Kelp(Laminaria japonica Aresch) is known as kelp, lunbu, and river cabbage which is one of the important economic algae in marine aquaculture.
It is a kind of giant edible algae belonging to the genus Laminaceae, the family Laminaria of the Phaeodactylum family. The leaves of kelp sporophyte are band-shaped, brown, and lustrous, and the middle of the leaves runs through two longitudinal grooves to form the "middle band". Kelp has rich nutritional value, such as protein, amino acids, cellulose, vitamins, iodine, iron, zinc and more than 60 kinds of nutrients are present in kelp tissue.
Nowadays, under the requirements of sustainable development and the premise of food safety, laminarin because of its unique biological activity, has become a key development direction in the field of pesticide formulations. In terms of the field of diseases caused by plant pathogenic microorganisms, the application of such green biological pesticides has a good control effect of it, which is in line with the currently advocated plant protection strategy of "prevention is better than cure".
Kelp has rich iodine, vitamins, minerals, proteins, fatty acids, mannitol, fucoidan, seaweed polyphenols, and other nutrients, and about 60 kinds of physiologically active ingredients. This is the reason why kelp extract has great potential in the agriculture & food market.
Dora Laminaria Japonica Enzymatic Extraction Technology
In order to take the best advantage of kelp(Laminaria Japonica), Dora Agritech is focused on researching enzymatic hydrolysis technology.
During the process of extracting kelp nutrients, add alginate lyse to degrade the alginate rich in kelp cell walls to obtain oligosaccharide fragments with good water solubility and easy absorption and utilization, reducing the viscosity of kelp and increasing water solubility.
Meanwhile, it opens the cell wall, dissolves the intracellular substances, and dissolves more nutrients into the extract.
Dora Agri compares and analyzes various nutrients in the kelp extract of different extraction methods, providing a strong scientific basis for the further development and utilization of kelp.
Most mineral elements content in the kelp extract increased after enzymolysis, the content of Ca increased by 2.2 times and Mn increased by 5.5 times, the content of trace element Zn also increased by nearly 2 times. After the enzyme was added, the content of mineral elements in the kelp extract has a certain increased, and the enzymatic hydrolysis strengths the nutrition of the kelp extract.
Effect of Enzymolysis Technology on Stress Resistance
Enzymatic hydrolysis of seaweed extract can enhance the ability of corn, wheat, and other crops to resist adversity and improve fertilizer utilization efficiency.
In terms of drought stress, plants were dwarfed, and wilting symptoms were obvious during the drought. However, the stem base of the plants applied with the enzymatic hydrolyzed kelp extract and NPK was thick and sturdy, which was less affected by drought stress.
The height, biomass, relative water content, and SPAD of cabbage leaves were significantly increased under the combined application of kelp enzymatic hydrolyzate and NPK. The biomass of cabbage in the enzymatic hydrolysate was 13.74% higher than that in the bacterial hydrolysate.
