ANTI-RED TIDE PEPETIDE WITH ANTIALGAE ACTIVITY AGAINST ORGANISM INDUCED RED TIDE, THE USES THEREOF AND THE PREPARING METHOD

摘要

PURPOSE: A peptide for preventing red tide is provided to ensure excellent anti-tidal activity without cytotoxicity and enable natural decomposition. CONSTITUTION: A peptide for preventing red tide has an amino acid which is substituted from positive charge to negative charge in a helix peptide with antibiotic activity. The amino acid with positive charge is a hydrophilic part. A peptide of helix structure with antibiotic activity is an amino acid of sequence number 1. A peptide for preventing red tide is an amino acid of sequence number 2. A composition for preventing red tide contains a peptide of sequence number 2 as an active ingredient. The composition has prevention activity to Alexandrium sp., Alexandrium catanella, Skeletonema costatum, or Prorocentrum minimum.
