Abstract

The heterotrophic microbiota (actinobacteria and other heterotrophic bacteria) of two Roman catacombs was characterised. Microbial isolates were identified using phenotypic methods, ribotyping and partial 16S rDNA sequencing. A total of 15 different actinobacterial and 29 other bacterial species were identified. The dominant micro-organisms were filamentous actinobacteria, mainly Streptomyces species (33%). The most commonly occuring other bacteria belonged to the genera Pseudomonas/Stenotrophomonas (28%), Bacillus (17%) and Staphylococcus (14%). In partial 16S rDNA sequencing the similarities to the until now described species indicated that many of these isolates (30%) are potential members of novel species, e.g. within the genera Amycolatopsis and Nocardia, or even within a new genus. Some species may have the ability to deteriorate mineral surfaces, but these properties of the isolates should be studied further.
