海带的生物降解及海藻提取物在农业领域中的应用OA

The study aimed to solve the ecological problems caused by the low added value of Laminaria japonica processing,the restriction of high-value use of fucoidan due to its structural characteristics and the abuse of chemical fertilizers in China,and to explore the application of L.japonica biodegradation technology and its products in agricultural field,so as to provide reference for the development of marine algal resources.The necessity and advantages of biodegradation were analyzed by summarizing the main components and structural characteristics of L.japonica;the biodegradation technology was elaborated,including the source,classification,structure and mechanism of action of fucoidan laccases,as well as the synergistic degradation methods of microbial fermentation and enzymatic degradation;and the application of the degradation products as biopromoter,antiretroviral inducer,soil conditioner and bacteriostat in agriculture were summarized.The application value of L.japonica biodegradation products in agriculture is remarkable,although there are challenges such as the unclear mechanism of action and the lack of industrial specifications.Through technological innovation and collaboration,it is expected to promote the development of green agriculture and provide an effective path for the high-value utilization of seaweeds.
