FUDMA Journal of Sciences, Год журнала: 2025, Номер 9(1), С. 273 - 287

Опубликована: Янв. 31, 2025

Chromium contamination primarily originates from anthropogenic activities such as industrial discharges, mining operations, and the improper disposal of chromium-containing products, leading to its infiltration into soil groundwater. The persistence chromium in environment poses severe ecological health risks, including bioaccumulation aquatic organisms adverse effects on plant growth microbes. Human exposure through contaminated water or occupational settings is linked respiratory problems, skin disorders, heightened cancer risk. Addressing these challenges necessitates sustainable remediation approaches, highlighting potential biosurfactants eco-friendly alternatives conventional methods. This review was aimed provide an overview different properties application removal, covering key aspects introduction future perspectives. Biosurfactants microbial-derived surface-active agents, exhibit that make them highly effective reducing contamination. Their biodegradability, low toxicity, renewable production ensure minimal environmental impact. Moreover, their amphiphilic nature enhances bioavailability, facilitating microbial uptake reduction. Certain chelate metal ions, preventing migration secondary contamination, while synergistic interactions with microorganisms improve efficiency. By supporting transformation toxic Cr (VI) less harmful (III) promoting precipitation insoluble compounds, offer a versatile solution for mitigating pollution.

Biofilm Formation and Detoxification of Hexavalent Chromium by Bacillus subtilis: A Sustainable Approach to Bioremediation

Journal of Basic Microbiology, Год журнала: 2025, Номер unknown

Опубликована: Апрель 24, 2025

ABSTRACT Hexavalent chromium [Cr(VI)] is a toxic environmental pollutant, primarily generated by industrial processes, posing significant risk to biota. Effective detoxification of Cr(VI) necessary before discharge. This study focused on the tolerance and potential an isolated Bacillus subtilis strain KCBA07C10, along with effects stress its biofilm formation, application in bioremediation. The bacterial from treated textile effluent, was subjected growth studies Cr(VI)‐supplemented media low carbon source. Detoxification assessed through total Cr removal analyses, while formation evaluated using spectrophotometric assays scanning electron microscopy. Results revealed that B. KCBA07C10 tolerates high concentrations (> 16.0 mg/L) achieves via bioreduction, removing nearly 88% even under nutrient‐limited conditions. These findings highlight strain's for Furthermore, quantitative demonstrated positive correlation between exposure ( p = 0.009, α 0.05), suggesting adaptive defense mechanism. highlights as eco‐friendly agent bioremediation applications.

This study investigates the bacteriological properties and overall quality of urban water supplies, particularly desalinated used in households at Al-Darb College. The is derived from desalination facilities Al-Shaqiq delivered through pipelines across southern Saudi Arabia, covering regions such as Jazan, Ad Darb, Abha. Novel nano zero-valent iron nanoparticles, MS-ZVI@PP, were synthesized with extracts Moringa oleifera seeds pomegranate peels immobilized sodium alginate beads combating bacterial contamination. Characterization by X-ray diffraction Transmission Electron Microscopy confirmed successful formation crystallites nZVI typical particle diameters between 18.34 to 22.4 nm. Fourier Transform Infrared Spectroscopy detected existence several functional groups C = C, O–H, C–H, O, C–O–C, related synthesis. Kinetic isotherm studies showed that pseudo-second-order model Freundlich best fit represents adhesion mechanism.
