Diversity and bioactivities of cultured actinomycete isolated from animal feces and Xylocopa dissimilis

Abstract:

Abstract: [Objective] To study the diversity and bioactivities of cultured actinomycete from feces of Ailuropoda melanoleuca, Equus burchelli and Rhizomys sinensis, and Xylocopa dissimilis body. [Methods] Fresh feces samples of animals’ and Xylocopa dissimilis were collected. We used four media to isolate the actinomycete. Strains were identified by phylogenetic analysis of 16S rRNA gene sequences. Hydrolization and enzyme activities of isolates were examined. [Results] Actinomycetes (121) from the samples were isolated on four media. Among them 47 strains belonged to 9 actinomycetes genera. Six known rare genera and one possible new genus of actinomyctes from Rhizomys sinensis were identified. Three possible new species from other three samples were identified. Some strains could hydrolyze chicken feather and cellulose. [Conclusion] It is considered that the coprophilous microorganisms not only have important function on the digestion and absorption of animal feed, but also are important resource for development of industrial products, including enzyme and bioactive metabolites.
