SummaryPermanent storage of anthropogenic CO 2 in deep geologic formations is being considered as a means to reduce the concentration of atmospheric CO 2 and thus its contribution to global climate change. To assure safe and effective geologic sequestration, numerous studies have been completed regarding the extent to which CO 2 migrates within geologic formations, and what physical and geochemical changes occur in these formations when CO 2 is injected. Sophisticated, computerized reservoir simulations are used as part of field site and laboratory CO 2 sequestration studies. These simulations use coupled multiphase flow-reactive chemical transport models and/or standalone (i.e., no coupled fluid transport) geochemical models to calculate gas solubility, aqueous complexation, reduction/oxidation (redox), and/or mineral solubility reactions related to CO 2 injection and sequestration.Thermodynamic data are critical inputs to modeling geochemical processes. The adequacy of thermodynamic data for carbonate compounds has been identified as an important data requirement for the successful application of these geochemical reaction models to CO 2 sequestration. Therefore, a review was completed of thermodynamic data for CO 2 gas and carbonate aqueous species and minerals present in published data compilations and databases used in geochemical reaction models. Published studies that describe mineralogical analyses from CO 2 sequestration field and natural analogue sites and laboratory studies were also reviewed to identify specific carbonate minerals that are important to CO 2 sequestration reactions and therefore require thermodynamic data.The results of the literature review (Section 5.0) indicate that an extensive thermodynamic database exists for CO 2 and CH 4 gases, carbonate aqueous species, and carbonate minerals. Values of ∆ f G 298° and/or log K r,298° are available for essentially all of these compounds. However, log K r,T° or heat capacity values at temperatures above 298 K exist for less than approximately one-third of these compounds. Because the temperatures of host formations that will be used for CO 2 injection and sequestration will be at temperatures in the range of 50ºC to 100ºC or greater, the lack of high-temperature thermodynamic values for key carbonate compounds, especially minerals, will impact the accuracy of some modeling calculations.In comparison to the available thermodynamic data for carbonate minerals, only a small number of carbonate minerals have been described in published studies as actually being present in the host rock formations at CO 2 injection test sites or natural analogue sites, reaction products of CO 2 injection/ intrusion into a host formation, or as mineral reactants or products of laboratory CO 2 fluid-rock and -mineral experiments. Except for a few carbonate solid-solution minerals (ferroan and magnesian carbonates and ferroan dolomite), thermodynamic data are available for the pure carbonate minerals identified in these natural analogue site and fluid-rock and -mineral...

“…Besides that, the same strain was used in another study [23] that performed an analysis in vitro of the bioprecipitation of calcium carbonate by pH change during biofilm formation. The authors found that the B. subtilis AP91 were able to precipitate crystals of CaCO3 with the same morphology as other researches [11,[36][37][38][39][40]. Other investigators conducted the studies in the same way, first studying whether the bacterium has the ability to precipitate CaCO3 and in the sequence analyzing how that addition would behave in the cement matrix [9,41].…”

This study aimed to analyze the performance of two concrete mixtures with the addition of B. subtilis spores regarding their capacity of filling cracks during the curing time, evaluating whether the addition can influence the compressive strength of the concrete. For so, six concrete mixtures were studied divided in two mix compositions: 1:1:2 and 1:2:3 (cement: sand: gravel) with w/c of 0.33 and 0.45, respectively. For each composition were added concentrations of 0, 0.3x10 8 or 1.2x10 8 of B. subtilis spores/mL. The results showed that all the samples with spores addition presented crystals precipitation, possibly calcium carbonate, that visually filled the cracks. However, more studies of microstructural analysis should be conducted to prove that the cracks were closed. The compressive strength presented satisfactory results, because the addition of 1.2x10 8 spores/mL did not present significant differences in compressive strength at probability level of 5%, when compared to the reference concrete.Keywords: bioconcrete; concrete with addition of spores; Bacillus subtilis; crack filling; cracks.Relleno de fisuras en concreto por la adición de esporas de Bacilos subtilis -Estudio preliminar ResumenEste estudio tiene como objetivo analizar el desempeño de dos composiciones de hormigón con adición de esporas de B. sutilis con relación a su capacidad de relleno de fisuras durante el periodo de cura, evaluando la influencia de la adición en la resistencia a compresión. Para ello han sido estudiadas seis composiciones de hormigón, divididas en dos dosificaciones: 1:1:2 y 1:2:3 (cemento: árido fino: grava) en peso, con relación a/c de 0,33 y 0,45. Para cada una de las mezclas se utilizaran concentraciones de 0, 0.3x10 8 or 1.2x10 8 de esporas de B. sutilis/mL. Los resultados obtenidos han demostrado que todas las muestras con adición de esporas presentaron precipitación de cristales, posiblemente carbonato de calcio, que fue visualizado en las fisuras. Más estudios microestructurales deberán ser realizados para comprobar que de hecho ocurrió el relleno de las fisuras. La resistencia a compresión presentó resultados satisfactorios, pues no hubo diferencias significativas en relación al hormigón de referencia, a nivel de 5% de probabilidad.Palabras clave: biohormigón; hormigón con adición de esporas; Bacilos subtilis; relleno de fisuras; fisuras.

“…(1) The formation of miscellaneous crystalline carbonates (e.g., aragonite, Mg-rich or Mg-low calcite, dolomite) may result from extracellular precipitation [72,[75][76][77][78]. In this case, negatively charged groups exposed at the surface of the cell and/or of exopolymeric substances (EPS) act as mineral nucleation sites for carbonate precipitation, so that organic matter is intimately associated with carbonate minerals.…”

Evidencing ancient interspecific associations in the fossil record may be challenging, particularly when bacterial organisms have most likely been degraded during diagenesis. Yet, documenting ancient interspecific associations may provide valuable insights into paleoenvironmental conditions and paleocommunities. Here, we report the multiscale characterization of contemporary and fossilized calcifying bacterial colonies found on contemporary shrimps from Mexico (La Paz Bay) and on 160-Ma old fossilized decapods (shrimps) from the Lagerstätte of La Voulte-sur-Rhône (France), respectively. We document the fine scale morphology, the inorganic composition and the organic signatures of both the contemporary and fossilized structures formed by these bacterial colonies using a combination of electron microscopies and synchrotron-based scanning transmission X-ray microscopy. In addition to discussing the mechanisms of carbonate precipitation by such bacterial colonies, the present study illustrates the degradation of bacterial remains occurring during diagenesis.
