The Green Frontier: Antimicrobial Power of Microalgae and Cyanobacteria In the global race against antibiotic resistance, nature has provided a microscopic solution that has existed for billions of years.  Microalgae and cyanobacteria  are no longer just "pond scum"—they are sophisticated chemical factories capable of producing potent  antimicrobial compounds . Why Microalgae? Unlike traditional land plants, these microorganisms live in high-stress environments. To survive, they synthesize secondary metabolites that act as a defense system against pathogens. These compounds—ranging from fatty acids and proteins to complex polyphenols—exhibit remarkable efficiency in inhibiting the growth of bacteria, fungi, and even some viruses. Key Bioactive Compounds Fatty Acids (PUFAs):  Known to disrupt bacterial cell membranes. Peptides:  Many cyanobacteria species produce "cyanotoxins" which, in controlled doses, act as powerful antifungal agents. Pigments:  Phycobil...
