Editorial: Marine Microorganisms and Their Enzymes With Biotechnological Application

The understanding and exploration of marine microbial resources is a new area with enormous potentialities in numerous fields of research and application. Due to the extreme and fluctuating salinity, pressure, and temperature of the marine environment, marine microorganisms are forced to develop unique metabolic pathways to adapt to this environment, producing enzymes that show different properties compared to the analogous ones obtained from terrestrial sites. Besides, being an important source of new active substances, and thanks to the disclosure of the particular the genome of marine microorganisms, as well as to the application of marine microbial engineering and enzyme engineering technologies, marine microorganisms and their enzymes show important development prospects in the agri-food industry, medicine, and other biotechnological fields. At present, the research on microbial physiology and metabolism under extreme marine conditions has made remarkable progress, and the application of this knowledge has also been applied for the restoration of the marine environment.
