Özet:

 Plant growth-promoting rhizobacteria PGPR, which colonize the rhizosphere, are eco-friendly and beneficial bacteria that directly or indirectly promote plant growth. In this study, 13 isolates from the rhizosphere of Rosmarinus officinalis L. Rosemary were identified using MALDI-TOF-MS to assess morphology, biochemistry, and plant growth-promoting traits and to evaluate their antagonistic effects against Fusarium oxysporum. Among all isolates, 9 isolates fixed nitrogen, 8 isolates dissolved inorganic phosphate, 8 isolates produced siderophores, 7 isolates produced IAA Indole-3-Acetic Acid, and 6 isolates produced HCN. Isolate BBR-6 showed the highest antifungal activity against Fusarium oxysporum, with an inhibition rate of 61.54 . The isolate BBR-10 19.40  showed the weakest effect against F. oxysporum. Although research on PGPRs has increased recently, research on rosemary is still limited. This study aimed to identify the local bacterial community in the rhizosphere of rosemary and assess its growth-promoting properties and antifungal activity against disease-causing F. oxysporum, potentially acting as a microbial fertilizer and biocontrol agentents.

 Bitki büyümesini teşvik eden rizobakteriler PGPR, rizosferde kolonize olan, doğrudan ya da dolaylı olarak bitki büyümesini destekleyen çevre dostu faydalı bakterilerdir. Bu çalışmada, Rosmarinus officinalis L. Biberiye rizosferinden on üç izolat MALDI-TOF-MS methodu ile tanımlanarak morfolojik, biyokimyasal, bitki büyümesini teşvik edici özellikleri ile Fusarium oxysporuma karşı antagonistik özellikleri değerlendirildi. Tüm izolatlar arasında 9 izolatın azot fikse ettiği, 8 izolatın norganik fosfatı çözdüğü, 8 izolatın siderofor ürettiği, 7 izolatın IAA indole-3-acetic acid ürettiği ve 6 izolatın HCN ürettiği belirlendi. BBR-6 izolatı, Fusarium oxysporuma karşı  61.54lük bir inhibisyon oranıyla en yüksek antifungal aktiviteyi gösterdi. BBR-10 izolatı ise  19.40 ile F. oxysporuma karşı en zayıf etkiyi gösterdi. PGPRler üzerindeki araştırmalar son zamanlarda artsa da biberiye üzerine yapılan araştırmalar hala sınırlıdır. Bu çalışma, biberiye rizosferindeki yerel bakteri topluluğunu tanımlamayı, bitki büyümesini teşvik edici özelliklerini, mikrobiyal gübre ve biyokontrol ajan potansiyeli ile biberiye bitkisinde kök hastalığa neden olan F. oxysporuma karşı antifungal aktivitesini değerlendirmeyi amaçlamaktadır.
