In one or the various other way your life on earth depends on pigments just like how crops prepare their particular food with chlorophyll and oxygen taken in the body with hemoglobin (Britton, 1995).

Due to their noticeable hazards some synthetic chemical dyes have even been taken from external use for example , benzidine inorganic dyes cause bowel cancer, while carbon dark (widely used as printing ink pigment) is thought to be a potential carcinogen.
The unethical discharge of untreated industrial dye effluents produce toxins and persevere for number of years due to long periods of stability (Babitha, 2009). Thus these drawbacks of synthetic color have improved the global demand for natural colors (Manikprabhu and Lingappa, 2013 The main sources for organic pigments are plants or microorganisms, nevertheless the plant colors has many drawbacks such as non-availability throughout the year and pigment steadiness, solubility and enormous scale flower use may lead to loss of important species. For this reason reason another readily available all-natural sources to get pigments happen to be microorganisms like fungi and bacteria(Arulselvi ainsi que al., 2014).
