By Wan Azlina Ahmad, Wan Yunus Wan Ahmad, Zainul Akmar Zakaria, Nur Zulaikha Yusof

Environmental matters concerning non-stop use of artificial dyes observed a revival within the call for for typical dyes as common dyes show higher biodegradability and usually have the next compatibility with the surroundings. despite the fact that, one of many barriers at the use of normal dyes or pigments is the low extraction yield components (a few grams of pigment in keeping with kg of dried uncooked material). consequently, the exploitation of alternative organic resources similar to fungi, micro organism and mobilephone cultures deals attention-grabbing replacement. Microbial pigments resembling from bacterial origins provide the virtue by way of construction in comparison to pigments extracted from greens or animals, as a result of its easy telephone and quickly culturing method. This e-book deals fascinating perception into preliminary works conducted to illustrate the aptitude use of bacterial pigment as colorant for numerous applications.

The decrease in color intensity at high pH values can be attributed to the deprotonation of nitrogen by NaOH from the three conjugated rings at the pigment structure. This resulted in electron conjugations in the ring structure that gives it stability (Konzen et al. 2006). UV/vis analysis (200–800 nm scan; UV 1601PC; Shimadzu) of the crudeviolet pigment (Fig. 17 nm (pH 3, 7, 9 and 13). Methanol was used as blank. The primary reason for stronger absorption of the pigment at longer wavelength (visible region) was the electron conjugation effect.
