Anotace	The genetic diversity of streptomycetes in colliery spoil heaps (Sokolov), Czech Republic) was investigated by restriction pattern analysis of 165-internal transcribed spacer rDNA and 165 sequences. We sampled freshly excavated Miocene sediment (17-19-million-year-old) and four sites of primary succession (initial, early, middle, and late stages; aged 1-44 years) on the same sediment. Active bacteria were present even in fresh Miocene sediment, and the relative proportion of actinomycetes among total bacterial and their genetic diversity increased significantly with the age of the sampling site. The replacement of pioneer species by late succession species during succession was observed. Plate assays of Streptomyces strains revealed 27% antibiotic-producing strains. Screening for nonribosomal peptide synthases and type I polyketide synthases systems suggested that 90% and 55% streptomycetes, respectively, are putative producers of biologically active compounds.
