Summary: Biomineral formation is a common trait in soil Actinobacteria, including Streptomyces genus. In the presence of a heavy-metal-resistant Streptomyces mirabilis P16B-1, the formation of nickel-containing biominerals was investigated. It was found that biomineralization occurred both in solid and liquid media, with the minerals identified as either Mg-containing struvite or Ni-struvite. Precipitation of Ni-struvite reduced the concentration of nickel available in the medium, serving as an efficient mechanism for nickel tolerance. The contribution of a plasmid-encoded nickel efflux transporter in aiding biomineralization was discussed.

Summary: This study investigated the ability of a gram-negative bacterium (Enterobacter cloacae) and a gram-positive bacterium (Bacillus pumilus) to precipitate struvite crystals in synthetic municipal wastewater. Both organisms were able to precipitate struvite crystals with similar growth patterns, pH changes, and concentrations of ammonium and phosphate ions. The mechanism of struvite biomineralization was explained for both bacteria. The study further validated the results using real influent from an influent treatment plant, showing that Bacillus pumilus was able to precipitate crystals in real influent while Enterobacter cloacae was not. This study provides insights into bacterial biomineralization in wastewater and its potential for nutrient recovery and circularity in treatment plants, which can contribute to global food security.

Summary: Biomineralization of struvite for recovering dissolved organic phosphorus (DOP) from wastewater is a promising approach. This study used Shewanella oneidensis MR-1 with high organic P-mineralizing ability to mineralize struvite from Pb2+-bearing wastewaters. The results showed that MR-1 can efficiently mineralize struvite and form pyromorphite particles tightly associated with bacterial biomass, achieving concurrent phosphorus recovery and Pb2+ removal.

Summary: This study utilized biomineralization method to prepare a nickel-doped electrocatalyst, which exhibited outstanding catalytic activity in alkaline solution. It outperformed the commercial RuO2 catalyst due to the additional active sites introduced by nickel doping, facile electron transfer, enhanced conductivity, and wettability.

Summary: This study investigated the mechanisms of struvite production by biomineralization in municipal wastewater for five microorganisms, revealing different pathways for bio-struvite formation. Nutrient recovery through biomineralization has the potential to promote circularity within the wastewater industry, with various microorganisms showing promise for ortho-phosphate removal and bio-struvite generation.

Summary: Microbial communities in a former uranium mining site in Germany were screened for strains that can survive high salt and metal concentrations. These strains mainly rely on the formation of strontium- or cesium-struvite minerals to resist the toxic effects of metals and salt.

Summary: This study successfully converted human urine into fertilizer through chemical and biological mineralization, and evaluated their fertilizer potential. The synthesized struvite products showed slow release fertilizer characteristics and improved plant growth and seed yield of cowpea. It was found that struvite has the potential for long-term phosphate supply. The chemogenic synthesis route yielded higher struvite compared to the biogenic synthesis, but the latter is preferred for its eco-friendliness.

Summary: This study used an unbiased approach to investigate the key genes in magnetotactic bacteria (MTB) under different growth conditions. The results revealed the impact of growth conditions on the required genes for biomineralization and provided more understanding of the roles of MamT and other magnetosome gene island (MAI) genes in magnetosome formation.

Summary: When inducing bacterial-assisted mineralization of struvite by Shewanella oneidensis MR-1 in simulated Cr(VI)-bearing wastewaters, the yield and conversion efficiency were not significantly affected by Cr(VI), but surface pitting and roughening were observed. The struvite precipitated from the model wastewaters with 0.1 or 0.2 mM Cr(VI) met the regulatory standard of Cr content in fertilizers.

Summary: This study presented a quantitative, high-throughput urease activity assay based on a 96-well plate, which can be used for comparing and rapidly screening urease-producing bacteria. The assay revealed bacterial strains with high urease activity and showed the inhibitory effect of calcium on urease activity. The method has potential wide applications in environmental, civil, and medical research.

Summary: In this study, a multiple metal(loid) resistant bacterium Serratia sp. KUJM3 was found to be able to grow in contaminated wastewater and remove the metals by a certain percentage. It also had the ability to reduce arsenic and promote plant growth. Moreover, it was able to biomineralize struvite from human urine, which could be used as a fertilizer to enhance plant growth.

Summary: This study investigated the growth and bio-struvite production of Brevibacterium antiquum in mixed sludge culture. Alkaline fermentation was applied to enhance the phosphorus content of sludge, and pH 8 was found to be the most feasible condition. The presence of NaCl was found to decrease the growth rate and bio-struvite production of Brevibacterium antiquum.

Summary: The Reiche Zeche mine in Freiberg, Germany is known for its rich history of silver production and is now a famous research and education facility. The mine, established in the late 14th century, became part of the Bergakademie Freiberg in 1919. The mine contains various minerals such as galena, pyrite, sphalerite, arsenopyrite, and chalcopyrite. The acidic mine drainage in the mine has led to the development of microbial communities with low pH and high metal concentrations. The study investigated the community composition of these microbial habitats and found a diverse range of bacterial phyla, including iron-oxidizing bacteria. Overall, the presence of iron-oxidizing bacteria plays a crucial role in the investigated habitats.
