Abstract : Pigments are the chemical compounds which has diverse applications in several industries. Recently, much attention is paid in the consumption of pigments in pharmaceutical and cosmetic industries, as well as food dyes stuff. The aim of the present study was to isolate the microorganisms from Jeddah, capable of producing pigments with anti-microbial activity. Soil samples were collected from different areas of Jeddah, Saudi Arabia. The pigment producing bacteria were selected based on the color they produced in nutrient agar plant. The selected strains were identified using Biochemical and Molecular technique. The one which produce blue color and has a promising antibacterial activity was identified as Pseudomonas aeruginosa. This strain was introducing for UV spectrophotometer and GC-MS analysis. The one which produced red color was identified as Serratia marcescens and orange pigment producing was identified as Pontibacter mucosus. Results show that among the color producing bacteria only Pseudomonas aeruginosa pigment has a promising antibacterial activity. The pigment has a 13 mm zone of inhibition against Staphylococcus aureus (MRSA) and has about 9 mm zone of inhibition against E. coli O157:H7. It is concluded that this pigment can be used as food colorant, flavoring agent, dying agents and they are widely applied in medicinal aspects.
