MICROBIOLOGICAL METHOD FOR THE BIOSYNTHESIS OF NATURAL BLUE-VIOLET COLORANTS VIOLACEIN AND DESOXYVIOLACEIN AND THE UTILIZATION THEREOF

摘要

Known microbiological methods are based on the use of pigment-forming bacteria, especially Chromobacterium violaceum. Said methods are low-yielding and, therefore, large scale applications are not possible. However, the demand for natural blue colorants, which are generally human compatible, is high in many industrial branches and is currently not covered. For this reason, the method according to the invention is characterized in that it uses the marine sediment bacterium Pseudoalteromonas spezies, strain "Black Beauty" as a pigment-forming bacterium. With said marine sediment bacterium, the yield increases approximately thirteen times in comparison with known methods.
