Distributions of amino acids in some Florida peats have been compared with distributions in plants living now at the surface of the peats and in surface litter. Quantitative determinations were made by gas chromatography of volatile derivatives of both protein and non-protein amino acids. The latter. found also in mineral soils, are believed to represent bacterial cell constituents and/or anabolites. , -diaminopimelic acid, a constituent of the mureide complex of bacterial cell walls, was found in peats and surface litter, as were other acids believed in soil ecosystems to result from the living processes of microorganisms. The protein amino acids in peats do not show a distinctive signature of any particular kind of organism, but the nature and concentrations of the non-protein acids support the inference that the higher plant constituents are extensively re-worked and that essentially all of the amino acid material in peats is microbial in proximate origin. Thus microbial amino acids appear to be quite significant participants in the input to coalification.
