“…In addition, our cultivation-independent approach highlighted a significant enrichment of 16S rRNA gene sequences related to Burkholderia and Collimonas on obsidian and apatite. Moreover, several effective mineralweathering bacterial strains isolated in this study presented a strong homology of their 16S rRNA gene sequences with those of effective mineral-weathering bacterial strains previously isolated from the same experimental site in the rhizosphere or on mineral surfaces (33,68,69). Interestingly, significant positive correlations between the level of mineral dissolution and the relative abundance of 16S rRNA gene sequences assigned to the Betaproteobacteria class or to the Burkholderiales order were found for apatite particles incubated for 4 years in forest soil (33,34).…”

Although minerals represent important soil constituents, their impact on the diversity and structure of soil microbial communities remains poorly documented. In this study, pure mineral particles with various chemistries (i.e., obsidian, apatite, and calcite) were considered. Each mineral type was conditioned in mesh bags and incubated in soil below different tree stands (beech, coppice with standards, and Corsican pine) for 2.5 years to determine the relative impacts of mineralogy and mineral weatherability on the taxonomic and functional diversities of mineral-associated bacterial communities. After this incubation period, the minerals and the surrounding bulk soil were collected to determine mass loss and to perform soil analyses, enzymatic assays, and cultivation-dependent and -independent analyses. Notably, our 16S rRNA gene pyrosequencing analyses revealed that after the 2.5-year incubation period, the mineral-associated bacterial communities strongly differed from those of the surrounding bulk soil for all tree stands considered. When focusing only on minerals, our analyses showed that the bacterial communities associated with calcite, the less recalcitrant mineral type, significantly differed from those that colonized obsidian and apatite minerals. The cultivation-dependent analysis revealed significantly higher abundances of effective mineral-weathering bacteria on the most recalcitrant minerals (i.e., apatite and obsidian). Together, our data showed an enrichment of Betaproteobacteria and effective mineral-weathering bacteria related to the Burkholderia and Collimonas genera on the minerals, suggesting a key role for these taxa in mineral weathering and nutrient cycling in nutrient-poor forest ecosystems.IMPORTANCE Forests are usually developed on nutrient-poor and rocky soils, while nutrient-rich soils have been dedicated to agriculture. In this context, nutrient recycling and nutrient access are key processes in such environments. Deciphering how soil mineralogy influences the diversity, structure, and function of soil bacterial communities in relation to the soil conditions is crucial to better understanding the relative role of the soil bacterial communities in nutrient cycling and plant nutrition in nutrient-poor environments. The present study determined in detail the diversity and structure of bacterial communities associated with different mineral types incubated for 2.5 years in the soil under different tree species using cultivationdependent and -independent analyses. Our data showed an enrichment of specific bacterial taxa on the minerals, specifically on the most weathered minerals, suggesting that they play key roles in mineral weathering and nutrient cycling in nutrientpoor forest ecosystems.KEYWORDS mineral chemistry, bacterial communities, forest soil, mesh bags, mineral weatherability

The consumption of raw materials in the construction industry is a non-sustainable activity because in this process large amounts of natural resources are consumed. Moreover, Construction and Demolition Waste (CDW) represents around 50% of waste produced in the urban region of world. For example, in the Medellin Metropolitan Area (MMA), 10,400 t.day -1 of CDW are produced, of which only 9.7% is recycled. It is for this reason that CDW management is currently unsustainable and generates significant adverse environmental impacts. It is today acknowledged that this waste can be used as a by-product material for the production of recycled coarse aggregate, showing industrial applicability. However, CDW with small particle sizes (less than 4 mm that represents around 16% of this waste), do not have applicability in these processes. Therefore, it is necessary to reduce CDW volume dumped. An alternative to the final disposal of finer CDW is to use it to improve the physical and chemical properties of degraded soils and improve vegetation and ecosystem services. This paper evaluated the potential use of CDW as a source of nutrients for degraded soils after it was submitted to bioacidulation process by Aspergillus niger and Mortierella sp. Insoluble minerals such as quartz, calcite, wollastonite, albite, anatase and actinolite were found in the CDW by mineralogical and chemical characterization techniques. CDW mesh could improve the physical properties of degraded soils since these particles are similar in size to silt and clay. Furthermore, after CDW were bioacidulated an increased concentration of Ca 2+ were found, an essential nutrient for the growth and development of plants.

“…Microbes can accelerate mineral weathering reactions by producing organic and inorganic acids and metal-complexing ligands, changing redox conditions, or mediating formation of secondary mineral phases (3,10). Increasing evidence points to an important role played by bacteria in mineral weathering (1,11,12). In addition, there is a large body of knowledge concerning the distribution, community structure, and mineral weathering roles of bacterial communities in various environments, such as forest soils, tree rhizosphere and ectomycorrhizosphere environments, rock surfaces, and plant seeds (11,(13)(14)(15).…”

“…To date, the culture-dependent approach remains the only way to study the mineral weathering ability of bacterial communities (10,11,21,22). However, bacterial mineral weathering is really the result of a set of reactions (e.g., production of different corrosive acids, alkalis, and complexing agents), each of which is under the control of a different gene or gene complex, which are likely to be differently distributed among culturable and unculturable bacteria.…”

Bacteria play important roles in mineral weathering and soil formation. However, few reports of mineral weathering bacteria inhabiting subsurfaces of soil profiles have been published, raising the question of whether the subsurface weathering bacteria are fundamentally distinct from those in surface communities. To address this question, we isolated and characterized mineral weathering bacteria from two contrasting soil profiles with respect to their role in the weathering pattern evolution, their place in the community structure, and their depth-related changes in these two soil profiles. The effectiveness and pattern of bacterial mineral weathering were different in the two profiles and among the horizons within the respective profiles. The abundance of highly effective mineral weathering bacteria in the Changshu profile was significantly greater in the deepest horizon than in the upper horizons, whereas in the Yanting profile it was significantly greater in the upper horizons than in the deeper horizons. Most of the mineral weathering bacteria from the upper horizons of the Changshu profile and from the deeper horizons of the Yanting profile significantly acidified the culture media in the mineral weathering process. The proportion of siderophore-producing bacteria in the Changshu profile was similar in all horizons except in the Bg2 horizon, whereas the proportion of siderophore-producing bacteria in the Yanting profile was higher in the upper horizons than in the deeper horizons. Both profiles existed in different highly depth-specific culturable mineral weathering community structures. The depth-related changes in culturable weathering communities were primarily attributable to minor bacterial groups rather than to a change in the major population structure.
