The present invention relates to a process for the production of a dyed biopolymer comprising the steps of providing at least one biopolymer-producing microorganism, providing at least one dye-producing microorganism, culturing said at least one biopolymer-producing microorganism to produce at least a biopolymer,and culturing said dye-producing microorganism wherein said dye-producing microorganism produce at least a dye suitable to dye at least part of said biopolymer, whereby a dyed biopolymer is obtained.The present invention also relates to a dyed biopolymer, to process for the production of a dyed composite article comprising at least the dyed biopolymer and to articles comprising the dyed biopolymer. La présente invention concerne un processus de production d'un biopolymère coloré comprenant les étapes consistant à fournir au moins un micro-organisme producteur de biopolymère, à fournir au moins un micro-organisme producteur de colorant, à cultiver ledit ou lesdits micro-organismes producteurs de biopolymère afin de produire au moins un biopolymère, et à cultiver ledit micro-organisme producteur de colorant, ledit micro-organisme producteur de colorant produisant au moins un colorant approprié pour colorer au moins une partie dudit biopolymère, moyennant quoi un biopolymère coloré est obtenu. La présente invention concerne également un biopolymère coloré, un processus de production d'un article composite coloré comprenant au moins le biopolymère coloré et des articles comprenant le biopolymère coloré.
