Publicity about Antibiotic Research

Framed photograph of David Hopwood showing Hopwood above various coloured Petrie dishes, colour print, London Picture Service (4/1402/01/12/C) with typed page glued to back describing the background to the photograph entitled 'Breakthrough in Antibiotic Research'. Used for publicity about the first hybrid antibiotic using genetic engineering called meder-rhodin, produced at John Innes by a team led by Hopwood. Meder-rhodin was made by transferring genes from one strain of streptomycetes into another.
