“…To date, published studies have focused on the microscopic and chemical (Garcia-Valles and Vendrell, 2002, 2003) or on the microbial characterization of historical glass samples by culture-dependent techniques (Marvasi et al., 2009). Only a few published works have reported on the molecular characterization of historical glass samples (Rölleke et al., 1999; Schabereiter-Gurtner et al., 2001b; Carmona et al., 2006).…”

“…In addition, with the exception of some few works (Rölleke et al., 1999; Carmona et al., 2006; Marvasi et al., 2009) bacteria were thought not to be dominant colonizers of glass surfaces and not to play a relevant role in the observed deterioration phenomena. The results obtained in the present study clearly show that bacterial communities were more diverse than those of fungi and that the detected bacteria are phylogenetically related to well-known bacteria possessing metabolic activities able to produce the observed biodeterioration of the investigated glasses.…”

“…Glass biodeterioration is the result of metabolic activities of complex microbial communities composed mainly of fungi (Nagamuttu, 1967; Kaiser et al., 1996; Schabereiter-Gurtner et al., 2001b), bacteria (Rölleke et al., 1999; Marvasi et al., 2009), and lichens (Mellor, 1924). The organic residues present on historical glass, as dead microbial material, metabolites of autotrophic bacteria, animal faeces, and dust deposits, promote the microbial growth.…”

Bio-mediated processes for arsenic (As) uptake in calcite were investigated by means of X-ray Diffraction (XRD) and Xray Absorption Spectroscopy (XAS) coupled with X-ray Fluorescence measurements. The environmental bacterial strain Bacillus licheniformis BD5, sampled at the Bullicame Hot Springs (Viterbo, Central Italy), was used to synthesize calcite from As-enriched growth media. Both liquid and solid cultures were applied to simulate planktonic and biofilm community environments, respectively. Bacterial calcite samples cultured in liquid media had an As enrichment factor (Kd) 50 times higher than that from solid media. The XRD analysis revealed an elongation of the crystal lattice along the c axis (by 0.03 Å ) for biogenic calcite, which likely resulted from the substitution of larger arsenate for carbonate in the crystal. The XAS data also showed a clear difference in the oxidation state of sorbed As between bacterial and abiotic calcite. Abiotic chemical processes yielded predominantly As(V) uptake whereas bacterial precipitation processes led to the uptake of both As(III) and As(V). The presence of As(III) in bacterial calcite is proposed to result from subsequent reduction of arsenate to arsenite by bacterial activities. To the best of our knowledge, this is the first experimental observation of the incorporation of As(III) in the calcite crystal lattice, revealing a critical role of biochemical processes for the As cycling in nature.
