ABSTRACT
This chapter discusses the application of enzyme-based technologies, as it relates to green chemistry practices as well as the development of green technologies principles and devices. Biocatalysis is defined as the utilization of biological molecules derived from an organic source to catalyze the chemical transformation of other organic molecules or compounds. The enzyme immobilization techniques consists of the immobilization of the target enzymes onto a prefabricated carrier or support. Industrial chemical syntheses of widely ranging types and scales are ubiquitous throughout the modern world, for producing necessary goods and chemicals to be used in everyday life. Immobilized enzyme technology has use in the production of biofuels such as methanol and biodiesel. Enzyme-based biosensors are highly advantageous due to the natural selectivity and specificity of enzymes toward a target molecule, and their capability to sense such analytes in trace amounts. The performance of a biofuel cell is generally reported using two main parameters: the maximum power density and open circuit voltage.
