ABSTRACT

In this study, twelve isolates of actinomycetes were segregated from different habitats like dams, mountains and caves of Hadhramout, Yemen on different media, such as starch casein agar, glycerol asparagine agar, tyrosine agar, yeast extract- malt extract agar, glycerol yeast extract agar and starch yeast extract agar for exploring their ability to produce diffusible pigments. Most of the isolates produced pigments, which means that these actinomycetes could have commercial values and open doors for food colors and beverages, in the pharmaceutical industries, and also in cosmetic industries. The same isolates of actinomycetes, when grown on different media also gave different colors. This indicates that actinomycetes have the ability to produce different pigments when culture media are changed.
