Study’s Novelty/Excerpt This study presents comprehensive overview of the roles various bacterial genera, including Alcaligens, Achromobacter, and Bacillus, in biosorption chromium from contaminated soils, highlighting specific factors influencing efficiency. It uniquely addresses optimization environmental conditions such as pH, temperature, nutrient availability to enhance large-scale processes, bridging gaps noted previous literature regarding scalability biosorption. Additionally, manuscript underscores necessity for further research biotechnology molecular engineering fully harness potential remediation, presenting a forward-looking perspective on advancing this bioremediation strategy. Full Abstract Chromium possesses detrimental effects health both plants animals. Biosorption is process where biological materials (bacteria, fungi, algae, or agricultural waste) are used remove pollutants sites. Conventional methods remediating heavy metal-contaminated excavation chemical treatment, expensive disruptive, making them less desirable. Factors efficiency promising approaches involving bacteria metals Chromium, lead, nickel, cadmium, arsenic, etc., soil. Some genera involved include Acinetobacter, Alteromonas, Arthrobacter, Burkholderia, Enterobacter, Flavobacterium, Pseudomonas. These can adsorb biotransform into toxic forms. concentration, surface compositions, metal ion characteristics, soil composition. Challenges associated with using biosorption, outlined literature, slowness fact that it may not be suitable application, even though many other authors have proven its applicability large scale. Also, key quality needed biosorbent must tolerating metals. Another area focus current optimizing conditions, availability, achieve more efficient at larger highlighted strategy Conclusively, has great use Chromium- realize potential, especially engineering.

Sunkiųjų metalų sąveikos su dirvožemio mikroorganizmais literatūros apžvalga

Опубликована: Июнь 13, 2024

Žmonių veikla (pramonė, žemės ūkis, kasyba, sąvartynai) susijusi su dirvožemio tarša sunkiaisiais metalais. Ši neigiamai veikia visus gyvus organizmus, įskaitant ir mikroorganizmus. Esant nedidelei sunkiųjų metalų koncentracijai mikroorganizmai gali pašalinti juos. Darbo tikslas: išanalizuoti sąveiką mikroorganizmais remiantis pateiktais moksliniais straipsniais. Tiriamas užterštumas įvairiais metalais, bet daugiausiai analizuojami kadmis, varis, švinas. Moksliniuose straipsniuose atliekami fitoremediacijos tyrimai, skirti ištirti ryšiui tarp mikroorganizmų naudojant augalus. Taip pat tyrimai dirvožemį, užterštą vykdant antropogeninę veiklą. Literatūroje aprašomi metalais užteršto kurie atskleidžia panaudojimo galimybes bei jų pokyčius laikui bėgant.
