| Abstract | The aim of this study was to evaluate actinomycetesfor plant growth-promoting(PGP)traitsusing in vitro experiments. Actinomyceteswere isolated from twodifferent soil rhizospheresandsubjected to dual culture experimentsin order todetermine antimicrobial activity. Subsequently, selected isolates with potent antimicrobial activity were examined further fortheirability to biosynthesize indole-3-acetic acid (IAA) andsiderophores, solubilize inorganicphosphate,and produce ammonia.Results showed that these strains produced38.73-211.35 ng/mLIAA in Tryptic Soy Broth (TSB),andsolubilized 116.20-319.33 ?g/mLinorganic phosphatein National Botanical Research Institute's phosphate growth medium (NBRIP)broth.Additionally, all selected actinomycetes producedsiderophores in chrome azurol S (CAS) agar and ammonia in peptone water. Five isolates showed promise as plant growth promoters, with isolates SNN045, SNN056, and SNN059 being the most plausible candidates for agricultural applications. |
