Funded PhD Project (European/UK Students Only)
The Panama Disease of banana is caused by the fungus Fusarium oxysporum f. sp. cubense (Foc), threatening global production of banana. This studentship will be a partnership between the industry body Skyeast and Queen’s University Belfast to develop biological control methods to mitigate Panama Disease. The project will screen and enrich soil bacteria, which can limit the growth and pathogenesis of Foc and study the involved biochemical mechanisms. Through collaboration, the project will study interaction of the bacteria with soil components in the banana field.
The objectives of the project include:
Enrich chitinolytic microbiota in tropic soil: Into banana field and lab culturing system, chitin will be supplemented to encourage proliferation of chitinolytic microbials. Effectiveness of the enrichment will be assessed by monitoring chitinolytic activity along the process.
Monitor microbiota dynamics by rDNA phylogenetic analysis, isolate enriched bacteria and characterize their chitinolytic activity. rDNA interval will be amplified from the soil samples along the enrichment process and subjected to next generation sequencing to track the species got enriched by treatment of chitin. Following this, bacteria will be cultured on media. Bacterial clones will be screened for the target rDNAs. Matching bacteria will be amplified and subjected to chitinolytic activity measurement to find the strains with highest chitin degradation activities.
Characterize anti- Foc activity of the isolated microbials. Foc will be cultured before inoculating single and combined bacterial strains isolated in above objective. Growth of Foc will be quantified using standard protocols.
Interaction of the isolates with biochar products produced by the industrial partner. Each promising anti-Foc bacterium will be tested for their interaction with the East Sky biochar. Soil supplemented with different levels of the biochar will be inoculated by the isolates and the resulted mix will be then inoculated with Foc hyphea. After incubation, the abundance of the bacterium and the Foc will be quantified through culture-based measurements.
Test anti-Foc activity in the field. The effective combination of the bacterium and biochar identified in the lab will be applied to banana field in the presence of the Panama Disease to test effectiveness.
