Abstract
From the aqueous solution of a soluble pigment, removal of the soluble pigment is attained by intimately mixing the aqueous solution, in the presence of an inorganic salt, with the product of microorganic culture obtained by culturing a bacterium belonging to genus Rhodococcus and allowing the resultant mixture to stand at rest thereby causing the pigment to flocculate and precipitate therein.
