Isolation, Identification, and Biocontrol Potential of Plant Growth Promoting Rhizobacteria Pseudomonas fluorescens
Kalpesh Sorathiya, Shreya Kalariya, Lensi Patel
Abstract: The indiscriminate use of chemical pesticides and fertilizers caused incredible harm to the environment and ecosystem, including animals and humans. To replace such hazardous inputs added to the agricultural system, biological solutions are provided by nature in the form of microorganisms that have the capacity to promote plant growth without harming the environment. One solution for the control of different phytopathogenic agents is the use of biocontrol in the form of plant growth - promoting rhizobacteria (PGPR). The important group of bacteria Pseudomonas fluorescens belongs to the plant growth - promoting rhizobacteria that play a major role in the ability to adhere to soil particles and to the rhizoplane, motility, prototrophy, induced systemic resistance, and synthesis of antibiotics. Three Pseudomonas fluorescens species were isolated from Rhizospheric soil and produced fluorescent pigments on King?s B medium and Nutrient Agar medium. By using the dual culture technique, the efficacy of bacterial antagonists in controlling the fungal pathogen Fusarium solani was determined. The present study refers to the isolation, identification, and antagonistic activities of selected isolates. The isolate 1 strains could serve as promising bioagents, although further in situ investigations are needed.
