Gentamicin is a water-soluble aminoglycoside antibiotic derived from Micromonospora
purpurea, and actinomycete.
(24) These isolates belong to genera Streptomyces, Micromonospora
, Actinomadura, Saccharomonospora, and Thermoactinomyces.
El-Gendy, Keratinolytic activity from new recombinant fusant AYA2000, derived from endophytic Micromonospora
Thiocoraline bioactive compound isolated from Micromonospora
marina, has shown selective cytotoxicity against lung and colon cancer cell lines as well as melanoma (10).
, Actinomycetes endophyte isolated from the root surface sterilized from 28 plant species from northwest Italy and the most of the result of isolation process is Streptoverticillium, Nocardia, Micromonospora
, and Streptosporangium.
Representative genera are Streptomyces and Micromonospora
Among actinomycetes, Streptomycetes were common in guano and Micromonospora
 on different rhizospheric soils and showed that, among fifty-four isolates of actinomycetes collected, 42 strains were classified as Streptomyces, 4 strains were classified as Micromonospora
, 1 was classified strain as Pseudonocardia, 1 strain was classified as Actinomadura, 1 was classified strain as Nocardia, and 5 strains were classified as non-Streptomyces.
The rhizosphere of Chakwal-50 possessed genera includes: Arthrobacter Modestobacter Aciditerrimonas Streptomyces Conexibacter Nocardioides Micromonospora
Ilumatobacter and Dactylosporangium.
Both of cluster I and cluster II were separated from outgroup cluster (Micromonospora
Of the 87 isolates, 59.8% (n = 52) of the isolates were assigned as genus Streptomyces, 14.9% (n = 13) as the genus Mycobacterium, and the remaining isolates as Leifsonia (n = 6), Microbacterium (n = 4), Sinomonas (n = 4), Nocardia (n = 2), Terrabacter (n = 2), Gordonia (n = 1), Micromonospora
(n = 1), Nocardioides (n = 1), and Streptacidiphilus (n = 1).
