| Abstract: | Using agar diffusion method in this experiment, It was found that both the clone and culture supernent from antagonistic strain TCCC11322 showed visible inhibition effect in the growth of Saprolegnia parasitiea strain XJ001.Using culture supernet,crud protein,crud polysaceharides and small peptide compounds was extracted respectively and further investigation was conducted.The experimental results demonstrate that the secret suprenent protein is the active antagonistic constituent to Saprolegnia parasitiea. |
