As a result of worldwide industry, urbanization, and population growth, many harmful organic and inorganic pollutants have been introduced into the environment. With bioremediation, we can use fungi, bacteria, and plants - along with their secondary metabolites - to clean up areas that have been affected by industrial and commercial activities. Biotechnology in Environmental Remediation presents a thorough consideration of the most important biologically-based remediation methods in use today.
Environmental biotechnology is a more sustainable alternative to chemical and mechanical remediation methods, which explains the rapidly growing popularity of these techniques. This edited volume summarizes our current understanding of bioremediation approaches and presents research outcomes from a diverse selection of geographies and ecosystems. Chapters cover remediation techniques for pollutants affecting soil, water, air, and sediments, as well as tools for addressing these issues, including tools for assessment and monitoring.
Uniquely, Biotechnology in Environmental Remediation emphasizes the latest findings on the use of secondary metabolites in bioremediation. Other topics covered include chemical sustainability, nanotechnology, and biofuels. Readers will gain an understanding of issues including: - How biological organisms and their secondary metabolites are currently being used in environmental remediation projects worldwide - New applications for phytomolecules, lichens, nanoparticles, rhizobacteria, and other technologies, as well as future directions for bioremediation - The steps in the process of biotechnology-driven remediation, including detection, investigation, assessment, cleanup, redevelopment, and monitoring - Remediation of petroleum hydrocarbons, algal carbon sequestration, wastewater management, and the role of fatty acid and proteins in remediation
The investigations in this book provide important knowledge for researchers in biotechnology, ecology, environmental science, and related disciplines. Additionally, policymakers and NGOs with an interest in remediating environmental contaminants will gain valuable context. Biotechnology in Environmental Remediation is a foundation for future research on biotechnological interventions for a clean planet.
