Detection of nitrogen stable forms in marine sediments by high resolution magic angle spinning (HRMAS) 1H nuclear magnetic resonance (NMR)

José M. de la Rosa et al.-- 2 pages, 13 references.-- Póster SSS24-1MO5P-0442, presentado en la sesión Poster Programme - SSS24 Soil organic matter – cycling of elements and characterization of stable C pool(s) (co-listed in BG).-- Congreso celebrado del 2 - 7 de abril, 2006, en Viena, Austria.Nitrogen 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).Nitrogen occurring in sedimentary organic matter (SOM) mainly derives from living organisms.
