The Spanish scientific magazine Ciencia Digit@l writes that a fungus has been discovered that can ‘eat’ CD-ROMs. The geotrichum organism takes in the carbon and nitrogen of the polycarbonate layer on a CD, after which the information is completely destroyed. Until now, the polycarbonate was thought to be practically indestructible.
Fortunately, the fungus only lives under tropical conditions: a temperature of 30 degrees Celsius and a humidity of 90 percent. So you don’t have to be afraid that in a while a fully eaten family of geotrichum will be found in your CD rack. Who knows, the voracious fungus can be used in a positive way, for example to break down unusable CDs in an environmentally friendly way.
A quote translated by Altavista:
A group of geologists and biologists of the National Museum of Natural Sciences and of the Biological Research center of the CSIC has discovered a fungus of Geotrichum type, that feeds on carbon and the nitrogen of polycarbonate the plastic layer of the Compact Disc and destroys the recorded tracks of information in the aluminum layer.
The CD of musical contents in which the bioturbación took place that gave foot to the investigation was found in Belize (Central America), the structure of a CD is made up essentially of a polycarbonate base, that is plastic the transparent one that covers the surface
