ABSTRACT
The rise of multi-drug resistant microorganisms has become a major global challenge. This is mainly due to the over-use of antibiotics and the formation of biofilms. Quorum-sensing processes control biofilms, which are responsible for increased bacterial resistance. The present study was aimed to evaluate the antibiofilm and antiquorum sensing properties of Spirulina platensis. Antibacterial activity of several solvent extracts of against Pseudomonas aeruginosa and Staphylococcus aureus. The methanolic extracts were found to be more effective in considerably reducing biofilm formation, showing bacterial viability and affecting quorum sensing processes. The results suggest that microalgae are promising sources of alternative antibacterial chemicals.
