Abstract
This study sought to produce ecofriendly ink from a microbial source to minimize the use of synthetic inks which are non-degradable. Serratia marscescens was isolated from a soil sample and used to produce red coloured pigment called Prodigiosin. Optimization parameter was done to maximize the pigment production. Purification of the pigment was performed by means of Column Chromatography and Thin Layer Chromatography. Ecofriendly and biodegradable ink was produced using prodigiosin may serve as an excellent alternative to synthetic inks and itâs also known for its stability, colour, brightness and longevity.
