ISOLATION AND IDENTIFICATION OF CHROMOGENIC BACTERIA FROM VARIOUS SOURCES.
M. T. Rokade* and Dr. A. S. Pethe
Pigments are molecule that have colour. Some bacteria produce pigment as part of their normal metabolism including black, white, brown, golden, silver, florescent green, yellow or blue. The specific colour of the pigment is characteristic for bacterium, pigmented bacteria will form cultures that exhibited some colour. They display all colors from rainbows. The microorganisms such as Pseudomonas aeruginosa, Staphylococcus aureus, Serratia marcenscens, Sarcina maxima, Micrococcus luteus, Micrococcus roseus, etc. produce large number of pigments and they were isolated from various sources. An ideal pigment producing microorganisms should be capable of using a wide range of Carbon and Nitrogen source, have tolerance to pH, temperature and minerals and give reasonable color yield
Keywords: Chromogenic bacteria, Bacterial pigment.
