Cilj ovog rada je bila analiza rizosfere sočivice kao mesta aktivne produkcije auksina bakterijskog porekla, primarno indol-3-acetatne kiseline (IAA). Produkcija IAA je testirana na 21 različitom bakterijskom soju. Četiri bakterijska soja: Pseudomonas oryzihabitans 15, Pseudomonas putida 23, Hafnia paralvei 43 i Pseudomonas yamanorum 47 odabrana su na osnovu povećane produkcije IAA u odnosu na ostale testirane sojeve. Ovi sojevi su pokazali neprekinutu produkciju IAA i pod nepovoljnim uslovima: u kiseloj i baznoj sredini, kao i u hipersalinoj sredini. Naši rezultati sugerišu da ovi sojevi mogu imati biotehnološku primenu u zaštiti biljaka i povećanju prinosa putem produkcije auksina kao centralnih regulatora rasta i razvića biljaka.
