Isolation and Characterization of Pigment Producing Bacteria From Water and Study of Antimicrobial Activity of Pigments

Subi Mathew

The aim of the present study was to isolate the microorganisms from water, capable of producing pigments. Pigment producing bacterium strain isolated from water is characterized for morphological, physiological and biochemical parameters were identified staining tests, Motility tests, Biochemical tests, Sugar fermentation tests. The isolated strain produced yellow, orange, light yellow and violet pigment on plate count agar medium. The pigments were extracted from the bacterial cultures and their antimicrobial activity was noted against human pathogens. The extracted pigments had inhibitory effect on both Gram positive and Gram negative bacteria. Select the violet pigment producing bacteria and the optimum growth conditions were done by growing it on in different incubation Temperature, pH, carbon source and nitrogen sources. As an application, Yellow and Violet pigment producing bacteria produced pigment was used as a colouring agent in acrylic paints.
