sp. nov., sp. nov. and sp. nov., endophytic actinobacteria isolated from wild orchid ( Roxb).

Three novel mycelium-forming actinobacteria, designated OC33-EN06, OC33-EN07, and OC33-EN08, were isolated from wild orchid ( Roxb), collected from a hill evergreen forest in Northern Thailand. Strains OC33-EN06 and OC33-EN07 showed the highest 16S rRNA gene similarity with TT00-04, 99.17 and 99.

sp. nov., isolated from a yellow-ringed grass moth ().

A novel mycelium-forming actinomycete strain, designated A-F 0318, was isolated from a yellow-ringed grass moth () collected from Phitsanulok Province, Thailand. Long chains of non-motile cylindrical spores with a smooth surface developed on aerial mycelia. The polyphasic taxonomic study suggested that strain A-F 0318 belonged to the genus .

sp. nov., isolated from cave rock.

A novel actinomycete, designated strain ASG 168, was isolated from cave rock collected from Stegodon Sea Cave in Thailand. Long chains of non-motile spores that were oval or spherical in shape with a smooth surface developed on aerial mycelia. Substrate mycelia fragmented into irregular rod-shaped elements.

sp. nov., isolated from humic soil on bird's nest fern ( L.).

A novel member of the actinobacteria, designated strain A-T 0013, was isolated from humic soil on a bird's nest fern ( L.) collected from Khao Yai National Park in Thailand. According the results of a polyphasic taxonomic study, A-T 0013 had characteristics typical of members of the genus .

sp. nov., isolated from plant litter.

A novel zoosporic actinomycete, designated strain A-T 5661, was isolated from plant litter collected in Thailand. Strain A-T 5661 developed large multilocular sporangia containing motile sporangiospores at the ends of sporangiophores on substrate mycelium. The results of our polyphasic taxonomic study demonstrated that the strain had characteristics typical of members of the genus .

Verrucosispora endophytica sp. nov., isolated from the root of wild orchid (Grosourdya appendiculata (Blume) Rchb.f.).

A novel endophytic filamentous bacterium strain A-T 7972, was isolated from wild orchid Grosourdya appendiculata (Blume) Rchb.f. collected in Thailand.
