This work aims at developing a more accurate measurement of the physical parameters of fractal dimension and the size distribution of large fractal aggregates by small-angle light scattering. The theory of multiple scattering has been of particular i

Laccase activity of forest litter

Autor: S Tagger, G Vogt, J. Le Petit, Stéven Criquet, Gilles Iacazio

Publikováno v: Soil Biology and Biochemistry. 31:1239-1244

Laccases are blue-copper enzymatic proteins involved in the transformation of polyphenolic compounds, such as lignin, into forest litter. A method to measure their activity was developed using an evergreen oak litter as a model system. We considered
