INTRODUCTION

BIOCOLOUR, word consists of two words BIO meaning natural and COLOURmeaning anything which is used for colouring purpose.

Biocolour is any dye obtained from any vegetable, fruits, plant, microorganisms,

animal or mineral, that is capable of colouring food, drugs, cosmetics or any part

of human body.

The production of the synthetic colourants is economically efficient and

technically advanced but many artificial synthetic colorants, usuallyused in foodstuff, dyestuff, cosmetics and pharmaceutical

manufacturing processes, causes various hazardous effects like toxic

diseases such as cancer and other behavioral problems in children.

To counteract the ill effects of synthetic colourants, there is worldwide

interest in process development for the production of pigments andcolours from natural sources.

PRODUCTION

(igment e1traction from the bacterial cells can be carried out by first

centrifuging the cells and discarding the supernatant. #he cell pellets are then

rinsed with deioni3ed water, followed by centrifugation to recover the cells by

discharging the supernatant again. #he recovered cells are then fully mi1ed with

ethanol -with a purity of AA.@G. #he mi1ture of the cells and ethanol is treated

by ultrasonication until the cells are completely bleached. #he ethanol e1tract isthen separated from the cells by centrifugation.
