      Pathway Ecosystem in Madagascar.

AB  - The oxalate-carbonate pathway (OCP) is a biogeochemical process linking oxalate 
      oxidation and carbonate precipitation. Currently, this pathway is described as a 
      tripartite association involving oxalogenic plants, oxalogenic fungi, and 
      oxalotrophic bacteria. While the OCP has recently received increasing interest 
      given its potential for capturing carbon in soils, there are still many unknowns, 
      especially regarding the taxonomic and functional diversity of the fungi involved 
      in this pathway. To fill this gap, we described an active OCP site in Madagascar, 
      under the influence of the oxalogenic tree Tamarindus indica, and isolated, 
      identified, and characterized 50 fungal strains from the leaf litter. The fungal 
      diversity encompassed three phyla, namely Mucoromycota, Ascomycota, and 
      Basidiomycota, and 23 genera. Using various media, we further investigated their 
      functional potential. Most of the fungal strains produced siderophores and 
      presented proteolytic activities. The majority were also able to decompose 
      cellulose and xylan, but only a few were able to solubilize inorganic phosphate. 
      Regarding oxalate metabolism, several strains were able to produce calcium 
      oxalate crystals while others decomposed calcium oxalate. These results challenge 
      the current view of the OCP by indicating that fungi are both oxalate producers 
      and degraders. Moreover, they strengthen the importance of the role of fungi in 
      C, N, Ca, and Fe cycles.
