An Efficient Method for Isolation and Separation of Pigments from Streptomyces alboflavus TD-1

摘要

Colorants derived from natural sources, such as plant and microorganisms, are believed to be a good alternative to artificial pigments because they are non-toxic, non-carcinogenic and biodegradable [1, 14]. The isolation and application of microbial pigments have been investigated by various researchers [13]. Urgent problems that need to be solved are improving extraction and separation process of pigment produced by microorganisms expanding the scope of natural pigment application and reducing the production cost of natural pigment [7, 15]. For microbial pigments, their solubility, coloring, and stability are important indices of their applicability in industry [18]. Microbial pigments are also attractive for its wide range of biological activities, including activities as antimalarial, antifungal, immunosuppressant, and antibiotic agents, which make them an excellent target for dual or multifunctional application [8].
