title: Molecular analysis of 16S-23S spacer regions of Acetobacter species.
abstract: 16S-23S rDNA internal transcribed spacer regions (ITS) similarities were determined in 8 Acetobacter and 1 Gluconacetobacter strains. ITS-PCR amplification of the 16S-23S spacers showed 2 products of similar size in 7 strains; only 1 product of similar size was found in the 2 remaining strains. Analysis of the PCR products using restriction endonucleases HaeIII, HpaII and AluI revealed 3 different restriction groups of A. pasteurianus for AluI and HaeIII, and 4 restriction groups for HpaII. ITS nucleotide sequences of all studied strains exhibited a 52-98% similarity.
