Among the bacteria, a mycelial growth habit is common only among the actinomycetes , a diverse group of Gram-positive eubacteria. Some of these organisms, termed sporoactinomycetes or euactinomycetes , develop only in the mycelial state, and they reproduce through the formation of unicellular ...
Actinobacteria are Gram-positive, aerobic or facultative, spore-forming bacteria belonging to the order Actinomycetales, characterized by high guanine and cytosine (G + C) content (>55 mol %) in DNAs and rod-shape or mycelium like filamentous structures. The name “Actinomycetes” was derived ...

primary screening by perpendicular streak method against Gram-positive (Bacillus subtilis, B. cereus, B. megaterium, B. coagulase and Staphylococcus aureus) and Gram-negative (Escherichia coli, Klebsiella pneumonia, Pseudomonas putida, Proteus vulgaris, Salmonella typhi and Shigella sonnei) test bacteria...
Actinomycetes are Gram-positive soil bacteria that produce pharmaceutically important natural products as secondary metabolites1. Each strain contains more than 30 putative biosynthetic gene clusters for secondary metabolites2,3. Although they are considered to have potential for producing more than 30 secon...

Biologically active secondary metabolites from Actinomycetes secondary metabolites demonstrate activity against Gram-positive bacteria and some fungi [33].3. Antimicrobial properties of novel antibioticsAt present, antibacterial activity of secondary metabolites is of high interest. It is triggered by the exte...

[3,4,5]. Actinobacteria are Gram-positive filamentous bacteria containing a high G+C content. They generally produce mycelium and reproduce by sporulation similar to filamentous fungi. However, they possess prokaryotic nucleoid and peptidoglycan cell wall significantly different from fungi [6]. Hence,...
