famous quotes “Silver or lead?” (silver or lead) could also have been spoken by bacteria of the genus Klebsiella. According to findings made by a team of scientists from the Department of Chemical and Environmental Engineering at the University of Jaén, this microbe can remove silver or lead. . waste waterwhile generating a powerful antibacterial Agents decontaminate it at the same time.
The results of this study could open a very attractive door to the development of Water treatment biofilterDuring a chemical process described by Spanish researchers, this bacterium is able to remove heavy metals without creating hazardous waste problems. genus Cribusera. 3S1 In such situations, it can be very useful in sewage treatment plants as it eliminates the need for specific treatment procedures for heavy metal-contaminated water and reduces costs.
Research study
Analyzed by experts 48 types of microorganisms (Fungal, Yeast, Bacteria) To find the most suitable species to meet your goals: Silver It is possible while avoiding pouring additional hazardous substances into the water during the treatment process. The results, published in the Journal of Hazardous Materials, show that after laboratory testing, the organisms that best fit the requirements are: Cribcella sp. 3S1.
This bacterium belongs to the same family as the causative bacterium. pneumoniaalthough it does not cause pathogenic responses in humans or other species and is naturally present in the environment.
Research studies conducted by Spanish scientists have confirmed that this organism can holding silver Via two different procedures. on the other hand, biological absorptionat the surface level, bacteria can capture silver without expending energy. bioaccumulationat the intracellular level, collects toxic substances from the environment and stores them internally for neutralization or post-elimination.
This finding is added to the results obtained in previous research Conducted by the same team. That study, published in the Journal of Industrial and Engineering Chemistry, demonstrated the ability of bacteria in wastewater treatment procedures, leading to biosorption by bacteria his biofilms attached to low-cost ceramic his bearings.
Silver chloride, an ally of pollution
This bacterium can also produce silver chloride, a compound widely used as an antibacterial agent. therefore, Cribcella can be a highly demanded supply of resources in Biomedical and nanotechnology Thanks to its optical, electrical, mechanical and structural properties, it is used in various industries.
At the same time, this organism has the potential to become a cheaper and more effective biotherapeutic than those currently in use. The presence of heavy metals in water destined for human consumption is a concern for institutions, so a new line of research is opening up.
In this regard, the development of new water treatment technologies and methods could be an important aspect for providing solutions to this problem.
