AB  - Biljke, uključujući i konoplju (Cannabis sativa L), su domaćini različitih korisnih mikrobnih zajednica. Ovi mikroorganizmi se mogu naći u rizosfernom zemljištu, na biljci ili unutar biljnih tkiva, i svi zajedno čine biljnu mikrobnu zajednicu. Mikroorganizmi označeni kao biljna mikrobna zajednica se sistematski proučavaju dugi niz godina, i velika većina naučne literature se slaže oko njihove centralne uloge u podržavanju rasta, razvoja i opšteg zdravlja biljke. Cilj ovog istraživanja bio je da se iz rizosfernog zemljišta konoplje (Cannabis sativa L) izoluju bakterije roda Pseudomonas, Bacillus i Azotobacter i ispita njihov biostimulatorni (PGP od plant growth-promoting) i biokontrolni potencijal. Ova studija je potvrdila da autohtone rizosferne bakterije konoplje imaju različite sposobnosti tolerancije na abiotičke faktore i više različitih svojstava kojima mogu podstaći rast biljaka. Izolati roda Pseudomonas su pokazali sposobnost da žive na niskim (10ºC) i visokim (37 ºC) temperaturama. Svi izolati su imali minimalan rast na pH 9. Dva izolata označena kao P37 i P39 su tolerisala visoke koncentracije NaCl. Izolati su imali sposobnost da koriste različite izvore ugljenika. Svi Pseudomonas izolati produkovali su lipazu, ureazu, siderofor, cijanovodonik i razlagali jedinjenja organskog i neorganskog fosfora.
AB  - Plants, including hemp (Cannabis sativa L), host different beneficial microbial communities. These microorganisms can be found in rhizospheric soil, on and inside plants tissues, designated as the plant microbiota or plant-associated microorganisms. The plant-associated microorganisms have been studied systematically for many years, and the vast majority of the scientific literature agrees upon their central role in supporting plant growth, development and overall health. The aim of this study was to isolate bacteria of Pseudomonas, Bacillus, and Azotobacter from the rhizospheric soil of hemp (Cannabis sativa L.) and investigate their biostimulatory (plant growth-promoting – PGP) and biocontrol potential. This study confirmed that indigenous rhizospheric bacteria of hemp have different abiotic stress tolerance abilities and multiple plant growth-promoting (PGP) properties. Pseudomonas isolates showed the ability to live at low (10ºC) and high (37 ºC) temperatures. All isolates had minimal growth on pH 9. Two isolates denoted as P37 and P39 tolerated high concentrations of NaCl. Isolates had the ability to use different sources of carbon. All Pseudomonas isolates produced lipase, urease, siderophore, hydrogen cyanide, and utilized organic and inorganic phosphorus.

AB  - The objective of this study was the isolation and characterization of Azotobacter, Pseudomonas
and Bacillus species from the rhizospheric soil of Mellisa officinalis and to examine the effect of
isolates application on the seed germination and seedling growth. Isolation, physiological,
biochemical, and plant-growth-promoting activity characterization of isolates were done.
Monitoring the effects of isolates application on seed germination and seedling growth were
evaluated in controlled conditions. The number of germinated seeds, the shoot and root length of
seedlings, vigour index and biochemical stress markers (lipid peroxidation intensity and total
phenols) were measured. From the rhizosphere of plant 2 Azotobacter (denoted as A5 and A6), 5
Pseudomonas (denoted as P27, P28, P29, P55 and P56) and 6 Bacillus (denoted as B64, B65,
B66, B67, B68 and B69) bacteria were isolated. Azotobacter isolates showed the ability to live in
the condition of low (5) and high (9) pH. The isolates varied in terms of the utilization of carbon
sources. Both isolates produced pectinase, hydrogen cyanide (HCN) and utilized organic and
inorganic phosphorus. Pseudomonas isolates had optimal growth at 10 ºC and 37 ºC, and on
medium with pH 5 and 9. All Pseudomonas isolates could produce pectinase, lipase, amylose,
IAA, siderophores and HCN. All Bacillus isolates could grow on a medium containing 7% NaCl.

AB  - The aim of the study was to investigate ability of Pseudomonas sp. Q4b, Bacillus sp. Q5a and Azotobacter chroococcum strain 8 to enrich a population of plant growth promoting rhizobacteria (PGPR) in rhizosphere and thus enhance maize growth (Zea mays L.). Experiments were carried out under greenhouse and field conditions, on a chernozem soil. In vitro screening for PGP properties showed significant difference between indole-3-acetic acid (IAA) and siderophores production and phosphosolubilization between Pseudomonas sp. Q4b and Bacillus sp. Q5a. Pseudomonas was estimated as a better producer of hydrogen cyanide (HCN) and siderophores than Bacillus. Bacterial treatments had a significant effect on the number of investigated microbial groups in rhizosphere, and maize growth and yield. Co-inoculation had an advantage compared to single inoculation, while in case of single strains, better effects were achieved in Pseudomonas and Azotobacter treatments. Inoculation increased the number of azotobacters (103.25%), pseudomonads (82.29%) and aerobic spore-forming bacteria (52.65%) as well as height (17.15%) and dry weight (35.48%) of maize plants. The highest plant height was recorded in treatment with Pseudomonas and Bacillus. The highest dry weight and yield were recorded in the treatment with mixture of these three strains.
