Interakce mikroorganismů a rostlin v zemině kontaminované PCB a jejich význam při fyto/rhizoremediaci Interactions of microbes and plants and their importance in fyto/rhizoremediation in PCB contaminated soil
Bioremediation, the usage of biological systems for removing pollutants from the environment, is an effective tool of microbial
ecology. Plants and microorganisms are part of the nature and the use of these systems for remediation does not lead to a negative
intervention to the environment. Methods for characterization and identification of cultured microorganisms (mass spectrometry
MALDI-TOF) and non-cultured microorganisms (SIP, T-RFLP, etc.) able to degrade PCBs has been developed recently. Microorganisms
isolated from the contaminated soil can be used for other bioremediation purposes. Plants play an important role in the removal
of xenobiotics from the environment as well. They are able to absorbe pollutants from the contaminated soil, transform them
to non-phytotoxic forms and store them in their tissues. Plants also positively affect the rhizosphere microbes by releasing
compounds supporting bacterial growth and activity. Plants release secondary metabolites that are potential inducers of the expression
of genes involved in the bacterial degradation pathway of PCBs. Higher concetration of these compounds in the rhizosphere could
lead to better degradation of these compounds.
