Amino acid control mechanism for bacitracin formation by Bacillus licheniformis.

Several amino acids affected the amount of bacitracin produced by Bacillus licheniformis ATCC 10716 and the high-yielding mutant B. licheniformis AL. The possibility of an amino acid control mechanism for bacitracin biosynthesis is discussed. The two strains showed a different response to the addition of some amino acids. This indicate that they may have differences in their amino acid control mechanism.
