Cichorium intybus L. Hairy Roots as a Platform for Antimicrobial Activity

Area of Science:

• Plant Biotechnology
• Pharmacognosy
• Microbiology

Background:

• Industrial chicory (Cichorium intybus) is cultivated for dietary fiber and bioactive secondary metabolites.
• Hairy roots are plant cell cultures recognized for producing valuable plant-derived molecules.
• Assessing novel sources of antimicrobial agents is crucial for public health.

Purpose of the Study:

• To establish industrial chicory hairy root cultures.
• To evaluate the antimicrobial potential of these hairy root extracts.
• To compare the antimicrobial activity with conventional chicory taproots.

Main Methods:

• Establishment of industrial chicory hairy root cultures.
• Preparation of hot water extracts from hairy roots and taproots.
• Antimicrobial activity assays against relevant human microbial pathogens.

Main Results:

• Chicory hairy root extracts demonstrated significant antimicrobial activity against tested human microbes.
• Conventional chicory taproot extracts showed no significant antimicrobial activity.
• Notably, chicory hairy root extracts exhibited potent activity against methicillin-resistant Staphylococcus aureus (MRSA).

Conclusions:

• Industrial chicory hairy roots are a promising biotechnological system for producing antimicrobial compounds.
• Hairy root cultures offer a viable alternative to conventional plant sources for antimicrobial agent production.
• The identified antimicrobial properties highlight the potential of chicory hairy roots for pharmaceutical applications.
