to describe strain RB6PN24, a novel actinobacterium isolated from peat swamp forest soil collected from Rayong province, Thailand. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the strain belonged to the genus and showed the highest sequence similarities to IFO 15206 (98.7 %) and MMS16-CNU292 (98.

sp. nov., isolated from peat swamp forest soil.

A novel actinomycete, designated strain KK5PA1, was isolated from a soil sample collected from Kuan Kreng peat swamp forest, Nakhon Si Thammarat Province, Thailand. The morphological, chemotaxonomic and phylogenetic characteristics were consistent with its classification in the genus . Strain KK5PA1 was most closely related to NEAU-HZ10 (98.

sp. nov., a novel actinomycete isolated from peat swamp forest soil.

A novel actinobacterium, designated strain K10HN5, was isolated from a peat soil sample collected from Kantulee peat swamp forest, Surat Thani Province, Thailand and its taxonomic position was determined using a polyphasic approach. Strain K10HN5 contained -diaminopimelic acid, arabinose, galactose, glucose and ribose in its whole-cell hydrolysates. The predominant menaquinone was MK-8(H).
