M.  a13C isotopic fractionation during biodegradation of agricultural wastes.h[electronic resource]  c2015  aIt has often been assumed that microbial metabolic processes are unimportant with respect to 13C isotopic fractionation in the biosphere when compared with photosynthesis. We have therefore examined the literature dealing with biodegradation by fungal and bacterial taxa of defined compounds, simple C3 and C4 sugars in artificial media and with more complex substrates of plant residues and animal excreta not in intimate contact with soil. These types of studies are fundamental to the interpretation of data from the more complex situations involving decomposition in soil or in the presence of plant roots, where the confounding effects of soil and root respiration exist.  aBiodegradação  aBiogeoquímica  aCarbono-13  aCompostos definidos  aFracionamento isotópico  aFungo de podridão branca  aResíduos agrícolas  aResíduos da colheita1 aINACIO, C.
