According to Xinhua news agency, Tokyo, September 2, Japanese researchers have found that by changing the gene responsible for regulating biological rhythm in cyanobacteria cells, the production of useful amino acids can be doubled Researchers at Meiji University, Japan, have worked with colleagues at the Japanese Institute of physics and chemistry to study the cyanobacteria, a communique said Under the irradiation of light, Colletotrichum will absorb carbon dioxide and generate energy in the body The team believes that if we change the catabolic process of energy production of Colletotrichum, it is possible to produce more amino acids For this reason, they use gene technology to carry out research The researchers found that there is a gene called "RPAA" in the algae, which is responsible for regulating the biological rhythm and metabolism After changing the gene to over express, researchers found that the production of useful amino acids such as glycine and lysine, which are used as food additives and livestock feed, increased significantly The amount of glycine produced by gene regulation is twice as much as that of wild algae, and lysine is 4 times as much The researchers say the new method will help reduce the cost of manufacturing useful amino acids, and they will next test whether they can use this method to make other useful substances.
