Abstract

Bioremediation is a branch of biotechnology that employs the use of living organisms, like microalgae and fungi, in the removal of contaminants, pollutants, and toxins from soil, water, and other environments. The study was design to know and evaluate the efficiency of fungi to remediate two types of heavy metals (Pb and Cd), by using different concentrations (5, 15, 35, and 50ppm). Results revealed that the lowest applied dose (5ppm) of both tested heavy metals had the highest reduction percent by using two fungal stains Aspergillus niger and Candida albicans were remove lead by 85.6 and 84.2%, while for cadmium were 80 and 78.4% respectively. Statistically significant differences (P≤0.05) were observed between control and the treatments for both tested heavy metals. Highest heavy metals removal was found at the end of experiment (20 days).
黑曲霉和白色念珠菌对重金属的生物修复
生物修复是生物技术的一个分支,利用微藻和真菌等活生物体去除土壤、水和其他环境中的污染物、污染物和毒素。本研究旨在了解和评估真菌通过使用不同浓度(5、15、35和50ppm)修复两种重金属(Pb和Cd)的效率。结果表明,使用两种真菌菌株,最低施用剂量(5ppm)的两种重金属的还原率最高。黑曲霉和白色念珠菌对铅的去除率分别为85.6%和84.2%,而对镉的去除率则分别为80%和78.4%。在对照组和处理组之间观察到两种测试重金属的统计学显著差异(P≤0.05)。实验结束时(20天)重金属去除率最高。
