Special Issue Information

Dear Colleagues,

The global cycling of organic matter and elements is driven to a great extent by microorganisms with the ability to exchange electrons with extracellular minerals. The integration of mineral and microorganism is critical not only to the mechanistic understanding of extracellular electron transfer processes but also advances of biotechnological applications in the bioremediation of redox-amendable environmental contaminants and bioenergy.

This Special Issue aims to bring together studies in the areas of geomicrobiology and biogeochemistry, including the disposal of hazardous waste, the treatment of acid mine drainage and waste water, the capture of carbon dioxide, the health effects of minerals, and mineral–microbe interactions, among others.

Organic pollution is one of the main sources of environmental pollution, which poses a serious threat to the ecological environment and human health. In this study, we synthesized a composite material consisting of biochar-supported magnetite nanoparticles (Bio/MNs) and collaborated with Pseudomonas aeruginosa PAO1 (P. aeruginosa PAO1) to conduct a bio-chemical composite remediation approach for organic pollution. The results of the scanning electron microscope (SEM) and X-ray diffractometer (XRD) show that Bio/MNs composites have been prepared successfully. Under light conditions, the highest removal rate of organic pollution by Bio/MNs synergistic P. aeruginosa PAO1 reached 81.5%. Gradient experiments revealed a direct correlation between the removal rate of organic pollution and the dosage of P. aeruginosa PAO1, as well as the input of Bio/MNs, within a specific range. Moreover, due to the positively charged nature of organic pollution, its maximum removal rate reaches 98.6% at pH = 11, exhibiting a 1.76-fold increase compared to that at pH = 3. The experimental results show that the collaboration between Bio/MNs and P. aeruginosa PAO1 expedited the electron transfer rate and increased the generation of ·OH and O2−, consequently facilitating the efficient degradation of organic pollutants. These findings inspire Bio/MNs collaborative microorganisms for providing new methods for the green and sustainable removal of organic pollutants. Full article

Microbial fuel cells (MFC) have considerable potential in the field of energy production and pollutant treatment. However, a low power generation performance remains a significant bottleneck for MFCs. Biochar and anatase are anticipated to emerge as novel cathode catalytic materials due to their distinctive physicochemical properties and functional group architectures. In this study, biochar was utilized as a support for an anatase cathode to investigate the enhancement of the MFC power generation performance and its environmental impact. The results of the SEM and XPS experiments showed that the biochar-supported anatase composites were successfully prepared. Using the new cathode catalyst, the maximum current density and power density of the MFC reached 164 mA/m2 and 10.34 W/m2, respectively, which increased by 133% and 265% compared to a graphite cathode (70.51 mA/m2 and 2.83 W/m2). The degradation efficiency of Cr (VI) was 3.1 times higher in the biochar-supported anatase MFC than in the graphite cathode. The concentration and pH gradient experiments revealed that the degradation efficiency of Cr (VI) was 97.05% at an initial concentration of 10 mg/L, whereas a pH value of two resulted in a degradation efficiency of 94.275%. The biochar-supported anatase composites avoided anatase agglomeration and provided more active sites, thus accelerating the cathode electron transfer. In this study, natural anatase and biochar were ingeniously combined to fabricate a green and efficient electrode catalyst, offering a novel approach for the preparation of high-performance positive catalysts as well as a sustainable, economical, and environmentally friendly method for Cr (VI) removal in aqueous solutions.

Electrolytic manganese residue (EMR) contains a large number of soluble manganese ions and ammonia nitrogen, which seriously endangers the surrounding environment. Solidifying manganese and removing nitrogen has become the primary method for controlling EMR. In this study, an EMR stacking yard in Guangxi was used as a study site to study the solidification of soluble manganese ions and the removal of ammonia nitrogen by mixed bacteria under natural conditions. Further, Illumina MiSeq high-throughput sequencing technology was used to analyze the difference in microbial community structure and function. The results showed that the solidification rate of soluble manganese ions in the remediation area reached more than 99%, and the removal effect of ammonia nitrogen in EMR was obvious. The mechanism showed that manganese in EMR was solidified into MnS. High-throughput sequencing results showed that the abundance of sulfate-reducing bacteria in the remediation area was significantly higher than that in the control area. The functional groups predicted by the FAPROTAX database showed the functional groups related to N and S reduction increased significantly in the remediation area, while the functional groups related to N and S oxidation decreased. Microorganisms in the remediation area promoted the circulation of N and S elements, and the vegetation on the surface of the residue field in the remediation area was also restored. Full article
