Fractionation of nitrogen isotopes in the enzymatic deamination of alanine: an insight into the quantitative evaluation of anaerobic metabolism in ecosystems

Abstract Nitrogen isotope ratios of amino acids have been employed as a tool for illustrating the resource utilization of organisms and the trophic transfer between organisms in food webs. This tool is proposed based on the empirical observation that a universal trophic enrichment in 15N is found in...
