Abstract

Some Actinomycetes isolated from Waigeo Raja Ampat Regency Papua have been identified. Those isolates were also characterized for their cellulolitic and phosphate solubilizing ability. Microscopic identification was based on Miyadoh (1997) and Holt (1994) methods.Actinomycetes could be identified by microscopic observation on spores, chain spore, hypha, aerial hypha and its pigmentation.The cellulolitic ability was observed by clear zone ratio in CMC medium and phosphate solubilizing activity by the same approach in Vikoskaya medium.From 139 Waigeos Actinomycetes isolates which had been deposited in LIPI Microbial Collection (LIPIMC) were identified as 10 genera (Actinomadura, Actinoplanes, Microbiospora, Micromonospora, Nocardia, Pseudonocardia, Saccharopolispora, Streptomices, Streptosporangium and Thermomonospora). As much as 57.5% phosphate solubilizing actinomycetes and 82.7 % cellulolitic actinomycetes were detected.

Abstract

A total of 344 isolates of actinomycetes were isolated from leaf litter and soil samples collected from four locations of Enggano Island, Bengkulu. eighty eight isolates were selected using morphological characteristics and identified using 16S rRNA gene sequence analysis. Three families (Micromonosporacea, Streptomycetaceae, and Streptosporangiaceae) and eight genera were found from these samples. Approximately 80% of these strains belonged to Streptomyces group and 20% of isolates were similar to rare actinomycetes. Based on homology search (BLAST) and phylogenetic tree analysis, isolates of rare actinomycetes (EgA15, EgA30, EgA85, EgA386, EgA236, EgA243, EgA335, EgA112, EgA41,EgA312, EgA314) were identified as Kitasatosporia paracochleata (100%), Kitasatospora azatica (99%), Kitasatospora griseola (99%), Sphaerisporangium album (99%), Actinoplanes nipponensis (99%), Pseudosporangium ferrugineum (99%), Nonomuraea rosela (99%), Nonomuraea guangzhouensis (98%), Micromonospora chaiyaphumensis (99%),Micromonospora chaiyaphumensis (99%), and Couchioplanes caeruleus (99%) respectively.
