Title (EN) ISOLATED MELANIN-LIKE SUBSTANCE AND METHOD FOR PRODUCING THE SAME
(FR) ISOLEMENT D'UNE SUBSTANCE ANALOGUE DE LA MELANINE ET SON PROCEDE D'OBTENTION
Abstract:
(EN) The production of a melanin-like compound by introducing an inactivated virus into a culture of bacteria is disclosed. After introduction, the inactivated virus causes a phenotypic change in the bacteria. When introduced into a media containing tyrosine, these modified bacteria produce a melanin-like compound, pyomelanin. The bacteria will continue to produce pyomelanin until they are removed from the tyrosine source.
(FR) L'invention porte sur l'obtention d'un composé analogue de la mélanine par introduction d'un virus inactivé dans une culture de bactéries. Après l'introduction, le virus inactivé entraîne une modification phénotypique de la bactérie. Si l'introduction se fait dans un milieu contenant de la tyrosine, les bactéries modifiées produisent un composé analogue de la mélanine. Les bactéries continueront à produire de la pyomélanine jusqu'à ce qu'on les retire de la source de tyrosine.
