This book, Petroleum Nanobiotechnology: Modern Applications for a Sustainable Future, explores the unique fusion of biotechnology and nanotechnology as applied to the different sectors of the oil and gas industry. It is a concise resource on the most recent and most up-to-date bottom-up fabrication techniques in petroleum nanobiotechnology, covering the advantages of biofabrication over chemical or physical techniques from the point of being more cost-effective, ecofriendly, biocompatibly superior, and highly stable.The volume covers the important topic of microbial and phytosynthesis of metal and metal oxide nanoparticles. The key applications discussed here include the application of these nanoparticles in different sectors of the oil and gas industry, with special emphasis on antimicrobial applications, reduction of environmental pollutants, and bio-upgrading of petroleum and its fractions. The discussion of each application is augmented with a critical review of the potential for continued development.The book first provides an overview of petroleum microbiology and nanotechnology and proceeds to consider phytosynthesis of metal nanoparticles, microbial synthesis of metal nanoparticles, biosynthesis of metal oxide nanoparticles, nanobiotechnology and mitigation of microbial-influenced corrosion in petroleum industry, applications of nanobiotechnology in petroleum refining, and how nanobiotechnology can be used for petroleum wastewater treatment.This book covers the very important principle of nanobiotechnology as applied in the petroleum industry and how it can be used for:Oil recoveryMicrobial enhanced oil recoveryPetroleum refinery, such as, for example, desulfurization, denitrogenation, demetallization, biotransformation, and bio-upgradingBioremediation of oil polluted soil and waterMitigation of microbial corrosion and bio-foulingToxicity of nano-materials and its obstacles upon applicationNanobiotechnology in petroleum industry and the 17 goals of sustainable developmentThe advantages of the application of nanobiotechnology in the oil industries are enormous and clearly outweigh any negligible cons. The success can have a huge impact on the exploration, production, refining, mitigation of corrosion, waste management, and economics. This informative volume will be valuable for petroleum engineers and petroleum microbiologists, scientists, and researchers concerned with nanotechnology, environmental pollution, petroleum biotechnology, petroleum microbiology, petroleum refining, and the petroleum industry in general.
