BIOSURFACTANT PROPERTIES AND ITS APPLICATION IN CHROMIUM REMOVAL: A REVIEW

FUDMA Journal of Sciences, Journal Year: 2025, Volume and Issue: 9(1), P. 273 - 287

Published: Jan. 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, Journal Year: 2025, Volume and Issue: unknown

Published: April 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.

Journal of Experimental Biology and Agricultural Sciences, Journal Year: 2025, Volume and Issue: 13(2), P. 239 - 257

Published: May 5, 2025

Microbial fuel cells (MFCs) present a promising green technology for wastewater treatment while simultaneously generating power. However, MFCs to be sustainable and scalable, they require significant technological operational improvements. This study aimed optimize the MFC process using Response Surface Methodology (RSM), which integrates modeling techniques, optimization methodologies, experimental design, analysis. RSM was applied evaluate interactions among three independent variables: working volume of wastewater, buffer's pH, bacterial consortia's inoculum size. Double-chambered were inoculated with various strains, including Pseudomonas stutzeri, Microbacterium algeriense, Bacillus stratosphericus. The results indicated that performance significantly influenced by between (i) buffer (ii) size, (iii) pH findings identified optimal conditions power generation hexavalent chromium (Cr6+) reduction as approximately 80% 6.9, 26% size consortia.
