Modeling the biodegradation of multicomponent organic matter in an aquatic environment: 3. Analysis of lignin degradation mechanisms
@article{Gubernatorova2010ModelingTB, title={Modeling the biodegradation of multicomponent organic matter in an aquatic environment: 3. Analysis of lignin degradation mechanisms}, author={T. N. Gubernatorova and Boris M. Dolgonosov}, journal={Water Resources}, year={2010}, volume={37}, pages={332-346} }
Mechanisms of enzymatic degradation of a persistent organic substance are discussed in the case of lignin. The major groups of lignin-decomposing microorganisms and their enzymatic systems are described. The biochemical mechanisms of the action of main lignin-decomposing enzymes are analyzed. Typical sizes of enzyme molecules are estimated. The results of analysis are used to formulate the major regularities of lignin destruction, which are required for the construction of a kinetic model of…

Leaf litter nutrient uptake in an intermittent blackwater river: influence of tree species and associated biotic and abiotic drivers
- Environmental Science

A substantial portion of detrital nutrients was not accounted for by living or dead plant and microbial biomass, especially in the case of N, which suggests increased importance of both N and P sorption to inorganic matter over time, with possible additional storage of N complexed with lignin.
