摘要:

为解决中国海带加工附加值低、褐藻胶高值化利用受限及化肥滥用引发的生态问题,综述了海带生物降解技术及其产物在农业领域的应用。重点阐述了褐藻胶裂解酶的来源、分类、结构及作用机理,以及微生物发酵与酶解协同降解方式,并综述了降解产物作为促生剂、抗逆诱导剂、土壤改良剂及抑菌剂在农业中的应用。研究表明,海带生物降解产物在农业领域应用潜力巨大,但仍面临作用机制不明、产业规范不足等挑战。通过技术创新与协作,有望推动绿色农业发展,为海藻高值化利用提供有效路径。

Abstract:

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.
