Role of Biotechnology in Remediation of Cadmium from Contaminated Site

The growing risk of soil cadmium (Cd) pollution calls for creative approaches to environmental remediation. The critical role that biotechnology plays in mitigating Cd pollution and cleaning up contaminated places is examined in this chapter. A thorough understanding of several biotechnology techniques, such as genetic engineering, phytoremediation, and microbial remediation, is given. The ability of microorganisms, including fungus and bacteria, to remove, change, or immobilize Cd from soil matrices is being investigated. This chapter emphasizes how important plants are for collecting and storing Cd, particularly hyperaccumulators, which help restore damaged ecosystems. Recent advancements in genetic engineering have led to the creation of plant and species variants that are tolerant of cadmium (Cd), enhancing their effectiveness in environmental cleanup procedures. The difficulties and constraints posed by biotechnology applications are discussed, taking into account ecological elements, site-specific characteristics, and regulatory requirements. This chapter promotes integrated strategies that combine traditional remediation techniques with biotechnology to achieve effective and sustainable Cd remediation. To sum up, this chapter is an invaluable tool for scholars, environmental scientists, and decision-makers. It supports ongoing initiatives to preserve ecosystems, advance sustainable agriculture, and defend human health from Cd pollution by investigating environmentally beneficial tactics. The application of biotechnology presents viable paths toward the creation of efficient and ecologically responsible ways to lessen the effects of Cd pollution.
