Abstract
We report here on bioturbation traces, with micro-dendrite
textures, composed of a mixture of altered aluminum and polycarbonate,
which have been developed in a common compact disk (CD), destroying
information pits. Fungal hyphae proliferated in these deteriorated
zones, and Geotrichum-type fungus was isolated from surface-sterilized
CD fragments. The severe biodeterioration described is attributed to the
slow growth of this arthroconidial fungus on the CD material in the
tropical indoor environment of Belize, Central America (~30°C, ~90%
humidity).
