The effect of added l‐amino acids and NH 4 + on manganese peroxidase activity in ligninolytic cultures of Phanerochaete chrysosporium were investigated. Among 11 amino acids (0.2 mM) tested, including phenylalanine, glutamate, glutamine, histidine, alanine, iso‐leucine, ornithine, glycine, aspartate, proline, and arginine, phenylalanine was the most effective in suppression of manganese peroxidase synthesis. However, all the amino acids tested except proline completely suppressed the enzyme synthesis at 2 mM concentration.
