Page(s) : 147-53 Published in: 1998 Actinomycetes are prevalent in oasis palm-grove soils in the Algerian Sahara. These often rare bacteria are well known for their antibiotic-producing potential. They are found in the soil surface horizons, and also at depths of more than 2 m in high quantity. Very diversified species are present in the surface horizon, whereas each deeper horizon is characterized by a particular species. Overall, 727 very well known to rare strains have been isolated and classified into 25 genera, including 132 species. Some of these strains secrete active molecules and preliminary studies indicate that some could be original molecules. This highlights that Saharan oasis soils have considerable resources that have not yet been tapped, especially in the field of antibiotics, which could be produced to stall bacterial and fungal diseases that have been spreading in recent years.
