Filamentous bacteria belonging to the order Actinomycetales, especially Micromomospora and Streptomyces strains, have a unique and proven capacity to produce novel antibiotics (Bentley et al., 2002), hence the continued interest in screening such organisms for new bioactive and It is also becoming increasingly clear that un- and under-explored habitats, such as desert biomes and marine ecosystems, are a very rich source of novel actinomycetes which have the capacity to produce interesting new bioactive compounds, including antibiotics (Hong et al., 2009).
