PhD progress presentation

rhizobacterial biofilms

  • Synergistic relation with plants and colonies roots
  • Resistant to organic and inorganic pollutants
  • Antimicrobial agents
  • Produce antibiotics and kill pathogens
  • Use signal system under polluted environment and assist plants to cope with stress conditions
  • Help plants in improving growth and biomass

Evaluation of quorum sensing system in rhizobacterial biofilms for inducing resistance in plants against heavy metal resistance.

Introduction to biofilms

Statement of purpose

  • Biofilms are densely packed communities of microbial cells that grow on living or inert surfaces and surround themselves with secreted polymers.
  • Biofilms secrete extra-cellular polymeric substances (EPS) give the biofilm its chemical properties
  • Achieve cell to cell communication via signal molecules in a system called Quorum sensing (Ren et al., 2015)
  • Weak associations of bacteria with host plant root makes plant growth promotion difficult besides the fact that bacteria are resistant to pollutants and pose multiple plant growth regulating traits.

  • The impact of biofilms in plant growth improvement and phytoremediation has not been received adequate attention and studies of beneficial biofilms communities are thus needed to be studied.
