“…Furthermore, at high salt concentrations and in liquid media, other bacteria precipitate monohydrocalcite, a mineral which was not detected among those precipitated by N. halobia. This could be regarded as further proof that bacteria play an active part in the precipitation of carbonates as indicated previously (Morita, 1980;Ferrer et al, 1988a,b;Rivadeneyra et al, 1991Rivadeneyra et al, , 1993Rivadeneyra et al, , 1994.…”

“…This is the tendency shown by the biominerals precipitated by N. halobia (Table 1) and di erentiates it from other moderately halophilic bacteria investigated in liquid media (Rivadeneyra et al, 1993(Rivadeneyra et al, , 1997, where the opposite occurs. Carbonate precipitation by N. halobia would thus be more similar to precipitation by inorganic processes.…”

“…Moderately halophilic bacteria can grow in a wide range of osmotic concentrations which makes them very useful for studying the e ect of salt concentration on their capacity to cause mineral precipitation. Some moderately halophilic bacteria have been reported to be capable of forming calcium carbonate precipitates (Ferrer et al, 1988a,b;Rivadeneyra et al, 1991Rivadeneyra et al, , 1993Rivadeneyra et al, , 1994. The results of these investigations showed that certain Chemosphere 41 (2000) 617±624 di erences exist between the bacteria, especially in terms of the mineralogy of the bioliths.…”

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

“…Although rapid in effect, some other methods such as the addition of cement or chemical fixatives are expensive ($30-$300/m 3 ) and destroy the future productivity of the soil (Cunningham et al, 1995). Microbially induced calcite precipitation (MICP) has been considered a novel solution for this problem, and several bacterial species have been already utilized for MICP (Kang et al, 2016;Rivadeneyra et al, 1993). MICP-based degradation of urea occurs through the ureolytic pathway, which produces ammonium ions as an energy source and leads to the alkalization of the surrounding environment (Whiffin et al, 2007).…”

Abandoned mine sites are frequently polluted with high concentrations of heavy metals. In this study, 25 calcite-forming bacteria were newly isolated from the soil of an abandoned metal mine in Korea. Based on their urease activity, calcite production, and resistance to copper toxicity, four isolates were selected and further identified by 16S rRNA gene sequencing. Among the isolates, Sporosarcina soli B-22 was selected for subsequent copper biosequestration studies, using the sand impermeability test by production of calcite and extracellular polymeric substance. High removal rates (61.8%) of copper were obtained when the sand samples were analyzed using an inductively coupled plasma-optical emission spectrometer following 72 h of incubation. Scanning electron microscopy showed that the copper carbonate precipitates had a diameter of approximately 5-10 m m m m mm. X-ray diffraction further confirmed the presence of copper carbonate and calcium carbonate crystals.

“…No obstante, los métodos microbiológicos convencionales presentan también desventajas, como son la pequeña proporción de los microorganismos presentes en una comunidad bacteriana que pueden ser cultivados en condiciones de laboratorio (Ward et al, 1990;Gonzalez & Saiz-Jiménez, 2004) y el relativo gran tamaño de muestra que se necesita para diseñar una buena estrategia de cultivo. Así, y a pesar de las numerosas evidencias y trabajos de investigación sobre el papel de las bacterias en la precipitación de carbonatos, el hecho de que gran parte de esas evidencias procedan de cultivos en laboratorios bajo condiciones ambientales diferentes a las del medio natural (Boquet et al, 1973;Rivadeneyra et al, 1994;Sanchez-Moral et al, 2003b;Baskar et al, 2006) hace que aún exista una gran controversia en la comunidad científica acerca de la relación directa entre microorganismos y fábricas minerales, y sobre las rutas metabólicas, el modo y las condiciones en las que se produce la precipitación de carbonatos (Castanier et al, 1999).…”

RESUMENLos microorganismos, en particular las bacterias, habitan en todos los ambientes posibles de la biosfera incluidos los ambientes subterráneos. Desempeñan un papel importante en procesos geológicos tales como la precipitación y disolución mineral, e influyen notablemente sobre los ciclos biogeoquími-cos de diferentes elementos. Hasta este momento, son relativamente pocos los estudios orientados a conocer el papel activo de los microorganismos, especialmente las bacterias, en la formación de espeleotemas, de manera que la implicación de la actividad microbiana en la precipitación y disolución mineral en ambientes kársticos es un tema aún sin resolver en geomicrobiología. Actualmente, no está del todo aclarada cuál es la interrelación entre los microorganismos y las fábricas minerales, ni el papel que juegan los microorganismos en la precipitación de carbonatos.Las cuevas son ambientes protegidos donde las fábricas microbianas pueden preservarse sin sufrir modificaciones diagenéticas importantes o destrucción, ofreciendo, por ello, un excelente entorno para estudiar los procesos de biomineralización (desde los propios microorganismos activos a sus depósitos minerales). Las nuevas tendencias en geomicrobiología se basan en la conjunción de diferentes metodologías (microclima, petrología, geoquímica, hidroquímica, microbiología, biología molecular) con un objetivo común: 1) determinar el papel de las diferentes comunidades microbianas que habitan los ambientes subterráneos en los procesos de transformación mineral; 2) identificar las propiedades físicas y químicas de las fases cristalinas bioinducidas, y 3) determinar las condiciones ambientales y las propiedades composicionales y texturales de los soportes rocosos naturales (biorreceptividad) que favorecen o inhiben el desarrollo de las comunidades microbianas.Palabras clave: comunidad microbiana, geomicrobiología, biorreceptividad, biomineralización, karst, cueva. ABSTRACT Microorganisms, particularly bacteria, inhabit all possible environments in the biosphere including subterranean ones. They play an important role in geological processes such as mineral precipitation and dissolution, and significantly influence biogeochemical cycles. At present, relatively few studies have focused on the active role of microorganisms, especially bacteria, in the formation of speleothems. Thus, the involvement of microbial activity in the formation of speleothems in caves is a geomicrobiological issue still to be solved. Today, the relationship between microorganisms and mineral fabrics and the role played by microorganisms in carbonate precipitation is unclear.The processes of carbonate deposit formation in caves offers an excellent scenario for research on biomineralization processes (from active microorganisms to their mineral deposits), because caves are protected environments where microbial fabrics can be preserved without extensive diagenetic modification or destruction. The new tendencies on geomicrobiological studies consist on applying different and multidiscipli...
