The bacterium capable of producing melanin pigment in the presence of L-tyrosine was isolated from crop field soil sample and identified as Klebsiella sp. GSK based on morphological, biochemical and 16S rDNA sequencing. The polymerization of this pigment occurs outside the cell wall, which has granular structure as melanin ghosts. The chemical characterization of pigment particles showed acid resistant, alkali soluble, insoluble in most of the organic solvents and water. The pigment gets… CONTINUE READING
