“…The inhibitory e ect of magnesium ions on carbonate precipitation is considerably weaker in moderately halophilic bacteria than in non-halophilic bacteria (Ferrer et al, 1988a;Rivadeneyra et al, 1994). In our study, the slight di erence in the amount of crystal formation between 2.5% and 7.5% salt concentration and the fact that there was still precipitation at 15% tend to con®rm the previous observation.…”

“…However, the quantities of aragonite tended to decrease with increasing incubation time. Ferrer et al (1988a) suggest that the ionic strength of the medium a ects the di erent groups of moderately halophilic microorganisms in a di erent way. Our results con®rm these observations, since, although magnesium calcite, aragonite and dolomite are also precipitated by other bacteria under similar conditions, the percentages are very di erent.…”

Precipitation of carbonates by Nesterenkonia halobia in liquid media

We investigated the precipitation of carbonates by Nesterenkonia halobia in a liquid medium at di erent concentrations of salts and incubation times. N. halobia only produced crystals at salt concentrations of 2.5%, 7.5% and 15%. At 20% salt concentration no crystal formation was observed. Calcite, aragonite and dolomite were precipitated in di erent quantities, depending on the salinity of the medium and incubation time. Scanning and transmission electron microscopy, microanalysis and electron di raction were all used to study in detail the morphology, composition and internal structure of the bioliths. We propose a mechanism for biolith formation involving both biological and inorganic processes. Ó

“…The isolates studied were able to precipitate carbonates under the chosen experimental conditions at 30°C, and the amount of precipitation increased with incubation time. The optimum temperature for bacterial carbonate precipitation has been established to be in a range between 22°C and 32°C (24,48,52,55). The relationship between the extent of carbonate precipitation and incubation time could not be related to an increase in biomass.…”

“…Carbonate precipitation by bacteria, referred to as biocalcification, has been widely studied in the saline aquatic environment by Lipman (34), Morita (35), and Novitsky (37); in fresh and saline soil by Parraga et al (39), Ferrer et al (24,25), Rivadeneyra et al (48,52,53,54,55), and Braissant et al (10); and in freshwater environments by Danielli and Edington (17), Cacchio et al (12,13), and Baskar et al (5). The ability of bacteria to precipitate carbonate crystals has been described by Boquet et al (9) as a process that is widely spread among different bacterial species.…”

Bacterial carbonate precipitation is known to be a natural phenomenon associated with a wide range of bacterial species. Recently, the ability of bacteria to produce carbonates has been studied for its value in the conservation of limestone monuments and concrete. This paper describes investigations of carbonate crystals precipitated by freshwater bacteria by means of histological (Loeffler's methylene blue and alcian blue-periodic acid-Schiff stain) and fluorescence (CTC [5-cyano-2,3-ditolyl tetrazolium chloride]) stains, determination of cell viability inside carbonate crystals, and pore size reduction in limestone by image analysis. Carbonate crystals were found to be composed of bacteria embedded in a matrix of neutral and acid polysaccharides. Cell viability inside the carbonate crystals decreased with time. On stone, bacteria were found to form carbonate crystals, with only a few bacteria remaining as isolated cells or as cell aggregates. Pore size was reduced by about 50%, but no blockage was detected. Taken together, the results of this research provide some reassurance to conservators that biocalcification by bacteria could be a safe consolidation tool in a restoration strategy for building stone conservation.

“…Some moderately halophilic bacteria have previously been reported to be capable of forming CaCO 3 precipitates [14][15][16][17]. The results of these studies suggest that different species differ in their response to increasing salinity not only by varying the crystalline type of CaCO 3 formed, but also in the extent of crystal formation.…”

Calcium carbonate precipitation by 63 strains of moderately halophilic bacteria (Vibrio spp.) isolated from water of a saltern pond has been studied, taking into account the influence of salinity and temperature on the quantity and type of crystals precipitated. The bacteria formed crystals under all the conditions tested. All the crystals were magnesium calcite, with a variable Mg content, depending upon the medium provided. No aragonite was detected, even in a media with high Mg contents. Whether these microorganisms play an active role in precipitation is discussed, as well as the possibility that they may contribute to CaCO 3 precipitation in their natural habitats.
