Hexavalent chromium removal from the environment remains a crucial worldwide challenge. To address this issue, microbiological approaches are amongst straightforward strategies that rely mainly on bacteria's and fungi's survival mechanisms upon exposure to toxic metals, such as reduction, efflux system, uptake, biosorption. In work, scanning electron microscopy, energy-dispersive X-ray spectrophotometry, Fourier transform infrared spectroscopy, zeta potential measurements were used investigate ability of adsorption by

Hexavalent chromium (Cr(VI)) poses a significant ecological threat due to environmental pollution. The urgent need for an economically viable solution remove Cr(VI) and restore balance is evident. This study explores the adsorption isotherms of uptake by newly isolated B. bassiana SSR5 dead fungal biomass. batch experiments, conducted under controlled pH temperature conditions, reveal that biomass from has outstanding ability adsorb Cr(VI). optimal occurs at levels 1 ≤1.5, achieving maximum capacity 113.2 mg per gram dry weight initial concentration 300 mg/L. strongly influenced pH, with peak values noted 1.0. Conversely, variations show minimal impact on capacity. All exhibit strong correlation standard Langmuir equation, indicating monolayer mechanism. kinetic profile illustrates rapid process, equilibrium within 30 min, suggesting involvement chemisorption. process primarily involves ion exchange electrostatic interactions between positively charged sites negatively ions lower levels, facilitating reduction Cr(III) enhancing adsorption. underscores potential as effective biosorbent removal wastewater tannery effluent. intriguing mechanism effect conversion cell wall warrant further exploration.
