Abstract:

Natural melanin is a polyhydroxyindole or polyhydroxyphenol polymer synthesized and secreted by biological cells,which is soluble in alkali but insoluble in water and other organic solvents,and is widely found in various animals,plants and microorganisms. Current researches have shown that there are a variety of biological activities in natural fungal melanin,and it is an important biological material and resource with a wide range of applications in many fields. This paper reviews the current status of research on the classification,structure,synthesis pathway,physicochemical properties and biological activities of fungal melanin,and points out that fungal melanin has great potential and value in production applications. Furthermore,by comprehensively comparing four fungal melanin preparation methods,including extraction by leaching,ultrasonic-assisted extraction,ultrasonic-microwave-assisted extraction and enzyme-ultrasonic synergistic extraction,a reference for the efficient production of fungal melanin is provided. Finally,it summarizes the current situation of the development and application of fungal melanin in agriculture,industry,medicine and other industries at home and abroad in recent years,and discusses the significance and issues of fungal melanin in industrial application. This paper provides reference for promoting the application and development direction of fungal melanin industry in China.
