Cr(VI) Reduction and Fe(II) Regeneration by Penicillium oxalicum SL2-Enhanced Nanoscale Zero-Valent Iron

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(30), P. 11313 - 11324

Nanoscale zero-valent iron (nZVI) faces significant challenges in Cr(VI) remediation through aggregation and passivation. This study identified a Cr(VI)-resistant filamentous fungus (Penicillium oxalicum SL2) for nZVI activation elucidated the synergistic mechanism chromium remediation. P. SL2 synergistically effectively removed Cr(VI), mainly by extracellular nonenzymatic reduction (89.1%). exhibited marked precipitate solubilization Fe(II) regeneration capabilities. The existence of Fe(II)–Cr(V)-oxalate complex (HCrFeC4O9) indicated that addition to directly reducing ions generated stimulated organic acids secreted SL2. RNA sequencing bioinformatics analysis revealed inhibited phosphate transport channels suppress transport, facilitated siderophore store Fe, activated glyoxylate cycle survive harsh environments, enhanced acid riboflavin secretion reduce Cr(VI). exposure also antioxidative system, promoting catalase activity maintaining intracellular thiol/disulfide balance. Cr(VI)/Fe(III) reductases played crucial roles iron, while decreased cellular oxidative stress alleviated toxicity Overall, SL2–nZVI system is promising approach regenerating

Potential Fungal-bacterial Biofilm for Bioremediation Polluted Soils of Chromium and Its Impact on Maize Growth

Yüzüncü Yıl Üniversitesi Tarım Bilimleri Dergisi, Journal Year: 2025, Volume and Issue: 35(1), P. 9 - 22

Published: March 27, 2025

Recently, biofilm has emerged as a notable agent in bioremediation. The present study was conducted to determine the potential of microbes described forming fungal-bacterial (FBB) bioremediation for chromium-contaminated soil. Parameters observed include total chromium concentration soil, Zea mays growth, tissue, and its effects on microbial populations. commenced with formation assays pot experiments greenhouse using combinations chemical fertilizer (CF) mays. This research employed Completely Randomized Design (CRD) five treatments four replications: A (100% CF), B (75% CF + 25% FBB), C (50% 50% D (25% 75% E FBB). results indicate that all could reduce below threshold limit (2.5 mg kg-1), lowest found at 1.25 kg-1. FBB alone or combination did not enhance growth. Treatment exhibited plant height, crown dry weight, root weight sequentially 20.31%, 84.10%, 76.15% lower than treatment A. increase accumulation plants, having highest roots, 15.47 µg g-1 15.59 g-1. Application 100% increased soil bacterial population by 44.02% compared In conclusion, microorganisms identified can form serve agents enhancing heavy metal plants (phytoextraction).

Potential Applications of an Exopolysaccharide Produced by Bacillus xiamenensis RT6 Isolated from an Acidic Environment

Polymers, Journal Year: 2022, Volume and Issue: 14(18), P. 3918 - 3918

Published: Sept. 19, 2022

The Bacillus xiamenensis RT6 strain was isolated and identified by morphological, biochemical molecular tests from an extreme acidic environment, Rio Tinto (Huelva). Optimisation for exopolysaccharide (EPS) production in different culture media determined that the best medium a minimal with glucose as only carbon source. exopolymer (EPSt) produced characterised using techniques (GC-MS, HPLC/MSMS, ATR-FTIR, TGA, DSC). weight of EPSt estimated. results showed average approximately 2.71 × 104 Da made up heteropolysaccharide composed (60%), mannose (20%) galactose (20%). antioxidant capabilities significantly improved cell viability. Metal chelation could reduce concentration transition metals such iron at highest concentrations tested. Finally, emulsification study able to emulsify natural polysaccharide oils, reaching 80% efficiency (olive sesame oil), good candidate substitution most polluting emulsifiers. found be suitable pharmaceutical industrial applications.
