Abstract
  • The aim of this thesis was to investigate the effect of phytohormone supplementation on Pseudomonas spp. cultures and identify the hypothetical promotion of biocontrolling properties and reduction of phytopathogenic properties of select species of Pseudomonas. Representative species of Pseudomonas included: P. aeruginosa, P. putida and P. syringae, which were analysed for changes in lifestyle and development, including: colony motility, biofilm formation, dispersal, and several secreted factor analyses. The results show the wide effect of phytohormone supplementation and the division of effect by the phytohormone assayed (between salicylic acid and auxin) and the individual species’ response. Trending stimulation of motility at low concentrations and reduction of biofilm formation and subsequent dispersal was present in majority of strains, however. Insight from investigation allows for further postulation on the usage of phytohormone supplementation to modulate Pseudomonad populations.
