The study of micro-organisms in Britain in the early twentieth century
was dominated by medical concerns, with little support for non-medica
l research. This paper examines the way in which microbes came to have
a place in industrial contexts in the 1920s and early 1930s. Their in
dustrial capacity was only properly recognized during World War I, wit
h the development of fermentation processes to make required organic c
hemicals. Post-war research sponsored by chemical and food industries
and the D.S.I.R. established the industrial significance of microbes.
The primary focus here is the D.S.I.R. work which aimed to pull microb
es away from medical concerns and promote the role of microbes in Brit
ish industry.
