Researchers from Japan Institute of Physical and Chemical Research recently discovered that substances that have antibacterial and moisturizing effects can be extracted from giant jellyfish that affect marine fishing and are expected to serve as raw materials for drugs and cosmetics.
This giant jellyfish, known as the Echizen jellyfish, generally exceeds 1 meter in diameter, and some individuals even have diameters of 2 to 3 meters. Affected by the global warming, in recent years, they have appeared in large numbers in the waters around Japan every autumn. They often hang on fishing nets or break fishing nets, causing many troubles for marine fishing operations.
According to a report by the Japanese media on the 4th, the new substance extracted by the Institute of Physical and Chemical Research is a compound that closely resembles the main component of human saliva and gastric juice called mucin. Mucin adsorption on viruses and bacteria weakens its infectivity. effect. Currently, mucin extracted from beef saliva has been used as a raw material for food additives and gastrointestinal drugs. This new material extracted from giant jellyfish has the same efficacy as mucin.
The research team said that 1 kg of powdery mucin compound can be extracted from the above giant jellyfish with a total weight of 3 tons. At present, they are conducting more large-scale experiments with a view to putting the relevant research results into practical use as early as possible.
This is an oil hardened steel, which is universally used by the ball and roller bearing industry. This steel has very good hardness, very good physical characteristics and excellent wear resistance.
