| Abstract: | The antagonistic protein produced by Bacillus subtilis A30 are resistant to many fungi. They are stable when treated with acid, alkali,heat and proteinase. The molecular weight of the antagonistic protein is higher than 30 kD. The minimal concentration of (NH 4) 2SO 4 to effectively precipitate the antagonistic protein is 20%. The active site is located in a domain smaller than 3 kD. |
