Abstract
The purpose of this study was to investigate streptomycete populations in desert and savanna ecozones in Sudan and to identify species based on 16S rRNA gene sequences. A total of 49 different
phenotypes (22 from sites representing the desert and semi-desert ecozone; 27 representing the savanna ecozone) have been included in the study. The isolates were characterized phenotypically and confirmed using 16S rRNA gene sequence analysis. The two ecozones showed both similarities and uniqueness in the types of isolates. The shared species were in cluster 1 (
, cluster 2 (
sp.), cluster 3 (
-like), and cluster 7 (
. The desert ecozone revealed unique species in cluster 9 (
sp.) and cluster 10 (
). Whereas, the savanna ecozone revealed unique species in cluster 4 (
sp.), cluster 5 (
), cluster 6 (
), and cluster 8 (
sp.). Streptomycetes are widely distributed in both desert and the savanna ecozones and many of these require full descriptions. Extending knowledge on
communities and their dynamics in different ecological zones and their potential antibiotic production is needed.
