Inner Workings: How bacteria could help recycle electronic

C. violaceum didn't make enough cyanide to remove gold efficiently. Part of the reason was that only dense populations of the bacteria make the enzyme. So in a 2013 study, Ting's team accelerated the process and boosted cyanide production by creating two new strains of the bacteria, each of which had an extra copy of the genes controlling enzyme production ( 2 ).
