In the original article, there was an error. Due to the oversight, a technical error was made in some parts of first two sentences, in the section Bacterial Isolates Used in Bioautography Assay. The corrections include the isolates code (IZB for the Xanthomonas strains), and the origin of the collection (Institute for Plant Protection and Environment, Belgrade, Serbia instead Laboratory of Microbiology, Faculty of Biology, University of Belgrade).
The corrected paragraph appears below:
The antibacterial activity of the Bacillus spp. extracts was measured against phytopathogenic bacteria Pseudomonas syringae pv. aptata (P16) isolated from sugar beets, and Xanthomonas arboricola pv. juglandis (IZB 301, IZB 311, and IZB 320; hereinafter referred to: 301, 311, and 320), originating from walnut trees. The phytopathogenic strains were previously identified and belong to the collection of the Institute for Plant Protection and Environment, Belgrade, Serbia.
The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way.
