Amycolatopsis acididurans sp. nov., isolated from peat swamp forest soil in Thailand.

A polyphasic approach was used to describe strain K13G38, a novel actinomycete isolated from peat swamp forest soil collected from Surat Thani Province, Thailand. The 16S rRNA gene phylogenetic analysis indicated that the strain belonged to the genus Amycolatopsis and showed the highest sequence similarities to both Amycolatopsis acidiphila JCM 30562 and Amycolatopsis bartoniae DSM 45807 (96.8% sequence similarity).

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).

sp. nov., an actinomycete isolated from cave soil in Thailand.

A novel actinobacterium, designated strain NN258, was isolated from a cave soil sample collected from a karst cave at Khao No-Khao Kaeo, Nakhon Sawan province, Thailand. The morphological, chemotaxonomic and phylogenetic characteristics were consistent with its classification in the genus . Strain NN258 showed the highest 16S rRNA gene sequence similarity values to HMC10, 6K102, DSM 43768, KC712 and IFO 14681.

Streptomyces acidicola sp. nov., isolated from a peat swamp forest in Thailand.

A novel actinobacterium, designated strain K1PN6, was isolated from soil sample collected in Kantulee peat swamp forest, Surat Thani province, Thailand. The morphological, chemotaxonomic, and phylogenetic characteristics were consistent with its classification in the genus Streptomyces. Based on 16S rRNA gene sequence analysis, strain K1PN6 showed highest similarity to Streptomyces phyllanthi PA1-07 (98.

Gordonia oryzae sp. nov., isolated from rice plant stems (Oryza sativa L.).

A novel endophytic actinomycete, designated strain RS15-1S, was isolated from surface-sterilized stems of Oryza sativa L. collected from Sisaket province, Thailand. The colony of strain was strong orange, catalase-positive and oxidase-negative.

Nonomuraea suaedae sp. nov., isolated from rhizosphere soil of Suaeda maritima (L.) Dumort.

A polyphasic approach was used to identify the novel actinomycete, strain 10-20SHSu, isolated from the rhizosphere of the mangrove associated plants Suaeda maritima collected from Phetchaburi Province, Thailand. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the organism belonged to the phylogenetic cluster of the genus Nonomuraea and was most closely related to Nonomuraea soli YIM 120770 (98.1% sequence similarity), Nonomuraea endophytica YIM 65601 (97.

Quadrisphaera oryzae sp. nov., an endophytic actinomycete isolated from leaves of rice plant (Oryza sativa L.).

A novel endophytic actinobacterium, designated strain RL12-1S, was isolated from surface-sterilized leaves of Oryza sativa L. collected from Roi Et province, Thailand. Taxonomic position of strain RL12-1S was studied using the polyphasic approach.
