“…The XRD data indicate the formation of magnesian calcite, characterized by a gradual decrease in peak intensity and an upward peak position shift (Figure 8b). Taking the characteristic peak corresponding to the (104) crystal face of calcite as the example, it can be seen that its position shifts toward the larger angles (29.400 • (control group) → 29.439 • → 29.480 • → 29.520 • → 29.578 • ) (Figure 8c), which is in agreement with the results reported by Wang [45]. The smaller radius of Mg 2+ compared to Ca 2+ results in a decrease in the cell parameters and an increase in the distance from the crystal lattice.…”

In order to apply precipitated calcium carbonate (PCC) in the detergent industry, its ability to deposit calcium ions in hard water is an important process. In this work, the calcium ion deposition in the presence of PCC from different sources is investigated to reveal the influencing factors and mechanism of nucleation and crystal growth of CaCO3. SEM, XRD, Malvern particle size analysis, and calcium electrodes are used to evaluate the effects of PCC morphology, saturation of Ca2+, and PCC additive amount on the deposition behavior of CaCO3. Through SEM and Malvern particle size analysis, it is found that the precipitation of calcium ions is obviously accelerated by PCC acting as seeds. Moreover, calcium ions are effectively adsorbed on (211) crystal facets, thus prismatic and scalenohedral PCC crystals exhibit better adsorption performance than irregular cubic PCC ones. In addition, XRD demonstrates that PCC reduces or even eliminates the formation of crystals such as vaterite, displaying high deposition capacity under complex water conditions (slightly acidic or highly alkaline pH, low magnesium ion concentration (<0.01 M), and temperatures of 0–60 °C), forming thermodynamically stable calcite in water, which significantly controls the instability of the washing process.

“…In addition to the strong absorption peaks of gypsum, dolomite and quartz, there are also some weaker absorption peaks indicating the possible presence of organic matter. The absorption bands in the 1000-1200 cm − 1 regions can be attributed to C-O-C, C -O or C -N derived from polysaccharides, glycosides and proteins (Schmitt and Flemming, 1998;Wang et al, 2022). These results were further confirmed by the XPS analysis results (Fig.…”

“…Thus, the halophilic V. harveyi seems to have played a role in the production of calcite and vaterite in our reaction media. V. harveyi is a well-known hyperhalophilic bacteria (Wang et al, 2022;Han et al, 2022) whose ability to precipitate calcite was reported under extreme halophilic conditions. According to our results, this bacterium seems to be able inducing MICP also in non-halophilic media.…”

Heavy metal contamination is listed among the most alarming threats to the environment and human health. The detrimental effects of heavy metals in the natural environment span from a reduction of biodiversity to toxic effects on marine life - through microplastic born heavy metals -, to impairment of microbial activity in the soil, and to detrimental effects on animal reproduction. A host of different chemical and biological technologies have been proposed to alleviate environmental contamination by heavy metals. Relatively less attention has been paid to the microbial precipitation of heavy metals, as a side mechanism of the most general process of microbially induced calcite precipitation (MICP). This process is currently receiving a great deal of interest from both a theoretical and practical standpoint, because of its possible practical applications in concrete healing and soil consolidation, and its importance in the more general framework of microbial induced mineral precipitation. In this study, we analyse the ability of the marine bacteria Vibrio harveyi in co-precipitating CaCO3 minerals, together with Cd, Cr, Pb, and Zn added in form of nitrates, from solutions containing CaCl2. The precipitated carbonatic minerals were a function of the different heavy metals present in the solution. The process of co-precipitation appears to be rather effective and fast, as the concentrations of the 4 heavy metals were reduced in 2 days by 97.2%, on average, in the solutions.
