Limited degradation of industrial, synthetic and natural lignins by Serratia marcescens

Serratia marcescens was found to degrade kraft lignin by only 15%. When 14C-radiolabelled lignocelluloses and DHP lignins were used as substrates the bacterium mineralized to 14CO2 only 1.1-1.9% and 0.4-0.8% of the lignins respectively. However, some 44.4% of the 14C-beta-DHP lignin was recovered as...

Description
Summary:Serratia marcescens was found to degrade kraft lignin by only 15%. When 14C-radiolabelled lignocelluloses and DHP lignins were used as substrates the bacterium mineralized to 14CO2 only 1.1-1.9% and 0.4-0.8% of the lignins respectively. However, some 44.4% of the 14C-beta-DHP lignin was recovered as soluble radiolabelled products.
