Preliminary Characterization of Yeasts and Actinomycetes Isolated from Mammalian Feces

ABSTRACTYeasts and actinomycetes isolated from fecal pellets of various mammals from a zoo in Sofia, Bulgaria were identified using DNA barcoding analysis. The analysis has shown that yeast strains belong to the ascomycete genera Kluyveromyces, Clavispora, Pichia, Wickerhamomyces, Candida, Zygowilliopsis, Galactomyces, Hanseniaspora, and Debaryomyces. Basidiomycete yeasts belong to the genera Trichosporon, Cryptococcus, Rhodotorula and Guehomyces. All actinomycete strains were identified as Thermoactinomyces saccharii. Additionally, extracellular enzymatic activity and ability to grow at various temperatures of isolated strains were analyzed.
