metadata.value: The present work focuses on the revealing the patterns of copper oxalates formation under the
  influence of lichens and fungi by combination of the results of field studies and model experiments.
  These findings create the scientific basis for the potential microbial technology applications (ore
  enrichment, monuments conservation, environment bioremediation, etc.). Copper oxalate moolooite
  Cu(C2O4)·H2O was discovered in saxicolous lichen Lecidea inops on the weathered chalcopyrite ore of
  Voronov Bor deposit (Central Karelia, Russia). Bioinspired syntheses of moolooite and wheatleyite
  Na2Cu(
  C2O4)2 2H2O
  with the participation of the microscopic fungi Aspergillus niger (active producer
  of oxalic acid) were carried out on weathered Cu-ore from the Voronov Bor deposit. It was shown
  that morphology of moolooite crystals is controlled both by the underlying rock and by the species
  composition of microorganisms. Iron ions (sourced from the underlying rock) in the crystallization
  medium inhibits the moolooite formation. The observed intensive dissolution of moolooite crystals
  are well explained by washing effect of the intratalline solutions which depends on repeatedly
  dehydration / rehydration cycles in the lichens. Joint interpretation of original and published data
  shows that moolooite along with other cooper oxalates are biominerals.
