Abstract

A total of 268 strains of Actinomycetes were isolated from soil and leaf-litter samples collected in Jambi (Sumatera) and Cibinong (West Java) using three selective isolation methods. All the isolates were identified by morphological characteristic and by analysis of 16S rDNA sequence. On the basis of their morphology and 16S rDNA sequence, 164 isolates were belonged to the Streptomyces Group and 104 isolates were belonged to the Rare-Actinomycetes (Non-Streptomyces) Group. Furthermore, 40% of isolates in Streptomyces Group and 62% of isolates in Non-Streptomyces Group are supposed to be new taxa. It is indicated the richness of Actinomycetes in these two area. The genus Streptomyces is the most abundant in soil samples, occupying 60- 75% of all isolates; while the genus Actinoplanes is mainly found in leaf-litter samples (70%). The use of selective isolation media is important to elucidate the microbial diversity.Key words: Actinomycetes, microbial diversity

Abstract

A total of 29 actinomycetes strains were isolated and identified by full sequence analysis of the 16S rRNA gene. Samples were collected from Bali Island, Indonesia, including 18 soil and 20 leaf litter samples from Eka Karya Botanical Garden. Two isolation methods were used in this study: SDS-extract (SY) and Rehydration-Centrifugation (RC). Based on 16S rRNA gene analysis, the isolated actinomycetes were grouped into two genera. Molecular analysis of 16S rRNA gene similarities showed that the actinomycetes isolated from Eka Karya Botanical Garden were of diverse origin. Analysis of soil samples resulted in 144 isolates belonging to 24 genera and more than 87 species, with Streptomyces being the dominant genus. This was followed by Actinoplanes (25 isolates, 17%). From leaf litter samples, 85 isolates were obtained, belonging to 9 genera and more than 41 species. The most dominant genus was Catenuloplanes (42 isolates, 49%), followed by Actinoplanes (16 isolates, 19%).
