Abstract

The global rise in antimicrobial resistance has heightened the quest for new and efficient antimicrobial agents. Marine seaweed is a rich source of several amino acids, fatty acids, and dietary fibers, as well as polysaccharides, polyphenols, pigments, and other active substances, which play crucial roles in various biological processes such as antioxidant activity, immunoregulation, and anti-inflammatory response. These diverse bioactive compounds found in seaweeds offer a promising natural source of antimicrobial substances. This review explores the antimicrobial properties of various seaweed compounds, including polysaccharides, phenolic compounds, lipids, pigments and focuses on how these chemical compounds inhibit microbial growth. The review study highlights the role of seaweed chemical compounds inhibit microbial growth and discusses their potential applications in derived compounds in combating the growing problem of drug-resistant infections as well as their potential as alternative therapeutic agents.

Key words: Marine seaweed, bioactive compounds, antimicrobial resistance, polysaccharides.
