摘要

Heavy metal contamination of the environment is a serious issue, and more efficient and effective bioremediation techniques are needed. This review introduces current heavy metal bioremediation techniques, with focus on phytoremediation and microbial remediation, and recent developments in biochar and CRISPR-Cas9 technology. Phytoremediation employs the natural process of plants to accumulate and detoxify metals as an eco-friendly and sustainable technique. Microbial remediation by fungi and bacteria provides an additional approach through reduction, sequestration, and transformation of metals. Biochar as a high-carbon value-added pyrolytic biomass product improves soil quality, increases microbial activity, and adsorbs heavy metals, making bioremediation more effective. The discovery of CRISPR-Cas9 revolutionized gene engineering by allowing gene editing of plants and microbes to improve their metal tolerance and degradation. This review outlines recent developments, synergistic uses of biochar and CRISPR-Cas9, and how they might enhance phytoremediation and microbial remediation. By combining such novel technologies, strong, sustainable, and scalable solutions could be built for curbing heavy metal pollution and safeguarding environmental health.
