“…Closer to environmental conditions, Cailleau et al (2009a) have proposed the involvement of naturally occurring nanofibrous polymers, such as cellulose. The nucleation of calcite on organic fibrous polymers has been demonstrated in laboratory experiments by several authors (Manoli et al, 1997;Dalas et al, 2000;Cailleau et al, 2009a;Ehrlich, 2010). Nanofibrous organic polymers are widespread features of biological systems as components of the cell walls of plants and fungi (Paul, 2007).…”

“…Their potential preservation in the environment under certain conditions makes them available to further participate in other soil solution mediated processes, such as acting as a template for the nucleation of secondary minerals. Indeed, both cellulose and chitin are known to be efficient templates for calcite nucleation (Manoli et al, 1997;Dalas et al, 2000;Giraud-Guille et al, 2004;Cailleau et al, 2005Cailleau et al, , 2009aCromme et al, 2007;Ehrlich, 2010). Therefore, both organopolymers can be considered as important templates for organomineralization processes.…”

Unravelling the enigmatic origin of calcitic nanofibres in soils and caves: purely physicochemical or biogenic processes?

Abstract. Calcitic nanofibres are ubiquitous habits of secondary calcium carbonate (CaCO 3 ) accumulations observed in calcareous vadose environments. Despite their widespread occurrence, the origin of these nanofeatures remains enigmatic. Three possible mechanisms fuel the debate: (i) purely physicochemical processes, (ii) mineralization of rod-shaped bacteria, and (iii) crystal precipitation on organic templates. Nanofibres can be either mineral (calcitic) or organic in nature. They are very often observed in association with needle fibre calcite (NFC), another typical secondary CaCO 3 habit in terrestrial environments. This association has contributed to some confusion between both habits, however they are truly two distinct calcitic features and their recurrent association is likely to be an important fact to help understanding the origin of nanofibres. In this paper the different hypotheses that currently exist to explain the origin of calcitic nanofibres are critically reviewed. In addition to this, a new hypothesis for the origin of nanofibres is proposed based on the fact that current knowledge attributes a fungal origin to NFC. As this feature and nanofibres are recurrently observed together, a possible fungal origin for nanofibres which are associated with NFC is investigated. Sequential enzymatic digestion of the fungal cell wall of selected fungal species demonstrates that the fungal cell wall can be a source of organic nanofibres. The obtained organic nanofibres show a striking morphological resemblance when compared to their natural counterparts, emphasizing a fungal origin for part of the organic nanofibres observed in association with NFC. It is further hypothesized that these organic nanofibres may act as templates for calcite nucleation in a biologically influenced mineralization process, generating calcitic nanofibres. This highlights the possible involvement of fungi in CaCO 3 biomineralization processes, a role still poorly documented. Moreover, on a global scale, the organomineralization of organic nanofibres into calcitic nanofibres might be an overlooked process deserving more attention to specify its impact on the biogeochemical cycles of both Ca and C.

“…However, the measurement of the pH of crystallizing solutions is essential for understanding CaCO 3 crystallization because pH decreases as crystallization proceeds. Another type of pH-stat assay is the constant composition method of Nancollas and co-workers (18)(19)(20). Usually, seed crystals of known surface area are added to metastable solutions.…”

“…The site-specific cell wall modification by pectin disassembly seems to be indispensable for continuous development of the cell wall sac. In addition, the occurrence of pectin-less fibers in the internal sac may be advantageous in production of CaCO 3 crystals, because there is a specific interaction between CaCO 3 and cellulose in vitro (Dalas et al 2000).…”

Ultrastructural and immunochemical features of the cell wall sac formed in mulberry (Morus alba) idioblasts

et al. 2008

A peculiar inward growth, named a "cell wall sac", formed in mulberry (Morus alba) idioblasts, is a subcellular site for production of calcium carbonate crystals. On the basis of ultrastructural observations, a fully expanded cell wall sac could be divided into two parts-an amorphous complex consisting of multi-layered compartments with multiple fibers originating from the innermost cell wall layer, and a peripheral plain matrix with fiber aggregates. Immunofluorescent localization showed that low and highly esterified pectin epitopes were detected at the early stages of development of the cell wall sac, followed by complete disappearance from the both parts of fully enlarged mature sac. In contrast, the xyloglucan epitope remained in the compartment complex; this was supported by the observation that the xyloglucan epitope labeled with immuno-gold particles is found on fibers in the complex part.
