ABSTRACT:
Known microbiological methods are based upon the application of pigment-forming bacteria, in particularChromobacterium violaceum. The yield of these methods is very low, however, so that large industrial applications are not possible. However, in many fields of industry, there exists a very great demand for natural blue dyes which are substantially suitable for human digestion, which cannot be satisfied at present. Therefore, the method in accordance with the invention is characterized by the application of the newly discovered marine sediment bacteriumPseudoalteromonasspecies of the “Black Beauty” strain (originally deposited under file number DSM 13623 with the Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH., Braunschweig, Germany pursuant to the Budapest Treaty on the International Recognition of the Deposit of Microorganisms for the Purposes of Patent Procedure). Compared to conventional methods, this marine sediment bacterium leads to an about thirteen-fold yield. An application of the natural dyes produced economically and by simple technical processes is thus possible in consumer and environmentally friendly products, in particular those from the food, textile or toy industries.
