P5 PEPTIDE HAVING ANTIALGAE ACTIVITY AGAINST ORGANISM INDUCED RED TIDE AND THE USE OF THE SAME

摘要

PURPOSE: An anti-red tide peptide P5 with anti-red tidal activity is provided to ensure excellent red tidal activity without toxicity. CONSTITUTION: A P5 peptide has an amino acid sequence of sequence number 2. The P5 peptide is a peptide or derivative with enhanced positive charge and hydrophobic region by substituting one or more amino acids of CA-MA(crecropinA-magainin 2) peptide of sequence number 1. The P5 peptide has an anti-red tidal activity to C. polykrikoides, C. marina, or H. akashiwo. An anti-red tidal composition contains P5 peptides as an active ingredient.
