Screening and Extraction of Microbial Pigment from Organism Isolated from Marine Water

Synthetic colors have been widely used in various industries including food, textile, cosmetic and pharmaceuticals. However toxicity problems caused by synthetic pigments have triggered intense research in natural colors and dyes. Among the natural Sources, pigment producing microorganisms hold a promising potential to meet present day challenges. Furthermore natural colors not only improve the marketability of the product but also add extra features like anti- oxidant, anti- cancer properties etc. In this review, we present various sources of microbial pigments and to explore their biological and clinical properties like antimicrobial, antioxidant, anticancer and anti- inflammatory. The study also emphasizes upon key parameters to improve the bioactivity and production of microbial pigments for their commercial use in pharmacological and medical fields. Water samples were collected from different areas under different climatic conditions. A total of five pigmented colonies were isolated that produced intracellular pigments and isolated organism were characterized by the Bergeys Manual of Determinative Bacteriology. The pigments were extracted from the isolates and their antimicrobial and anti-fungal activity was identified. The extracted pigments had inhibitory effect on both Gram positive and Gram negative bacteria as well on fungus. So it was concluded that water has diverse organisms which showed antibacterial and antifungal activity and also some significant anti-oxidant properties.
