Environmental concerns regarding continuous use of synthetic dyes saw a revival in the demand
for natural dyes as natural dyes exhibit better biodegradability and generally have a higher
compatibility with the environment. However one of the limitations on the use of natural dyes
or pigments is the low extraction yield factors (a few grams of pigment per kg of dried raw
material). Therefore the exploitation of other biological sources such as fungi bacteria and
cell cultures offers interesting alternative. Microbial pigments such as from bacterial origins
offer the advantage in terms of production compared to pigments extracted from vegetables or
animals due to its simple cell and fast culturing technique. This book offers interesting
insight into initial works carried out to demonstrate the potential use of bacterial pigment as
colorant for various applications.
