1. A method for the biotechnological production of the blue-green fungus pigment xylindein in a bioreactor, comprising the steps of
(a) bringing the reactor contents into contact with a biomass of the fungus
culture Chlorociboria sp. and stirring the reactor contents to form xylindein-containing biomass,
(b) separating the xylindein-containing biomass which formed in step (a), and
(c) extracting the xylindein from the biomass separated in step (b) using a solvent, wherein the biomass with which contact is made in step (a) is an uncoloured biomass.
