Marine bacteria engineered to synthesize spider silk [Full subscriber]

Spiders produce strong and lightweight threads called draglines that are made from silk proteins. Although they can be used to manufacture a number of useful materials, getting enough of the protein is difficult because only a small amount can be produced by each tiny spider. Now, researchers at the RIKEN Center for Sustainable Resource Science (CSRS) in Japan, led by Keiji Numata, reported that they succeeded in producing the spider silk from engineered marine photosynthetic bacteria.
