The PKB1-producing strain could
also be used as a biocontrol agent against blackleg
and other fungal diseases of canola. Application of
freeze-dried or living cells of the strain to canola
seeds protected the germinating seed from L. maculans
infection in the stubble. Another novel peptide
antibiotic agrastatin A (Fig. 3) was identified from the
culture broth of Bacillus subtilis strain AQ713
