| Abstract: | Antimicrobial substance from 96-79 showed strong antagonistic activity to many plant pathogens.Its physical and chemical properties were studied.The result indicated that this antimicrobial substance could keep active after 20 minutes'treatment at 120 ℃ or more than half year'treatment at 4 ℃.It was stable in the range of pH-value from 1 to 7.It could be dissolved in carbinol and water.Its molecular weight was mainly between 50000 and 100000 Da.This antimicrobial substance contained other antimicrobial components besides protein. |
| Keywords: | Antagonistic strain Antimicrobial substance Properties |
