Abstract
Fosfor je esencijalan makroelement za rast biljaka, no često je nedostupan zbog svog oblika u tlu. Mikroorganizmi, posebno bakterije roda Pseudomonas spp., mogu otapati fosfor i činiti ga dostupnim biljkama. Provedeno istraživanje je bilo usredotočeno na usporedbu učinkovitosti autohtonih bakterija roda Pseudomonas spp. iz Osječko-baranjske županije u odnosu na čiste kulture bakterija. Korištene su tri čiste kulture bakterija (P. putida ATCC12633, P. rhizosphaerae DSM16299, P. fluorescens ATCC13525) te devet autohtonih sojeva izoliranih iz tla Osječko-baranjske i Vukovarsko-srijemske županije. Kulture su testirane na dvije vrste podloga s različitim koncentracijama fosfora: Pikovskaya’s agar (PIK) s 5 g L-1 i pripravak za testiranje otapanja fosfora (FOP) s 2 g L-1. Rezultati su pokazali da su bakterije roda Pseudomonas spp. uspješno otapale fosfor, što je potvrđeno pojavom prozirnih površina ispod bakterijskih kultura. Utvrđene su statistički značajne razlike između određenih sojeva bakterija.
Abstract (english)
Phosphorus is an essential macronutrient for plant growth but is often unavailable due to its form in the soil. Microorganisms, particularly Pseudomonas spp. bacteria, can solubilize phosphorus, making it accessible to plants. This study focused on comparing the effectiveness of indigenous Pseudomonas spp. bacteria from Osijek-Baranja County with pure bacterial cultures. Three pure bacterial cultures (P. putida ATCC12633, P. rhizosphaerae DSM16299, P. fluorescens ATCC13525) and nine indigenous strains isolated from soils in Osijek-Baranja and Vukovar-Srijem counties were used. The cultures were tested on two types of media with different phosphorus concentrations: Pikovskaya’s agar (PIK) with 5 g L-1 and a preparation for phosphorus solubilization testing (FOP) with 2 g L-1. The results indicated that Pseudomonas spp. bacteria effectively solubilized phosphorus, as evidenced by the formation of transparent zones beneath the bacterial cultures. Significant differences between some of the bacteria strains were observed.
