Fermentation Of Fulvic Acid Extraction From Plant Physiology

The research of producing humic acids with non-coal raw material has gotten a great development in recent years, especially in research of utilizing microorganism to produce humic acids with the agricultural wastes as raw materials. The way of utilizing several microorganism to produce fulvic acids with discarded apple pomace as main raw materials has been studied in our laboratory before.This paper has studied ways to separate fulvic acids from fermented apple pomace. And also the influence of the separated fulvic acids on plant has been studied. All the study was done to complete the craft course of producing fulvic acids from discarded apple pomace by microorganism fermenting. The study build the basis for using this craft course on a large scale. At the same time, the study make certain the exciting prospect of the wide use of the fulvic acids in the field of agriculture.To this complicated biochemical system of fermented apple pomace, this research adopts the alkali liquor to soak the fermented pomace, and then clean the steep by acid liquor and a centrifuge. At last, water in the steep must be get rid of and the crude product of fulvic acids can be obtained. The crude product must be purification further more. The purification methods have been studied and the purity of the product can be 95%.The influence on plant of the crude product was tested. It was proved that fulvic acids can enhance the ability of plant to resist drought and the ability of root system to absorb.
