Biochar, Год журнала: 2023, Номер 5(1)

Опубликована: Окт. 5, 2023

Abstract Due to anthropogenic activities, heavy metal (HM) pollution in soils has increased, resulting severe ecological problems and posing a constant threat human health. Among various remediation methods, bacterial is relatively clean, efficient, minimally negative approach. However, agents face multiple environmental stresses, making them challenging achieve long-lasting stable restoration effects. To address this issue, supportive organic substances such as biochar can be added the soil with bacteria. According bibliometric studies, integrating bacteria extensively researched widely used for HM-contaminated remediation. By bacteria, metals remediated, conditions improved over time. Bacteria also better promote plant growth or contribute effectively phytoremediation processes when assisted by biochar. are still some distance away from large-scale use because of their high cost possible problems. Therefore, further discussion on interaction between integration approach, along efficiency friendliness, needed sustainable This paper discusses potential mechanisms biochar-bacteria-metal interactions, current advancements biochar-bacteria combinations treatment, application remediation, analyzes compares effect different ways feedstocks integrate Finally, future directions presented, evidence strategies improving commercialization implementation.

Improper disposal practices have caused environmental disruptions, possessing by heavy metal ions and radioactive elements in water soil, where the innovative sustainable remediation strategies are significantly imperative last few decades. Microbially induced carbonate precipitation (MICP) has emerged as a pioneering technology for remediating contaminated soil water. Generally, MICP employs urease-producing microorganisms to decompose urea (NH2CONH2) into ammonium (NH4+and carbon dioxide (CO2), thereby increasing pH levels inducing (CO32−), effectively removing remove contaminants. Nonetheless, intricate mechanism underlying mineralization poses significant challenge, constraining its application contaminants engineering, particularly context of prolonged leaching over time efficacy adverse conditions. This review provides comprehensive idea recent development examining metabolic pathways, mineral mechanisms, factors well providing future perspectives commercial utilization. The use ureolytic bacteria demonstrates cost-efficiency, compatibility, successful pollutant abatement tradition bioremediation techniques, bio-synthesis nanoparticles. limitations such large-scale application, elevated Ca2+levels groundwater, gradual contaminant release need be overcome. possible research directions technology, emphasizing potential conventional remediation, CO2 sequestration, bio-material synthesis, role reducing impact long-term economic benefits.

Impact of microbial processes on the safety of deep geological repositories for radioactive waste

Frontiers in Microbiology, Год журнала: 2023, Номер 14

Опубликована: Март 16, 2023

To date, the increasing production of radioactive waste due to extensive use nuclear power is becoming a global environmental concern for society. For this reason, many countries have been considering deep geological repositories (DGRs) safe disposal in near future. Several DGR designs chemically, physically, and geologically well characterized. However, less known about influence microbial processes safety these systems. The existence microorganisms materials selected their as barriers DGRs, including clay, cementitious materials, or crystalline rocks (e.g., granites), has previously reported. role that could play metal corrosion canisters containing waste, transformation clay minerals, gas production, mobility radionuclides characteristic such residues known. Among present selenium (Se), uranium (U), curium (Cm) are great interest. Se Cm common components spent fuel residues, mainly 79 isotope (half-life 3.27 × 10 5 years), 247 (half-life: 1.6 7 years) 248 3.5 6 isotopes, respectively. This review presents an up-to-date overview how microbes occurring surroundings may safety, with particular focus on radionuclide-microbial interactions. Consequently, paper will provide exhaustive understanding planned repositories, which turn might improve implementation efficiency.
