ABSTRACT
Twenty nine actinomycetes isolates randomly selected of 130 from Burullos Lake were
investigated. These isolates were characterized taxonomically for 63 phenotypic characters
including morphological; biochemical, nutritional, substrate utilization and anti-microbial
analyses. The results were analyzed by numerical techniques using the simple matching
coefficient (SSM) and unweighted pair group average linkage (UPGMA) clustering. At
54% similarity level, the majority of actinomycetes strains were grouped into six phena (A,
B, C, D, E and F) only two strains were grouped separately and formed two single clusters
at this level. A representative strain from each phenon was chosen, they were identified as
Streptoverticillum morookaense, Nocardia brasiliensis, Streptomyces alanosinicus,
Streptomyces globosus and Streptomyces gancidicus
