Abstract:
The active stalactites from Grotta dei Cervi, Porto Badisco, southeastern Italy, were sampled to investigate the microbial communities present in these speleothems. Sampling was carried out in a transect about 150 m long in the central gallery, where numerous Gram-positive bacteria were isolated. Actinomycetes of the genus Streptomyces were the most abundant, followed by members of the genus Bacillus. Further isolates were assigned to the genera Amycolatopsis, Arthrobacter; Agromyces. Micrococcus, Nocardiopsis and Rhodococcus of the order Actinomycetales. The ability of actinomycetes to colonize subterranean environments is discussed.
