General information
The development of biological fuel cells (BFCs) based on oxidoreductases (hydrogenases (Hyds), glucose oxidases, glycerol oxidases, and cholesterol oxidases) is a prerequisite for the production of a new generation of electronic devices for industry, medicine, and the environment. However, one of the most important issues in the operation of BFC is the electron transfer between immobilized enzymes and electrodes. Application of siderophile nanoparticles (SPNs) (Au, Co, Fe, Mn, Ni) with high affinity for iron could be an effective tool to improve electrochemical properties of BFC electrodes. On the other hand, the activity of enzymes depends on both microbial growth and experimental conditions, which requires the careful design of culture conditions. During this project, new approaches for continuous organic waste management in Armenia will be developed. To achieve this, different microbes (Ralstonia eutropha and Escherichia coli) of biotechnological interest will be cultivated to obtain biomass for enzyme production. Moreover, the development of methods for the immobilization of these enzymes and SNPs and obtaining of nano-composites in polymer films will be optimized and the conditions for stabilization of the electrochemical systems will be determined.
