Summary
Partial oxygen limitation was shown to be the main reason for slow and incomplete degradation of lignin by Phanerochaete chrysosporium in non-agitated cultures. No oxygen could be measured in the mycelial mat deeper than 1 mm from the surface although the cultures were incubated under a 100% oxygen atmosphere. When the depth of the mycelial mat was reduced below the limiting thickness, the organism was able to degrade lignin in air at a rate comparable to that measured under 100% oxygen atmosphere.
