Isolation of Pseudomonas fluorescens from rhizospheric soil of faba bean and assessment of their Phosphate solubility: in vitro study, Ethiopia
Journal Title: Scholars Academic Journal of Biosciences - Year 2013, Vol 1, Issue 7
Abstract
Soil fertility improvement is an important area which needs attention since most of the hazardous inputs added into the agricultural system are in the form of chemicals. Since crop production and soil normal flora are affected by input of chemical fertilizer. Biofertilizer microorganisms make the nutrients available to plants. The present study was concerning to isolate of some Pseudomonas fluorescens species that possess a promising properties which make it a better bio-fertilizer bacteria. Twelve Pseudomonas fluorescens species was isolated from rhizospheric soil of faba bean and tested for phosphate solubilization. As result, all tested isolates Pseudomonas fluorescens species have a potential of phosphate solubilization on Pikovskaya media by formed a clear halo zone. So it could be summarized that all Pseudomonas fluorescens isolate species can be used as bio-fertilizers for soil fertiliy improvement, as a result increase crop growth and yield. Keywords: Bio-fertilizer, Clear halo zone, Crop, Phosphate solubilization, Pikovskaya media, Pseudomonas fluorescens
