Neuroprotective potential of new chromones isolated from the soil actinomycete sp. TBRC6027.

Nine new chromone analogs (-) were isolated from the soil actinomycete sp. TBRC6027. The chemical structures were determined based upon NMR spectroscopic methods.

Jiangella endophytica sp. nov., an endophytic actinomycete isolated from the rhizome of Kaempferia elegans.

An endophytic actinobacterium, designated strain KE2-3, was isolated from surface-sterilised rhizome of Kaempferia elegans. The polyphasic approach was used for evaluating the taxonomic position of this strain. The taxonomic affiliation of this strain at genus level could be confirmed by its chemotaxonomic characteristic, i.

Herbidospora soli sp. nov., isolated from soil.

A novel actinomycete strain PS42-9, which formed short chains of spores borne on the tip of long sporophores arising from the substrate mycelium, was isolated from soil in Phu-Sang National Park, Phayao province, Thailand. The isolate contained meso-diaminopimelic acid in the cell-wall peptidoglycan. The whole-cell sugars of strain PS42-9 were glucose, madurose, mannose, rhamnose and ribose.

Nonomuraea stahlianthi sp. nov., an endophytic actinomycete isolated from the stem of Stahlianthus campanulatus.

A novel endophytic actinomycete, designated strain SC1-1T, was isolated from sterilized stem tissue from Stahlianthus campanulatus collected in Udon Thani province, Thailand. The isolate formed short chains of spores on aerial mycelium and presented meso-diaminopimelic acid in the cell wall peptidoglycan. Glucose, madurose, mannose, rhamnose and ribose were observed as sugars in the cells.

Phytohabitans kaempferiae sp. nov., an endophytic actinomycete isolated from the leaf of Kaempferia larsenii.

A novel endophytic actinomycete, designated strain KK1-3T, which formed single spores and long chains of spores (more than 10 spores) was isolated from surface-sterilized Kaempferia larsenii leaf collected from Ubon Ratchathani province, Thailand. The isolate contained l-lysine, meso-diaminopimelic acid and hydroxyl diaminopimelic acid in the cell-wall peptidoglycan. The whole-cell sugars included glucose, mannose, rhamnose, ribose, galactose and xylose.

sp. nov., an endophytic actinomycete isolated from the rhizome of .

A novel Gram-stain-positive, non-motile, endophytic actinomycete, designated strain BR3-1, which produced spore chains borne on the tips of short sporophores, was isolated from the rhizome of collected from Udon Thani province, Thailand. This strain was investigated for its taxonomic position using a polyphasic approach. The strain contained 3-hydroxydiaminopimelic acid and -diaminopimelic acid in the cell-wall peptidoglycan.

Planobispora takensis sp. nov., isolated from soil.

A novel Gram-stain-positive, filamentous bacterial strain (A-T 7458(T)) was isolated from soil collected from hill evergreen forest in Thailand. The strain developed cylindrical sporangia containing a longitudinal pair of motile spores, on short ramifications of aerial mycelia. From a taxonomic study using a polyphasic approach, strain A-T 7458(T) had typical characteristics of members of the genus Planobispora.
