Resumo: | A total of 2152 Actinobacteria strains were isolated from native Cerrado (Brazilian Savannah) soils located in Passos, Lumin ́arias, and Arcos municipalities (Minas Gerais State, Brazil).The soils were characterised for chemical and microbiological analysis.The microbial analysis led to the identification of nine genera Streptomyces, Arthrobacter, Rhodococcus, Amycolatopsis,Microbacterium, Frankia, Leifsonia, Nakamurella, and Kitasatospora) and 92 distinct species in both seasons studied (rainy and dry). The rainy season produced a high microbial population of all the aforementioned genera.The pH values of the soil samples from the Passos, Lumin ́arias, and Arcos regions varied from 4.1 to 5.5. There were no significant differences in the concentrations of phosphorus, magnesium, and organic matter in the soils among the studied areas. Samples from the Arcos area contained large amounts of aluminium in the rainy season and both hydrogen and aluminium in the rainy and dry seasons. The Actinobacteria population seemed to be unaffected by the high levels of aluminium in the soil. Studies are being conducted to produce bioactive compounds fromActinobacteria fermentations on different substrates.Thepresent data suggest that the number and diversity of Actinobacteria spp. in tropical soils represent a vast unexplored resource for the biotechnology of bioactives production. |
