Multiple sequence alignment of a part of the 16S rRNA gene of Mycobacterium species isolated from water samples. Sample sequences obtained through PCR sequencing of the 16S rRNA gene were aligned with those of type strains of species resembling the isolated mycobacteria. Species-specific variable region is indicated. * – mixed sample in August identified by two different overlapping chromatograms at the positions indicated by N and highlighted in pink. Chromatogram 1 – ATGGGATGCATGTTC = M. terrae Chromatogram 2 – GCGCGCTTCATGGTG = M. engbaekii
