o:3718 Isolation of rhizobacteria of sessile oak (Quercus petraea (Matt.) Liebl.) from the forests of eastern Serbia and their preliminary identification Изолација ризобактерија храста китњака (Quercus petraea (Matt.) Liebl.) из шума источне Србије и њихова прелиминарна идентификација en Rhizobacteria are a heterogeneous group of bacteria inhabiting the rhizosphere of plants, whose dynamics and diversity of metabolism and activity are conditioned primarily by root exudates. Functionally, these bacteria contribute to the improvement of plant performances, and are often members of the genera Bacillus and Pseudomonas. The rhizobacteria of forest species in Serbia have not been sufficiently studied. Sessile oak is one of the most important oak species in Serbia and one of the most produced species in forest nurseries. In this study, the rhizobacteria of sessile oak from natural populations of eastern Serbia are isolated and the representatives of genus Bacillus, i.e., Pseudomonas are identified preliminarily. Out of a total of 94 isolates, 35 were preliminarily identified as Bacillus spp., and out of 29 Gram-negatives, some of the isolates belong to genus Pseudomonas. Further research is necessary in order to identify the isolates more precisely and examine their impact on sessile oak. rhizobacteria, sessile oak, identification, Bacillus, Pseudomonas, eastern Serbia 1552101 1821-1046 1552099 10.5937/SustFor2183001J 2024-01-12T11:04:32.405Z 44 no 46 Сања Јовановић 0000-0001-9468-2628 46 Берић Тања 46 Александар Лучић 0000-0002-4473-1791 46 Станојевић Оља 0000-0002-0350-9318 46 Владан Поповић 0000-0003-4326-3364 application/pdf 274705 https://unilib.phaidrabg.rs/o:3718 no yes 1 70 1552253 Sustainable forestry 83-84 1 12 Институт за шумарство, Београд, Србија 2021
