AbstractNitrogen occurring in sedimentary organic matter (SOM) mainly derives from living organisms. Proteins and peptides, the most abundant nitrogen containing substances in SOM, have been traditionally considered as part of the labile fraction in the environment. On the other hand, recent studies have shown that proteinaceous material can resist microbial degradation in sedimentary environments and consequently a portion of the nitrogen is incorporated into biologically refractory organic material and removed from the active nitrogen pool (Knicker et al, 1996, Pantoja and Lee, 1999; Nguyen and Harvey, 2001; Knicker and Hatcher, 1997, 2001; Zang et al, 2001).
