The rhizosphere of Chakwal-50 possessed genera includes: Arthrobacter Modestobacter Aciditerrimonas Streptomyces Conexibacter Nocardioides Micromonospora Ilumatobacter and Dactylosporangium
Some genera of this group are Actinomadura, Actinoalloteichus, Actinoplanes, Amycolatopsis, Actinokineospora, Acrocarpospora, Actinosynnema, Catenuloplanes, Cryptospo -rangium, Dactylosporangium
, Kibdelosporangium, Kineosporia, Kutzneria, Microbispora, Microtetraspora, Nocardia, Nonomuraea, Planomonospora, Planobispora, Pseudonocardia, Saccharomonospora, Saccharopolyspora, Saccharothrix, Salinispora, Streptosporangium, Spirilliplanes, Thermomonospora, Thermobifida, and Virgosporangium .
A team of scientists working in Switzerland has shown how pyridomycin, a natural antibiotic produced by the bacterium Dactylosporangium
The new drug is actually a natural product secreted by a soil bacterium called Dactylosporangium
fulvum and has been found effective against drugresistant forms of tuberculosis as well.
, while environmental sample DNA, genus specific 16S rDNA primers (Streptomyces, Micromonospora, Dactylosporangium, Thermomonospora, and Streptosporangium genera), and amplification conditions were used according to Monciardini et al.
In uncultivable approaches, highest yield of DNA was recovered from surface water than other samples (surface water > 1.5 m > 2.5 m) respectively, followed by the amplification of 16S rDNA using specific primers of Streptomyces, Micromonospora, Streptosporangium, Thermomonospora, and Dactylosporangium of corresponding molecular weight of 0.6, 1.0, 0.5, 0.8, and 0.58 kb, respectively.
