New technology can increase the survival rate of nematodes at low temperature by 10 times

TOKYO, May 16 (Xinhua) -- A new study in Japan shows that the transfer of ice-binding proteins into a worm's body by genetically modified methods can improve its 24-hour feeding survival rate by about 10 times at minus 5 degrees Celsius. The findings have been published in the British journal Scientific Reports.
researchers from japan's Institute of Industrial Technology and the University of Tokyo used genetically modified methods to transfer the Suri hidden rod worms to ice-binding proteins to compare their viability at low temperatures. The results showed that after transferring to a bacterial ice binding protein, the survival rate of the worm in 24 hours at minus 5 degrees Celsius increased from about 7% to about 72%, and the survival rate increased by 10 times under low temperature conditions.
, the survival rate of this genetically modified worm has also increased in a zero degree Celsius environment. This suggests that ice-binding proteins can also function as cell protection in environments where ice crystals are virtually non-existent.
binding protein is a protein in fish and microorganisms that help cells resist low temperatures, such as fish and microorganisms that survive at low temperatures. The team believes that further research into the genetically modified transfer method of ice-binding proteins could help develop new cryogenic preservation techniques for transplanting organs and food.
