泥炭和褐煤是腐植酸的主要来源。通过紫外-荧光光谱分析等可差异性地表征泥炭、褐煤中的黑腐酸、棕腐酸和黄腐酸。腐植酸具有多种生物活性组分,利用工程化的分枝杆菌可定向降解得到某些甾类化合物,利用特异性酵母菌的异源合成可得到萜类和腐植酸萜类组分,通过浓缩、分离、纯化等处理工艺,可以制备具有抗菌,改善植物营养条件的生物农药。
Peat and lignite are the main sources of humic acid. The peat, humic acid, fulvic acid and fulvic acid in peat and lignite can be differentially characterized by UV-fluorescence spectroscopy and the like. Humic acid has a variety of bioactive components, the use of engineered mycobacteria can be directed degradation of certain steroids, the use of heterologous synthesis of yeast can be obtained terpenoids and humic acid terpenoid components, by concentration , Separation, purification and other treatment processes, can be prepared with antibacterial and improve the nutritional status of plant biological pesticides.
