Japanese scientists use photosynthesis bacteria to make spider slys

Spider silk is known for its toughness, it is made of silk protein. Spider silk can be used to make a variety of useful materials, but it is very difficult to obtain enough silk protein, because each spider produces only a small amount of silk protein. Scientists at the Institute for Sustainable Resource Research at the Institute of Science and Technology in Japan published a paper in The Communications Biology, reporting that they have successfully used photosynthesis bacteria to create spider silk.

The study is expected to usher in a new era of mass production of spiders in photosynthesis plants. Due to its amazing physical properties, spider silk can be used to make tear-resistant clothing, auto parts and aerospace components.

Japanese researchers genetically engineered photosynthesis bacteria to produce MaSp1 proteins that play a key role in the intensity of spiders. They also found a simple formula to efficiently produce silk protein.
