Application

Application	Comment	Organism
agriculture	the enzyme shows antifungal activity. It could become a natural alternative to synthetic fungicides to control certain important plant microbial diseases. The enzyme displays a wide inhibitory spectrum toward different fungi at a concentration of 20 AU. It has a strong inhibitor effect on mycelia growth and spore germination of Pythium ultimum	Aspergillus tubingensis
