Abstract

Most actinobacteria species is still unknown and in different ecological niches our knowledge about the ecology of these microorganisms is nonexistent. Moreover, bacteria, mainly from Actinobacteria group, are known as excellent bioactive compounds producers for several applications. Therefore, this economical and biotechnological appeal has created high expectations on the discovery of new species of actinomycetes and the possible compounds they may produce. Thus, projects related to taxonomy and systematic of these species are justified by its importance in increasing the knowledge on microbial diversity and, consequently, assist the preservation of National genetic patrimony. Brazil has been recognized as one of the largest areas of biodiversity in the world and "Mata Atlântica" has a considerable participation in this title. Many microbiological studies have been realized in native areas of this forest, however, only few works have focused on identification of bacterial species in restored areas. Besides being an interesting ecological niche for prospection and exploration of actinobacteria species, restored forest fragments are thoroughly neglected in relation to the study of their microbial diversity. In our laboratory, Actinobacteria was isolated from three reforested area at São Paulo State. Some of these isolates were classified as Amycolatopsis and presented low 16S rRNA similarities values with type strains which may likely represent new phyletic nucleus (FAPESP: 11/50243-1 and 12/03363-4). Thus, main aim is enhancing the taxonomic placement of these isolates using a polyphasic approach to circumscribe the putative new species.
