The study overviews results of bacterial incidence in in vitro plant tissue cultures obtained from commercial laboratory dealing with plants micropropagation. For the exploration, the 454 pyrosequencing of the 16S rRNA gene was used. Three samples of plant in vitro cultures with visual bacterial contamination were subjected for identification of present bacteria. Eleven genera as Acinetobacter, Lactobacillus, Methylobacterium, Roseomonas, Microbacterium, Mycobacterium, Curtobacterium, Acidovorax, Magnetospirillum, Chryseobacterium and Ralstonia were detected. Obtained results confirmed the advantages of high‐throughput amplicon sequencing analysis for identification of bacterial communities in contaminated plant in vitro cultures what provides an important information for applying appropriate measures to eliminate bacterial contamination.
