Researchers turn reproduction bee silk

Australian researchers formed artificially produced honey bee silk using genetically adapted bacteria. CSIRO entomologist Dr Tara Sutherland, who led the group of researchers, says "the silks would be good for hard, lightweight textiles, and high-strength applications like superior aviation and oceanic composites."

"It would also be helpful in medical applications with sutures, artificial tendons and ligaments." To make their insect silk from E. coli, Sutherland and colleagues initially had to genetically change the bacteria. "Honey bee silk was favored because E. coli can't produce long stranded silks like spiders or silk worms make, however can make the shorter protein strands, made by honey bees," says Sutherland.

"Numerous hard works have been prepared to express other invertebrate silks in transgenic systems but the complicated structure of the silk genes in added organisms means that producing silk exterior silk glands is extremely not easy."

"We had earlier identified the honeybee silk genes and knew the silk was fixed by four small non-repetitive genes - a lot simpler understanding which prepared them excellent candidates for transgenic silk production."
