The effect of amino acids was examined in cufing “akagusare”, or red rot disease, of the layer Porphyra spp. Among the amino acids tested, histidine, methionine, and tyrosine were found effective: the infected layer recovered when treated for 23days with mineral-enriched seawater containing each amino acid at a level of 10ppm. Histidine showed the highest activity against the causative fungi. The time of recovery for an infected layer was shortened to 12h when the level of histidine was increased to 100ppm. Moreover, the treated layer was prevented from reinfection with the fungi, and freed from the disease for at least 2 weeks. In a similar experiment in natural environment, histidine was also found to cure, or protest against disease, the young bud, young frond, and thallus of the layer.
