“…Thimerasol does not affect the oxidation process of phenolic compounds (Wang et al 1983). In order to investigate the effect of the molar ratio of catechol to Maillard reagents, a number of treatments were employed with increasing amounts (0, 0.0025, 0.0250, 0.0500, 0.1000 moles) of catechol added to a fixed molar ratio of Maillard reagents (0.05 mole glucose'0.05 mole glycine) using birnessite as catalyst following suggestions by Jokic et al(2004). There was also a treatment containing 0.05 mole catechol and birnessite.…”

“…The flasks were then tightly sealed and placed in a constant temperature water bath at 458C for a period of 15 d while gently shaking. Forty-five degrees centigrade is an environmentally relevant temperature as it is common in tropical and subtropical areas, and is the approximate temperature of an exposed sunlit soil surface on a day when the ambient air temperature is 258C (Jury et al 1991). All treatments were performed in triplicate.…”

“…Aerobic microbial growth was tested for by culturing on Tryptocase Soy Agar plates, while anaerobic microbial growth was tested for on Tryptocase Soy Agar plates in a BBL GasPak 150 Large Anaerobic System. All cultures were incubated for a period of 9 d at 288C (Jokic et al 2004).…”

“…The significance of linking the polyphenol pathway and Maillard reaction into an integrated polyphenol-Maillard humification pathway, which is pertinent to nature, where sugars, amino acids and polyphenols coexist in solution, was first shown by Jokic et al (2004) using birnessite (d-MnO 2 ) as a catalyst. Mn(IV) oxides, such as birnessite, are known to be powerful catalysts of abiotic humification reactions (Huang 2000).…”

“…Mn(IV) oxides, such as birnessite, are known to be powerful catalysts of abiotic humification reactions (Huang 2000). It has previously been shown that during abiotic humification reactions catalyzed by mineral colloids such as birnessite, CO 2 is produced as a result of the decarboxylation of glycine , ring cleavage and subsequent decarboxylation of catechol (Majecher et al 2000) and pyrogallol (Wang and Huang 2000) and dehydration and subsequent decarboxylation of glucose (Jokic et al 2004) by birnessite.…”

Hardie, A. G., Dynes, J. J., Kozak, L. M. and Huang, P. M. 2009. Biomolecule-induced carbonate genesis in abiotic formation of humic substances in nature. Can. J. Soil Sci. 89: 445Á453. Most soil C sequestration research has focused on organic C stabilization, while carbonate precipitation has received little attention. Mineral colloids can accelerate abiotic humification reactions of biomolecules such as amino acids, sugars, and polyphenols, derived from the breakdown of biological residues and metabolites. During these reactions CO 2 is produced as a result of the oxidation of biomolecules. However, the biomolecule-induced formation of carbonate during abiotic humification remained to be uncovered. Here we demonstrate using X-ray diffraction, Fourier transform infrared spectroscopy and C K-edge and Mn L-edge near edge X-ray absorption fine structure spectroscopy that the Maillard reaction (glucose and glycine) and the integrated polyphenol-Maillard reaction pathway (catechol, glucose and glycine), in the presence of birnessite (d-MnO 2 ) produce MnCO 3 (rhodochrosite). Increasing the molar ratio of catechol to glucose and glycine dramatically hampered carbonate formation, which is attributed to the enhanced formation of humic polymers, which increased proton generation and perturbed rhodochrosite crystallization through Mn(II)-humic complexation in the reaction systems. Thus, rhodochrosite formation was a competing reaction with humic substance formation. Our findings are of fundamental significance in understanding the vital role of the nature and relative abundance of biomolecules in abiotic carbonate formation, which merits close attention in understanding and regulating C sequestration in natural environments. . Gene`se de carbonates sous l'effet des biomole´cules durant la formation abiotique des substances humiques dans la nature. Can. J. Soil Sci. 89: 445Á453. La majeure partie des recherches sur la se´questration du C dans le sol se concentrent sur la stabilisation du C et on s'est peu attarde´a`la pre´cipitation des carbonates. Or, les colloı¨des mine´raux peuvent acce´le´rer les re´actions d'humification abiotiques des biomole´cules tels les acides amine´s, les sucres et les polyphe´nols, issues de la de´composition des re´sidus biologiques et des me´tabolites.

Ne´anmoins, on ne sait toujours pas grand-chose de la formation des carbonates induite par les biomole´cules durant l'humification abiotique. Les auteurs ont recouru a`la spectroscopie XRD, FTIR et NEXAFS C au seuil K pour le C et au seuil L pour le Mn afin de montrer que la re´action de Maillard (glucose et glycine) et que la voie inte´grant les polyphe´nols et la re´action de Maillard (cate´chol, glucose et glycine) produisent du MnCO 3 (rhodochrosite) en pre´sence de birnessite (d-MnO 2 ). En augmentant le rapport molaire du cate´chol avec le glucose et la glycine, on entrave conside´rablement la formation de carbonates, ce qu'on attribue a`la synthe`se accrue de polyme...
