ABSTRACT
Waste management is a gigantic problem across the globe. To resolve this issue, many processes and methods for waste management have been adopted, but better strategies and methods need to be developed for proper waste management. In today's world, with the advent of microbiological techniques and biotechnology, novel industrial processes are being developed to deal with waste management. The biggest advantage of using microorganisms and their products is they are renewable, cheap and easy to produce. Many of the biorefinery processes can be modified into better sustainability by utilizing enzymes that can be stable at high temperatures. The thermostable enzyme(s) of thermophiles, often proposed for industrial waste management, have been advocated to replace or supplement traditional chemical processes to reduce the environmental burden. Thermophilic enzyme and microbial processes are stable, rapid and less expensive and can facilitate reactant activity and product recovery. Thermophilic bacteria have found applications in chemical feedstock and fuel production, bioconversion of wastes, enzyme technology, and much more. This chapter shows the fundamental and applied aspects of thermophilic bacteria with an industrial interest. There are different advantages of thermozymes applications like reduced risk of microbial contamination, increased mass transfer, lower viscosity and improved susceptibility of some proteins to enzyme molecules. This chapter covers thermostabilizing strategies and some properties of thermostable applications regarding waste management in food processing, agriculture and other industries.
