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.
