Isolation of rhizobacteria of sessile oak (Quercus petraea (Matt.) Liebl.) from the forests of eastern Serbia and their preliminary identification
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.
